What are the noise and vibration characteristics of engineering chains?
Engineering chains, like other types of roller chains, can produce noise and vibrations during their operation. The noise and vibration characteristics of engineering chains depend on several factors:
- Lubrication: Proper lubrication of the chain can help reduce friction between the chain’s components, leading to smoother operation and lower noise levels.
- Chain Condition: A well-maintained chain with proper tension and minimal wear is likely to produce less noise and vibration compared to a worn or damaged chain.
- Alignment: Proper alignment of the sprockets and the chain is essential to minimize lateral forces, which can contribute to increased noise and vibration.
- Load and Speed: Heavier loads and higher speeds can increase the dynamic forces within the chain, leading to more pronounced noise and vibration.
- Environmental Factors: External factors, such as temperature, humidity, and contaminants, can influence the chain’s noise and vibration characteristics.
Chain noise and vibration can be managed through various measures:
- Chain Design: Some chains are designed with noise reduction features, such as special profile plates or noise-dampening materials.
- Lubrication: Using high-quality and appropriate lubricants can help reduce friction and noise.
- Tensioning: Properly tensioned chains experience less vibration and are less likely to produce noise.
- Maintenance: Regular inspection and maintenance can identify and address any issues that may contribute to increased noise and vibration.
- Isolation: In some applications, adding vibration isolators or dampeners can help reduce the transmission of noise and vibrations to surrounding structures.
It’s important to consider the specific requirements of the application and consult with chain manufacturers or experts to select the most suitable engineering chain and implement noise and vibration mitigation strategies when necessary.
What are the benefits of using an engineering chain over other power transmission methods?
Engineering chains offer several advantages over other power transmission methods, making them a preferred choice in various industrial applications:
- High Strength: Engineering chains are designed to handle heavy loads and high torque, making them suitable for demanding applications that require robust and reliable power transmission.
- Wide Range of Sizes: These chains are available in a wide range of sizes and configurations, allowing for flexibility in design and accommodating various application requirements.
- Durable and Long-Lasting: When properly maintained, engineering chains have a long service life, reducing the need for frequent replacements and minimizing downtime in industrial operations.
- Adaptable to Harsh Environments: Engineering chains are capable of operating in harsh conditions, including dusty, dirty, or corrosive environments, without compromising their performance.
- Shock Load Resistance: The design of engineering chains allows them to handle sudden impact forces and shock loads, which can occur in certain industrial processes.
- Cost-Effective: Engineering chains often provide a cost-effective solution for power transmission compared to other methods, especially in high-load applications.
- Simple Installation: With proper alignment and tensioning, engineering chains are relatively easy to install, reducing installation time and labor costs.
- Bi-Directional Power Transmission: Engineering chains can transmit power in both forward and reverse directions, making them suitable for applications requiring bidirectional motion.
- Low Maintenance: Regular maintenance, such as lubrication and inspection, can keep engineering chains in good working condition, reducing overall maintenance costs.
- Reduction of Noise and Vibration: When adequately lubricated and aligned, engineering chains can operate quietly and with minimal vibration, contributing to a more comfortable and safer working environment.
Despite their many advantages, it’s essential to consider the specific requirements of each application before selecting an engineering chain. Factors such as load capacity, speed, environmental conditions, and space constraints should be taken into account to ensure the chain’s optimal performance and longevity.
In summary, engineering chains are a versatile and reliable power transmission method, offering a range of benefits that make them well-suited for use in various industrial settings.
Can engineering chains be used in high-speed applications?
Yes, engineering chains can be used in high-speed applications, but their suitability depends on various factors. While some engineering chains are designed to handle high-speed operation, others may not be suitable for such applications. Here are some considerations:
1. Chain Type: Different types of engineering chains have varying capabilities when it comes to high-speed operation. For example, roller chains are commonly used in industrial applications and can handle moderate to high speeds efficiently. On the other hand, conveyor chains or specialty chains may have limitations on speed due to their design and intended use.
2. Manufacturer Specifications: Check the manufacturer’s specifications and recommendations for the engineering chain you plan to use. Manufacturers often provide maximum allowable speeds for their chains based on factors such as chain size, material, and construction.
3. Lubrication and Maintenance: Proper lubrication and maintenance are critical for high-speed applications. Adequate lubrication reduces friction and wear, allowing the chain to operate smoothly at higher speeds. Regular maintenance ensures that the chain remains in good condition and minimizes the risk of unexpected failures.
4. Load and Tension: High-speed applications can place additional loads and tension on the engineering chain. It is essential to ensure that the chain can handle the increased loads and tension without stretching excessively or experiencing premature wear.
5. Environmental Conditions: Consider the environmental factors that may affect the chain’s performance at high speeds. Temperature, humidity, and the presence of contaminants can impact the chain’s wear and durability.
6. Safety Considerations: High-speed applications require careful consideration of safety measures. Ensure that all safety guidelines and regulations are followed to prevent accidents or injuries resulting from chain failure.
In summary, engineering chains can be used in high-speed applications, but it is essential to select the appropriate chain type and ensure proper maintenance and lubrication. Consulting with chain manufacturers or experts can help you determine the most suitable engineering chain for your specific high-speed application, ensuring safe and reliable operation.

ROLLER CHAIN
Roller chain or bush roller chain is the type of chain drive most commonly used for transmission of mechanical power on many kinds of domestic, industrial and agricultural machinery, including conveyors, wire- and tube-drawing machines, printing presses, cars, motorcycles, and bicycles. It consists of a series of short cylindrical rollers held together by side links. It is driven by a toothed wheel called a sprocket. It is a simple, reliable, and efficient means of power transmission.
CONSTRUCTION OF THE CHAIN
Two different sizes of roller chain, showing construction.
There are 2 types of links alternating in the bush roller chain. The first type is inner links, having 2 inner plates held together by 2 sleeves or bushings CHINAMFG which rotate 2 rollers. Inner links alternate with the second type, the outer links, consisting of 2 outer plates held together by pins passing through the bushings of the inner links. The “bushingless” roller chain is similar in operation though not in construction; instead of separate bushings or sleeves holding the inner plates together, the plate has a tube stamped into it protruding from the hole which serves the same purpose. This has the advantage of removing 1 step in assembly of the chain.
The roller chain design reduces friction compared to simpler designs, resulting in higher efficiency and less wear. The original power transmission chain varieties lacked rollers and bushings, with both the inner and outer plates held by pins which directly contacted the sprocket teeth; however this configuration exhibited extremely rapid wear of both the sprocket teeth, and the plates where they pivoted on the pins. This problem was partially solved by the development of bushed chains, with the pins holding the outer plates passing through bushings or sleeves connecting the inner plates. This distributed the wear over a greater area; however the teeth of the sprockets still wore more rapidly than is desirable, from the sliding friction against the bushings. The addition of rollers surrounding the bushing sleeves of the chain and provided rolling contact with the teeth of the sprockets resulting in excellent resistance to wear of both sprockets and chain as well. There is even very low friction, as long as the chain is sufficiently lubricated. Continuous, clean, lubrication of roller chains is of primary importance for efficient operation as well as correct tensioning.
LUBRICATION
Many driving chains (for example, in factory equipment, or driving a camshaft inside an internal combustion engine) operate in clean environments, and thus the wearing surfaces (that is, the pins and bushings) are safe from precipitation and airborne grit, many even in a sealed environment such as an oil bath. Some roller chains are designed to have o-rings built into the space between the outside link plate and the inside roller link plates. Chain manufacturers began to include this feature in 1971 after the application was invented by Joseph Montano while working for Whitney Chain of Hartford, Connecticut. O-rings were included as a way to improve lubrication to the links of power transmission chains, a service that is vitally important to extending their working life. These rubber fixtures form a barrier that holds factory applied lubricating grease inside the pin and bushing wear areas. Further, the rubber o-rings prevent dirt and other contaminants from entering inside the chain linkages, where such particles would otherwise cause significant wear.[citation needed]
There are also many chains that have to operate in dirty conditions, and for size or operational reasons cannot be sealed. Examples include chains on farm equipment, bicycles, and chain saws. These chains will necessarily have relatively high rates of wear, particularly when the operators are prepared to accept more friction, less efficiency, more noise and more frequent replacement as they neglect lubrication and adjustment.
Many oil-based lubricants attract dirt and other particles, eventually forming an CHINAMFG paste that will compound wear on chains. This problem can be circumvented by use of a “dry” PTFE spray, which forms a solid film after application and repels both particles and moisture.
VARIANTS DESIGN
Layout of a roller chain: 1. Outer plate, 2. Inner plate, 3. Pin, 4. Bushing, 5. Roller
If the chain is not being used for a high wear application (for instance if it is just transmitting motion from a hand-operated lever to a control shaft on a machine, or a sliding door on an oven), then 1 of the simpler types of chain may still be used. Conversely, where extra strength but the smooth drive of a smaller pitch is required, the chain may be “siamesed”; instead of just 2 rows of plates on the outer sides of the chain, there may be 3 (“duplex”), 4 (“triplex”), or more rows of plates running parallel, with bushings and rollers between each adjacent pair, and the same number of rows of teeth running in parallel on the sprockets to match. Timing chains on automotive engines, for example, typically have multiple rows of plates called strands.
Roller chain is made in several sizes, the most common American National Standards Institute (ANSI) standards being 40, 50, 60, and 80. The first digit(s) indicate the pitch of the chain in eighths of an inch, with the last digit being 0 for standard chain, 1 for lightweight chain, and 5 for bushed chain with no rollers. Thus, a chain with half-inch pitch would be a #40 while a #160 sprocket would have teeth spaced 2 inches apart, etc. Metric pitches are expressed in sixteenths of an inch; thus a metric #8 chain (08B-1) would be equivalent to an ANSI #40. Most roller chain is made from plain carbon or alloy steel, but stainless steel is used in food processing machinery or other places where lubrication is a problem, and nylon or brass are occasionally seen for the same reason.
Roller chain is ordinarily hooked up using a master link (also known as a connecting link), which typically has 1 pin held by a horseshoe clip rather than friction fit, allowing it to be inserted or removed with simple tools. Chain with a removable link or pin is also known as cottered chain, which allows the length of the chain to be adjusted. Half links (also known as offsets) are available and are used to increase the length of the chain by a single roller. Riveted roller chain has the master link (also known as a connecting link) “riveted” or mashed on the ends. These pins are made to be durable and are not removable.
USE
An example of 2 ‘ghost’ sprockets tensioning a triplex roller chain system
Roller chains are used in low- to mid-speed drives at around 600 to 800 feet per minute; however, at higher speeds, around 2,000 to 3,000 feet per minute, V-belts are normally used due to wear and noise issues.
A bicycle chain is a form of roller chain. Bicycle chains may have a master link, or may require a chain tool for removal and installation. A similar but larger and thus stronger chain is used on most motorcycles although it is sometimes replaced by either a toothed belt or a shaft drive, which offer lower noise level and fewer maintenance requirements.
The great majority of automobile engines use roller chains to drive the camshaft(s). Very high performance engines often use gear drive, and starting in the early 1960s toothed belts were used by some manufacturers.
Chains are also used in forklifts using hydraulic rams as a pulley to raise and lower the carriage; however, these chains are not considered roller chains, but are classified as lift or leaf chains.
Chainsaw cutting chains superficially resemble roller chains but are more closely related to leaf chains. They are driven by projecting drive links which also serve to locate the chain CHINAMFG the bar.

A perhaps unusual use of a pair of motorcycle chains is in the Harrier Jump Jet, where a chain drive from an air motor is used to rotate the movable engine nozzles, allowing them to be pointed downwards for hovering flight, or to the rear for normal CHINAMFG flight, a system known as Thrust vectoring.
WEAR
The effect of wear on a roller chain is to increase the pitch (spacing of the links), causing the chain to grow longer. Note that this is due to wear at the pivoting pins and bushes, not from actual stretching of the metal (as does happen to some flexible steel components such as the hand-brake cable of a motor vehicle).
With modern chains it is unusual for a chain (other than that of a bicycle) to wear until it breaks, since a worn chain leads to the rapid onset of wear on the teeth of the sprockets, with ultimate failure being the loss of all the teeth on the sprocket. The sprockets (in particular the smaller of the two) suffer a grinding motion that puts a characteristic hook shape into the driven face of the teeth. (This effect is made worse by a chain improperly tensioned, but is unavoidable no matter what care is taken). The worn teeth (and chain) no longer provides smooth transmission of power and this may become evident from the noise, the vibration or (in car engines using a timing chain) the variation in ignition timing seen with a timing light. Both sprockets and chain should be replaced in these cases, since a new chain on worn sprockets will not last long. However, in less severe cases it may be possible to save the larger of the 2 sprockets, since it is always the smaller 1 that suffers the most wear. Only in very light-weight applications such as a bicycle, or in extreme cases of improper tension, will the chain normally jump off the sprockets.
The lengthening due to wear of a chain is calculated by the following formula:
M = the length of a number of links measured
S = the number of links measured
P = Pitch
In industry, it is usual to monitor the movement of the chain tensioner (whether manual or automatic) or the exact length of a drive chain (one rule of thumb is to replace a roller chain which has elongated 3% on an adjustable drive or 1.5% on a fixed-center drive). A simpler method, particularly suitable for the cycle or motorcycle user, is to attempt to pull the chain away from the larger of the 2 sprockets, whilst ensuring the chain is taut. Any significant movement (e.g. making it possible to see through a gap) probably indicates a chain worn up to and beyond the limit. Sprocket damage will result if the problem is ignored. Sprocket wear cancels this effect, and may mask chain wear.
CHAIN STRENGTH
The most common measure of roller chain’s strength is tensile strength. Tensile strength represents how much load a chain can withstand under a one-time load before breaking. Just as important as tensile strength is a chain’s fatigue strength. The critical factors in a chain’s fatigue strength is the quality of steel used to manufacture the chain, the heat treatment of the chain components, the quality of the pitch hole fabrication of the linkplates, and the type of shot plus the intensity of shot peen coverage on the linkplates. Other factors can include the thickness of the linkplates and the design (contour) of the linkplates. The rule of thumb for roller chain operating on a continuous drive is for the chain load to not exceed a mere 1/6 or 1/9 of the chain’s tensile strength, depending on the type of master links used (press-fit vs. slip-fit)[citation needed]. Roller chains operating on a continuous drive beyond these thresholds can and typically do fail prematurely via linkplate fatigue failure.
The standard minimum ultimate strength of the ANSI 29.1 steel chain is 12,500 x (pitch, in inches)2. X-ring and O-Ring chains greatly decrease wear by means of internal lubricants, increasing chain life. The internal lubrication is inserted by means of a vacuum when riveting the chain together.
CHAIN STHangZhouRDS
Standards organizations (such as ANSI and ISO) maintain standards for design, dimensions, and interchangeability of transmission chains. For example, the following Table shows data from ANSI standard B29.1-2011 (Precision Power Transmission Roller Chains, Attachments, and Sprockets) developed by the American Society of Mechanical Engineers (ASME). See the references[8][9][10] for additional information.

| 3⁄4 | 6⁄8 | 60 | 1⁄2 |
| 1 | 8⁄8 | 80 | 5⁄8 |
Notes:
1. The pitch is the distance between roller centers. The width is the distance between the link plates (i.e. slightly more than the roller width to allow for clearance).
2. The right-hand digit of the standard denotes 0 = normal chain, 1 = lightweight chain, 5 = rollerless bushing chain.
3. The left-hand digit denotes the number of eighths of an inch that make up the pitch.
4. An “H” following the standard number denotes heavyweight chain. A hyphenated number following the standard number denotes double-strand (2), triple-strand (3), and so on. Thus 60H-3 denotes number 60 heavyweight triple-strand chain.
A typical bicycle chain (for derailleur gears) uses narrow 1⁄2-inch-pitch chain. The width of the chain is variable, and does not affect the load capacity. The more sprockets at the rear wheel (historically 3-6, nowadays 7-12 sprockets), the narrower the chain. Chains are sold according to the number of speeds they are designed to work with, for example, “10 speed chain”. Hub gear or single speed bicycles use 1/2″ x 1/8″ chains, where 1/8″ refers to the maximum thickness of a sprocket that can be used with the chain.
Typically chains with parallel shaped links have an even number of links, with each narrow link followed by a broad one. Chains built up with a uniform type of link, narrow at 1 and broad at the other end, can be made with an odd number of links, which can be an advantage to adapt to a special chainwheel-distance; on the other side such a chain tends to be not so strong.
Roller chains made using ISO standard are sometimes called as isochains.

Can engineering chains be used in overhead or inverted applications?
Yes, engineering chains can be used in both overhead and inverted applications, provided they are properly selected and installed. These types of applications are common in various industries, including material handling, automotive, and food processing. Engineering chains are versatile and well-suited for such applications due to their robust construction, flexibility, and ability to handle heavy loads.
Overhead applications involve suspending the chain from overhead beams or structures, while inverted applications require the chain to run on the underside of the conveyor or equipment. Some factors to consider when using engineering chains in these applications include:
- Corrosion Resistance: For overhead applications in outdoor environments or areas with exposure to moisture, it is essential to use engineering chains made from corrosion-resistant materials, such as stainless steel, to prevent rust and ensure longevity.
- Lubrication: Proper and regular lubrication is crucial for chains in both overhead and inverted applications to reduce friction, wear, and noise levels. Lubrication also helps protect the chain from contaminants and moisture.
- Load Capacity: Ensure that the engineering chain selected has a sufficient load capacity to handle the weight of the conveyed materials or equipment in the application.
- Installation: Proper installation is critical for the smooth operation of the chain in overhead and inverted applications. Correct tensioning and alignment will help prevent premature wear and improve overall performance.
- Chain Speed: Consider the speed at which the chain will be running in the application, as higher speeds may require additional considerations in terms of lubrication and wear.
By taking these factors into account and following the manufacturer’s guidelines for installation, lubrication, and maintenance, engineering chains can be used effectively in overhead and inverted applications. They offer reliable and efficient power transmission and material handling solutions, making them valuable components in a wide range of industrial processes and systems.
Can engineering chains be used in marine or underwater applications?
Yes, engineering chains can be used in marine or underwater applications under certain conditions. However, several factors need to be considered to ensure their reliable performance and longevity in such environments:
1. Corrosion Resistance: Marine and underwater environments expose chains to the risk of corrosion due to saltwater exposure. Therefore, it’s crucial to select engineering chains made from corrosion-resistant materials such as stainless steel or special coatings to prevent rust and deterioration.
2. Sealing and Lubrication: Proper sealing and lubrication are essential to protect the chain’s internal components from water ingress and corrosion. Sealed or encapsulated chain designs with suitable lubricants can help maintain smooth operation even in wet conditions.
3. Material Selection: The choice of materials for the chain and sprockets should consider not only corrosion resistance but also the ability to withstand marine environments’ unique challenges, such as exposure to marine organisms, debris, and changing temperatures.
4. Load Capacity: Marine and underwater applications may involve heavy loads, so the engineering chain must be selected based on the specific load requirements to ensure safe and reliable operation.
5. Water Depth and Pressure: The depth of the underwater application and the resulting pressure can affect the chain’s performance. Special considerations may be necessary for deep-sea applications to withstand higher pressures.
6. Environmental Regulations: Depending on the location, there may be specific environmental regulations regarding the materials used in marine applications to prevent pollution and protect marine life.
7. Maintenance and Inspection: Regular maintenance and inspection are critical for identifying and addressing any signs of wear, corrosion, or damage in the engineering chain. Timely maintenance can extend the chain’s lifespan and ensure safe operation.
Overall, with proper material selection, sealing, lubrication, and maintenance, engineering chains can be used effectively in marine or underwater applications, providing reliable power transmission and motion control in these challenging environments.
Can engineering chains handle heavy loads and high torque requirements?
Yes, engineering chains are designed to handle heavy loads and high torque requirements, making them well-suited for various industrial applications that demand robust power transmission capabilities. The construction and materials used in engineering chains ensure their ability to withstand the stresses and forces associated with heavy loads and high torque.
Engineering chains are commonly used in heavy machinery, mining equipment, construction machinery, and other applications where substantial power transmission is necessary. Their sturdy design and precise engineering allow them to efficiently transmit power and handle the forces generated during operation.
The load capacity and torque-handling capabilities of engineering chains can vary depending on their design, size, and material. Manufacturers provide technical specifications and load ratings for different engineering chain types, enabling users to select the appropriate chain based on their specific application requirements.
In summary, engineering chains are well-equipped to handle heavy loads and high torque requirements, making them reliable and effective components in industrial systems that demand strength, durability, and efficient power transmission.

ROLLER CHAIN
Roller chain or bush roller chain is the type of chain drive most commonly used for transmission of mechanical power on many kinds of domestic, industrial and agricultural machinery, including conveyors, wire- and tube-drawing machines, printing presses, cars, motorcycles, and bicycles. It consists of a series of short cylindrical rollers held together by side links. It is driven by a toothed wheel called a sprocket. It is a simple, reliable, and efficient means of power transmission.
CONSTRUCTION OF THE CHAIN
Two different sizes of roller chain, showing construction.
There are 2 types of links alternating in the bush roller chain. The first type is inner links, having 2 inner plates held together by 2 sleeves or bushings CHINAMFG which rotate 2 rollers. Inner links alternate with the second type, the outer links, consisting of 2 outer plates held together by pins passing through the bushings of the inner links. The “bushingless” roller chain is similar in operation though not in construction; instead of separate bushings or sleeves holding the inner plates together, the plate has a tube stamped into it protruding from the hole which serves the same purpose. This has the advantage of removing 1 step in assembly of the chain.
The roller chain design reduces friction compared to simpler designs, resulting in higher efficiency and less wear. The original power transmission chain varieties lacked rollers and bushings, with both the inner and outer plates held by pins which directly contacted the sprocket teeth; however this configuration exhibited extremely rapid wear of both the sprocket teeth, and the plates where they pivoted on the pins. This problem was partially solved by the development of bushed chains, with the pins holding the outer plates passing through bushings or sleeves connecting the inner plates. This distributed the wear over a greater area; however the teeth of the sprockets still wore more rapidly than is desirable, from the sliding friction against the bushings. The addition of rollers surrounding the bushing sleeves of the chain and provided rolling contact with the teeth of the sprockets resulting in excellent resistance to wear of both sprockets and chain as well. There is even very low friction, as long as the chain is sufficiently lubricated. Continuous, clean, lubrication of roller chains is of primary importance for efficient operation as well as correct tensioning.
LUBRICATION
Many driving chains (for example, in factory equipment, or driving a camshaft inside an internal combustion engine) operate in clean environments, and thus the wearing surfaces (that is, the pins and bushings) are safe from precipitation and airborne grit, many even in a sealed environment such as an oil bath. Some roller chains are designed to have o-rings built into the space between the outside link plate and the inside roller link plates. Chain manufacturers began to include this feature in 1971 after the application was invented by Joseph Montano while working for Whitney Chain of Hartford, Connecticut. O-rings were included as a way to improve lubrication to the links of power transmission chains, a service that is vitally important to extending their working life. These rubber fixtures form a barrier that holds factory applied lubricating grease inside the pin and bushing wear areas. Further, the rubber o-rings prevent dirt and other contaminants from entering inside the chain linkages, where such particles would otherwise cause significant wear.[citation needed]
There are also many chains that have to operate in dirty conditions, and for size or operational reasons cannot be sealed. Examples include chains on farm equipment, bicycles, and chain saws. These chains will necessarily have relatively high rates of wear, particularly when the operators are prepared to accept more friction, less efficiency, more noise and more frequent replacement as they neglect lubrication and adjustment.
Many oil-based lubricants attract dirt and other particles, eventually forming an CHINAMFG paste that will compound wear on chains. This problem can be circumvented by use of a “dry” PTFE spray, which forms a solid film after application and repels both particles and moisture.
VARIANTS DESIGN
Layout of a roller chain: 1. Outer plate, 2. Inner plate, 3. Pin, 4. Bushing, 5. Roller
If the chain is not being used for a high wear application (for instance if it is just transmitting motion from a hand-operated lever to a control shaft on a machine, or a sliding door on an oven), then 1 of the simpler types of chain may still be used. Conversely, where extra strength but the smooth drive of a smaller pitch is required, the chain may be “siamesed”; instead of just 2 rows of plates on the outer sides of the chain, there may be 3 (“duplex”), 4 (“triplex”), or more rows of plates running parallel, with bushings and rollers between each adjacent pair, and the same number of rows of teeth running in parallel on the sprockets to match. Timing chains on automotive engines, for example, typically have multiple rows of plates called strands.
Roller chain is made in several sizes, the most common American National Standards Institute (ANSI) standards being 40, 50, 60, and 80. The first digit(s) indicate the pitch of the chain in eighths of an inch, with the last digit being 0 for standard chain, 1 for lightweight chain, and 5 for bushed chain with no rollers. Thus, a chain with half-inch pitch would be a #40 while a #160 sprocket would have teeth spaced 2 inches apart, etc. Metric pitches are expressed in sixteenths of an inch; thus a metric #8 chain (08B-1) would be equivalent to an ANSI #40. Most roller chain is made from plain carbon or alloy steel, but stainless steel is used in food processing machinery or other places where lubrication is a problem, and nylon or brass are occasionally seen for the same reason.
Roller chain is ordinarily hooked up using a master link (also known as a connecting link), which typically has 1 pin held by a horseshoe clip rather than friction fit, allowing it to be inserted or removed with simple tools. Chain with a removable link or pin is also known as cottered chain, which allows the length of the chain to be adjusted. Half links (also known as offsets) are available and are used to increase the length of the chain by a single roller. Riveted roller chain has the master link (also known as a connecting link) “riveted” or mashed on the ends. These pins are made to be durable and are not removable.
USE
An example of 2 ‘ghost’ sprockets tensioning a triplex roller chain system
Roller chains are used in low- to mid-speed drives at around 600 to 800 feet per minute; however, at higher speeds, around 2,000 to 3,000 feet per minute, V-belts are normally used due to wear and noise issues.
A bicycle chain is a form of roller chain. Bicycle chains may have a master link, or may require a chain tool for removal and installation. A similar but larger and thus stronger chain is used on most motorcycles although it is sometimes replaced by either a toothed belt or a shaft drive, which offer lower noise level and fewer maintenance requirements.
The great majority of automobile engines use roller chains to drive the camshaft(s). Very high performance engines often use gear drive, and starting in the early 1960s toothed belts were used by some manufacturers.
Chains are also used in forklifts using hydraulic rams as a pulley to raise and lower the carriage; however, these chains are not considered roller chains, but are classified as lift or leaf chains.
Chainsaw cutting chains superficially resemble roller chains but are more closely related to leaf chains. They are driven by projecting drive links which also serve to locate the chain CHINAMFG the bar.

A perhaps unusual use of a pair of motorcycle chains is in the Harrier Jump Jet, where a chain drive from an air motor is used to rotate the movable engine nozzles, allowing them to be pointed downwards for hovering flight, or to the rear for normal CHINAMFG flight, a system known as Thrust vectoring.
WEAR
The effect of wear on a roller chain is to increase the pitch (spacing of the links), causing the chain to grow longer. Note that this is due to wear at the pivoting pins and bushes, not from actual stretching of the metal (as does happen to some flexible steel components such as the hand-brake cable of a motor vehicle).
With modern chains it is unusual for a chain (other than that of a bicycle) to wear until it breaks, since a worn chain leads to the rapid onset of wear on the teeth of the sprockets, with ultimate failure being the loss of all the teeth on the sprocket. The sprockets (in particular the smaller of the two) suffer a grinding motion that puts a characteristic hook shape into the driven face of the teeth. (This effect is made worse by a chain improperly tensioned, but is unavoidable no matter what care is taken). The worn teeth (and chain) no longer provides smooth transmission of power and this may become evident from the noise, the vibration or (in car engines using a timing chain) the variation in ignition timing seen with a timing light. Both sprockets and chain should be replaced in these cases, since a new chain on worn sprockets will not last long. However, in less severe cases it may be possible to save the larger of the 2 sprockets, since it is always the smaller 1 that suffers the most wear. Only in very light-weight applications such as a bicycle, or in extreme cases of improper tension, will the chain normally jump off the sprockets.
The lengthening due to wear of a chain is calculated by the following formula:
M = the length of a number of links measured
S = the number of links measured
P = Pitch
In industry, it is usual to monitor the movement of the chain tensioner (whether manual or automatic) or the exact length of a drive chain (one rule of thumb is to replace a roller chain which has elongated 3% on an adjustable drive or 1.5% on a fixed-center drive). A simpler method, particularly suitable for the cycle or motorcycle user, is to attempt to pull the chain away from the larger of the 2 sprockets, whilst ensuring the chain is taut. Any significant movement (e.g. making it possible to see through a gap) probably indicates a chain worn up to and beyond the limit. Sprocket damage will result if the problem is ignored. Sprocket wear cancels this effect, and may mask chain wear.
CHAIN STRENGTH
The most common measure of roller chain’s strength is tensile strength. Tensile strength represents how much load a chain can withstand under a one-time load before breaking. Just as important as tensile strength is a chain’s fatigue strength. The critical factors in a chain’s fatigue strength is the quality of steel used to manufacture the chain, the heat treatment of the chain components, the quality of the pitch hole fabrication of the linkplates, and the type of shot plus the intensity of shot peen coverage on the linkplates. Other factors can include the thickness of the linkplates and the design (contour) of the linkplates. The rule of thumb for roller chain operating on a continuous drive is for the chain load to not exceed a mere 1/6 or 1/9 of the chain’s tensile strength, depending on the type of master links used (press-fit vs. slip-fit)[citation needed]. Roller chains operating on a continuous drive beyond these thresholds can and typically do fail prematurely via linkplate fatigue failure.
The standard minimum ultimate strength of the ANSI 29.1 steel chain is 12,500 x (pitch, in inches)2. X-ring and O-Ring chains greatly decrease wear by means of internal lubricants, increasing chain life. The internal lubrication is inserted by means of a vacuum when riveting the chain together.
CHAIN STHangZhouRDS
Standards organizations (such as ANSI and ISO) maintain standards for design, dimensions, and interchangeability of transmission chains. For example, the following Table shows data from ANSI standard B29.1-2011 (Precision Power Transmission Roller Chains, Attachments, and Sprockets) developed by the American Society of Mechanical Engineers (ASME). See the references[8][9][10] for additional information.

For mnemonic purposes, below is another presentation of key dimensions from the same standard, expressed in fractions of an inch (which was part of the thinking behind the choice of preferred numbers in the ANSI standard):

| 3⁄4 | 6⁄8 | 60 | 1⁄2 |
| 1 | 8⁄8 | 80 | 5⁄8 |
Notes:
1. The pitch is the distance between roller centers. The width is the distance between the link plates (i.e. slightly more than the roller width to allow for clearance).
2. The right-hand digit of the standard denotes 0 = normal chain, 1 = lightweight chain, 5 = rollerless bushing chain.
3. The left-hand digit denotes the number of eighths of an inch that make up the pitch.
4. An “H” following the standard number denotes heavyweight chain. A hyphenated number following the standard number denotes double-strand (2), triple-strand (3), and so on. Thus 60H-3 denotes number 60 heavyweight triple-strand chain.
A typical bicycle chain (for derailleur gears) uses narrow 1⁄2-inch-pitch chain. The width of the chain is variable, and does not affect the load capacity. The more sprockets at the rear wheel (historically 3-6, nowadays 7-12 sprockets), the narrower the chain. Chains are sold according to the number of speeds they are designed to work with, for example, “10 speed chain”. Hub gear or single speed bicycles use 1/2″ x 1/8″ chains, where 1/8″ refers to the maximum thickness of a sprocket that can be used with the chain.
Typically chains with parallel shaped links have an even number of links, with each narrow link followed by a broad one. Chains built up with a uniform type of link, narrow at 1 and broad at the other end, can be made with an odd number of links, which can be an advantage to adapt to a special chainwheel-distance; on the other side such a chain tends to be not so strong.
Roller chains made using ISO standard are sometimes called as isochains.

What are the noise and vibration characteristics of engineering chains?
Engineering chains, like other types of roller chains, can produce noise and vibrations during their operation. The noise and vibration characteristics of engineering chains depend on several factors:
- Lubrication: Proper lubrication of the chain can help reduce friction between the chain’s components, leading to smoother operation and lower noise levels.
- Chain Condition: A well-maintained chain with proper tension and minimal wear is likely to produce less noise and vibration compared to a worn or damaged chain.
- Alignment: Proper alignment of the sprockets and the chain is essential to minimize lateral forces, which can contribute to increased noise and vibration.
- Load and Speed: Heavier loads and higher speeds can increase the dynamic forces within the chain, leading to more pronounced noise and vibration.
- Environmental Factors: External factors, such as temperature, humidity, and contaminants, can influence the chain’s noise and vibration characteristics.
Chain noise and vibration can be managed through various measures:
- Chain Design: Some chains are designed with noise reduction features, such as special profile plates or noise-dampening materials.
- Lubrication: Using high-quality and appropriate lubricants can help reduce friction and noise.
- Tensioning: Properly tensioned chains experience less vibration and are less likely to produce noise.
- Maintenance: Regular inspection and maintenance can identify and address any issues that may contribute to increased noise and vibration.
- Isolation: In some applications, adding vibration isolators or dampeners can help reduce the transmission of noise and vibrations to surrounding structures.
It’s important to consider the specific requirements of the application and consult with chain manufacturers or experts to select the most suitable engineering chain and implement noise and vibration mitigation strategies when necessary.
What are the benefits of using an engineering chain over other power transmission methods?
Engineering chains offer several advantages over other power transmission methods, making them a preferred choice in various industrial applications:
- High Strength: Engineering chains are designed to handle heavy loads and high torque, making them suitable for demanding applications that require robust and reliable power transmission.
- Wide Range of Sizes: These chains are available in a wide range of sizes and configurations, allowing for flexibility in design and accommodating various application requirements.
- Durable and Long-Lasting: When properly maintained, engineering chains have a long service life, reducing the need for frequent replacements and minimizing downtime in industrial operations.
- Adaptable to Harsh Environments: Engineering chains are capable of operating in harsh conditions, including dusty, dirty, or corrosive environments, without compromising their performance.
- Shock Load Resistance: The design of engineering chains allows them to handle sudden impact forces and shock loads, which can occur in certain industrial processes.
- Cost-Effective: Engineering chains often provide a cost-effective solution for power transmission compared to other methods, especially in high-load applications.
- Simple Installation: With proper alignment and tensioning, engineering chains are relatively easy to install, reducing installation time and labor costs.
- Bi-Directional Power Transmission: Engineering chains can transmit power in both forward and reverse directions, making them suitable for applications requiring bidirectional motion.
- Low Maintenance: Regular maintenance, such as lubrication and inspection, can keep engineering chains in good working condition, reducing overall maintenance costs.
- Reduction of Noise and Vibration: When adequately lubricated and aligned, engineering chains can operate quietly and with minimal vibration, contributing to a more comfortable and safer working environment.
Despite their many advantages, it’s essential to consider the specific requirements of each application before selecting an engineering chain. Factors such as load capacity, speed, environmental conditions, and space constraints should be taken into account to ensure the chain’s optimal performance and longevity.
In summary, engineering chains are a versatile and reliable power transmission method, offering a range of benefits that make them well-suited for use in various industrial settings.
What materials are engineering chains typically made of?
Engineering chains are commonly made from a variety of durable and high-strength materials to ensure their performance and longevity in demanding industrial applications. The choice of material depends on factors such as the application’s requirements, environmental conditions, and the specific type of engineering chain. Some of the typical materials used for engineering chains include:
1. Carbon Steel: Carbon steel is a popular choice for engineering chains due to its excellent strength and affordability. It is suitable for many standard industrial applications where moderate strength and resistance to wear are required.
2. Alloy Steel: Alloy steel offers higher strength and better resistance to wear and fatigue compared to carbon steel. It is commonly used in heavy-duty and high-stress applications, such as mining equipment and construction machinery.
3. Stainless Steel: Stainless steel is chosen for its corrosion resistance properties, making it ideal for applications where the chain may be exposed to moisture, chemicals, or harsh environments. It is commonly used in food processing, pharmaceuticals, and outdoor applications.
4. Nickel-Plated Steel: Nickel-plated steel chains provide enhanced corrosion resistance while retaining the strength of carbon or alloy steel. They are often used in applications where both strength and corrosion resistance are important.
5. Plastic: In some cases, engineering chains may be constructed entirely from plastic or have plastic components. Plastic chains are commonly used in industries requiring low noise, lightweight, and corrosion resistance, such as the food and beverage industry and packaging applications.
6. Other Specialty Materials: Depending on the specific requirements of an application, engineering chains may also be made from other specialty materials like bronze, zinc-plated steel, or coated chains to meet particular needs.
The choice of material is crucial in determining the performance, longevity, and suitability of the engineering chain for a specific application. Manufacturers provide information on the material composition of their chains, allowing users to select the most appropriate material based on the intended use and operating conditions.

These chains will necessarily have relatively high rates of wear, particularly when the operators are prepared to accept more friction, less efficiency, more noise and more frequent replacement as they neglect lubrication and adjustment.
Many oil-based lubricants attract dirt and other particles, eventually forming an CHINAMFG paste that will compound wear on chains. This problem can be circumvented by use of a “dry” PTFE spray, which forms a solid film after application and repels both particles and moisture.
Variants in design
Layout of a roller chain: 1. Outer plate, 2. Inner plate, 3. Pin, 4. Bushing, 5. Roller
If the chain is not being used for a high wear application (for instance if it is just transmitting motion from a hand-operated lever to a control shaft on a machine, or a sliding door on an oven), then 1 of the simpler types of chain may still be used. Conversely, where extra strength but the smooth drive of a smaller pitch is required, the chain may be “siamesed”; instead of just 2 rows of plates on the outer sides of the chain, there may be 3 (“duplex”), 4 (“triplex”), or more rows of plates running parallel, with bushings and rollers between each adjacent pair, and the same number of rows of teeth running in parallel on the sprockets to match. Timing chains on automotive engines, for example, typically have multiple rows of plates called strands.
Roller chain is made in several sizes, the most common American National Standards Institute (ANSI) standards being 40, 50, 60, and 80. The first digit(s) indicate the pitch of the chain in eighths of an inch, with the last digit being 0 for standard chain, 1 for lightweight chain, and 5 for bushed chain with no rollers. Thus, a chain with half-inch pitch would be a #40 while a #160 sprocket would have teeth spaced 2 inches apart, etc. Metric pitches are expressed in sixteenths of an inch; thus a metric #8 chain (08B-1) would be equivalent to an ANSI #40. Most roller chain is made from plain carbon or alloy steel, but stainless steel is used in food processing machinery or other places where lubrication is a problem, and nylon or brass are occasionally seen for the same reason.
Roller chain is ordinarily hooked up using a master link (also known as a connecting link), which typically has 1 pin held by a horseshoe clip rather than friction fit, allowing it to be inserted or removed with simple tools. Chain with a removable link or pin is also known as cottered chain, which allows the length of the chain to be adjusted. Half links (also known as offsets) are available and are used to increase the length of the chain by a single roller. Riveted roller chain has the master link (also known as a connecting link) “riveted” or mashed on the ends. These pins are made to be durable and are not removable.
Use

Roller chains are used in low- to mid-speed drives at around 600 to 800 feet per minute; however, at higher speeds, around 2,000 to 3,000 feet per minute, V-belts are normally used due to wear and noise issues.
A bicycle chain is a form of roller chain. Bicycle chains may have a master link, or may require a chain tool for removal and installation. A similar but larger and thus stronger chain is used on most motorcycles although it is sometimes replaced by either a toothed belt or a shaft drive, which offer lower noise level and fewer maintenance requirements.
The great majority of automobile engines use roller chains to drive the camshaft(s). Very high performance engines often use gear drive, and starting in the early 1960s toothed belts were used by some manufacturers.
Chains are also used in forklifts using hydraulic rams as a pulley to raise and lower the carriage; however, these chains are not considered roller chains, but are classified as lift or leaf chains.
Chainsaw cutting chains superficially resemble roller chains but are more closely related to leaf chains. They are driven by projecting drive links which also serve to locate the chain CHINAMFG the bar.

A perhaps unusual use of a pair of motorcycle chains is in the Harrier Jump Jet, where a chain drive from an air motor is used to rotate the movable engine nozzles, allowing them to be pointed downwards for hovering flight, or to the rear for normal CHINAMFG flight, a system known as Thrust vectoring.
Wear
The effect of wear on a roller chain is to increase the pitch (spacing of the links), causing the chain to grow longer. Note that this is due to wear at the pivoting pins and bushes, not from actual stretching of the metal (as does happen to some flexible steel components such as the hand-brake cable of a motor vehicle).
With modern chains it is unusual for a chain (other than that of a bicycle) to wear until it breaks, since a worn chain leads to the rapid onset of wear on the teeth of the sprockets, with ultimate failure being the loss of all the teeth on the sprocket. The sprockets (in particular the smaller of the two) suffer a grinding motion that puts a characteristic hook shape into the driven face of the teeth. (This effect is made worse by a chain improperly tensioned, but is unavoidable no matter what care is taken). The worn teeth (and chain) no longer provides smooth transmission of power and this may become evident from the noise, the vibration or (in car engines using a timing chain) the variation in ignition timing seen with a timing light. Both sprockets and chain should be replaced in these cases, since a new chain on worn sprockets will not last long. However, in less severe cases it may be possible to save the larger of the 2 sprockets, since it is always the smaller 1 that suffers the most wear. Only in very light-weight applications such as a bicycle, or in extreme cases of improper tension, will the chain normally jump off the sprockets.
The lengthening due to wear of a chain is calculated by the following formula:
{\displaystyle \%=((M-(S*P))/(S*P))*100}
M = the length of a number of links measured
S = the number of links measured
P = Pitch
In industry, it is usual to monitor the movement of the chain tensioner (whether manual or automatic) or the exact length of a drive chain (one rule of thumb is to replace a roller chain which has elongated 3% on an adjustable drive or 1.5% on a fixed-center drive). A simpler method, particularly suitable for the cycle or motorcycle user, is to attempt to pull the chain away from the larger of the 2 sprockets, whilst ensuring the chain is taut. Any significant movement (e.g. making it possible to see through a gap) probably indicates a chain worn up to and beyond the limit. Sprocket damage will result if the problem is ignored. Sprocket wear cancels this effect, and may mask chain wear.
Chain strength
The most common measure of roller chain’s strength is tensile strength. Tensile strength represents how much load a chain can withstand under a one-time load before breaking. Just as important as tensile strength is a chain’s fatigue strength. The critical factors in a chain’s fatigue strength is the quality of steel used to manufacture the chain, the heat treatment of the chain components, the quality of the pitch hole fabrication of the linkplates, and the type of shot plus the intensity of shot peen coverage on the linkplates. Other factors can include the thickness of the linkplates and the design (contour) of the linkplates. The rule of thumb for roller chain operating on a continuous drive is for the chain load to not exceed a mere 1/6 or 1/9 of the chain’s tensile strength, depending on the type of master links used (press-fit vs. slip-fit)[citation needed]. Roller chains operating on a continuous drive beyond these thresholds can and typically do fail prematurely via linkplate fatigue failure.
The standard minimum ultimate strength of the ANSI 29.1 steel chain is 12,500 x (pitch, in inches)2. X-ring and O-Ring chains greatly decrease wear by means of internal lubricants, increasing chain life. The internal lubrication is inserted by means of a vacuum when riveting the chain together.
Chain standards
Standards organizations (such as ANSI and ISO) maintain standards for design, dimensions, and interchangeability of transmission chains. For example, the following Table shows data from ANSI standard B29.1-2011 (Precision Power Transmission Roller Chains, Attachments, and Sprockets) developed by the American Society of Mechanical Engineers (ASME). See the references[8][9][10] for additional information.
ASME/ANSI B29.1-2011 Roller Chain Standard SizesSizePitchMaximum Roller DiameterMinimum Ultimate Tensile StrengthMeasuring Load25.
For mnemonic purposes, below is another presentation of key dimensions from the same standard, expressed in fractions of an inch (which was part of the thinking behind the choice of preferred numbers in the ANSI standard):
Notes:
1. The pitch is the distance between roller centers. The width is the distance between the link plates (i.e. slightly more than the roller width to allow for clearance).
2. The right-hand digit of the standard denotes 0 = normal chain, 1 = lightweight chain, 5 = rollerless bushing chain.
3. The left-hand digit denotes the number of eighths of an inch that make up the pitch.
4. An “H” following the standard number denotes heavyweight chain. A hyphenated number following the standard number denotes double-strand (2), triple-strand (3), and so on. Thus 60H-3 denotes number 60 heavyweight triple-strand chain.
A typical bicycle chain (for derailleur gears) uses narrow 1⁄2-inch-pitch chain. The width of the chain is variable, and does not affect the load capacity. The more sprockets at the rear wheel (historically 3-6, nowadays 7-12 sprockets), the narrower the chain. Chains are sold according to the number of speeds they are designed to work with, for example, “10 speed chain”. Hub gear or single speed bicycles use 1/2″ x 1/8″ chains, where 1/8″ refers to the maximum thickness of a sprocket that can be used with the chain.
Typically chains with parallel shaped links have an even number of links, with each narrow link followed by a broad one. Chains built up with a uniform type of link, narrow at 1 and broad at the other end, can be made with an odd number of links, which can be an advantage to adapt to a special chainwheel-distance; on the other side such a chain tends to be not so strong.
Roller chains made using ISO standard are sometimes called as isochains.

How do engineering chains handle misalignment between sprockets?
Engineering chains are designed to handle some degree of misalignment between sprockets. Misalignment can occur due to various factors such as improper installation, wear and elongation of the chain, or inaccuracies in the machinery. While some misalignment is inevitable in many industrial applications, excessive misalignment should be avoided to ensure optimal chain performance and longevity.
Here’s how engineering chains handle misalignment:
- Flexible Construction: Engineering chains are constructed with flexible components such as pins, rollers, and bushings. This design allows the chain to adapt to minor misalignments without putting excessive stress on the chain or sprockets.
- Articulating Joints: The articulating joints in the chain allow it to articulate smoothly around the sprockets, accommodating minor misalignment during the rotation. This helps reduce wear on the chain and sprockets.
- Tolerance for Misalignment: Manufacturers provide specifications for the allowable misalignment between sprockets. Engineering chains are designed to handle a certain level of misalignment within these tolerances without significantly affecting their performance.
- Proper Installation: Correct installation of the engineering chain is crucial to minimizing misalignment issues. Ensuring proper tension, alignment, and center-to-center distance between sprockets can help reduce misalignment and prolong chain life.
- Regular Maintenance: Regular maintenance, including chain inspection and lubrication, can help identify and address misalignment issues early on. Promptly correcting misalignment can prevent further damage and ensure efficient chain operation.
- Alignment Devices: In some cases, alignment devices or tools may be used during installation to ensure accurate alignment between the sprockets. These devices can help improve chain performance and reduce wear caused by misalignment.
It is essential to follow the manufacturer’s guidelines for chain installation, maintenance, and alignment to optimize the performance and service life of engineering chains. Addressing misalignment issues promptly and keeping the chain in proper working condition will contribute to the overall reliability and efficiency of the machinery or equipment in which the chain is used.
Can engineering chains be used for power transmission in conveyor systems?
Yes, engineering chains are commonly used for power transmission in conveyor systems. Conveyor systems are widely employed in various industries for material handling, and they require reliable and efficient power transmission methods to move heavy loads over long distances. Engineering chains are well-suited for these applications due to their robust construction, high load-carrying capacity, and versatility.
Conveyor systems often consist of a series of sprockets and a continuous loop of engineering chain that runs over these sprockets. The chain is driven by a motorized sprocket, and as it moves, it carries the conveyed material along the conveyor’s length. The design of engineering chains ensures smooth engagement with the sprockets, enabling efficient power transmission and precise material handling.
Depending on the specific requirements of the conveyor system, various types of engineering chains can be used. For instance, for applications where cleanliness is crucial, stainless steel chains with self-lubricating properties may be employed. In environments with high corrosion potential, corrosion-resistant coatings on chain components can extend the chain’s lifespan.
Furthermore, engineering chains can be customized to fit different conveyor configurations, allowing for the design of complex conveyor systems that suit specific production processes or spatial limitations.
In summary, engineering chains are an excellent choice for power transmission in conveyor systems due to their durability, load capacity, and adaptability. They ensure smooth and reliable operation, making them indispensable in material handling and conveyor applications across various industries.
Can engineering chains be used in corrosive or harsh environments?
Yes, engineering chains can be designed and manufactured to withstand corrosive or harsh environments. When operating in such conditions, it is crucial to select the appropriate materials and coatings for the chain to ensure its durability and performance. Here are some considerations for using engineering chains in corrosive or harsh environments:
1. Material Selection: Choose materials that have high corrosion resistance, such as stainless steel or nickel-plated chains. These materials can withstand exposure to moisture, chemicals, and other corrosive agents.
2. Coatings and Surface Treatments: Applying specialized coatings or surface treatments to the chain can further enhance its corrosion resistance. Common coatings include zinc plating, chromate conversion coating, and polymer coatings.
3. Sealed Joints: Opt for engineering chains with sealed joints or special seals to protect the internal components from contaminants and moisture, reducing the risk of corrosion.
4. Environmental Ratings: Some engineering chains may come with specific environmental ratings that indicate their suitability for certain conditions. Check these ratings to ensure the chain is appropriate for the intended environment.
5. Regular Maintenance: Even with corrosion-resistant materials and coatings, regular maintenance is essential. Keep the chain clean, lubricated, and free from debris to prevent corrosion and premature wear.
6. Compatibility with Other Components: Ensure that all components in the chain system, such as sprockets and bearings, are also suitable for use in corrosive environments.
7. Temperature Considerations: Take into account the operating temperature range of the environment. Some materials may perform differently at extreme temperatures, affecting the chain’s overall performance.
8. Chemical Exposure: If the chain will be exposed to specific chemicals or substances, verify that the chosen materials and coatings are resistant to those chemicals.
By carefully selecting the right materials, coatings, and design features, engineering chains can effectively handle corrosive or harsh environments, maintaining their functionality and longevity in challenging industrial applications.

ROLLER CHAIN
Roller chain or bush roller chain is the type of chain drive most commonly used for transmission of mechanical power on many kinds of domestic, industrial and agricultural machinery, including conveyors, wire- and tube-drawing machines, printing presses, cars, motorcycles, and bicycles. It consists of a series of short cylindrical rollers held together by side links. It is driven by a toothed wheel called a sprocket. It is a simple, reliable, and efficient means of power transmission.
CONSTRUCTION OF THE CHAIN
Two different sizes of roller chain, showing construction.
There are 2 types of links alternating in the bush roller chain. The first type is inner links, having 2 inner plates held together by 2 sleeves or bushings CHINAMFG which rotate 2 rollers. Inner links alternate with the second type, the outer links, consisting of 2 outer plates held together by pins passing through the bushings of the inner links. The “bushingless” roller chain is similar in operation though not in construction; instead of separate bushings or sleeves holding the inner plates together, the plate has a tube stamped into it protruding from the hole which serves the same purpose. This has the advantage of removing 1 step in assembly of the chain.
The roller chain design reduces friction compared to simpler designs, resulting in higher efficiency and less wear. The original power transmission chain varieties lacked rollers and bushings, with both the inner and outer plates held by pins which directly contacted the sprocket teeth; however this configuration exhibited extremely rapid wear of both the sprocket teeth, and the plates where they pivoted on the pins. This problem was partially solved by the development of bushed chains, with the pins holding the outer plates passing through bushings or sleeves connecting the inner plates. This distributed the wear over a greater area; however the teeth of the sprockets still wore more rapidly than is desirable, from the sliding friction against the bushings. The addition of rollers surrounding the bushing sleeves of the chain and provided rolling contact with the teeth of the sprockets resulting in excellent resistance to wear of both sprockets and chain as well. There is even very low friction, as long as the chain is sufficiently lubricated. Continuous, clean, lubrication of roller chains is of primary importance for efficient operation as well as correct tensioning.
LUBRICATION
Many driving chains (for example, in factory equipment, or driving a camshaft inside an internal combustion engine) operate in clean environments, and thus the wearing surfaces (that is, the pins and bushings) are safe from precipitation and airborne grit, many even in a sealed environment such as an oil bath. Some roller chains are designed to have o-rings built into the space between the outside link plate and the inside roller link plates. Chain manufacturers began to include this feature in 1971 after the application was invented by Joseph Montano while working for Whitney Chain of Hartford, Connecticut. O-rings were included as a way to improve lubrication to the links of power transmission chains, a service that is vitally important to extending their working life. These rubber fixtures form a barrier that holds factory applied lubricating grease inside the pin and bushing wear areas. Further, the rubber o-rings prevent dirt and other contaminants from entering inside the chain linkages, where such particles would otherwise cause significant wear.[citation needed]
There are also many chains that have to operate in dirty conditions, and for size or operational reasons cannot be sealed. Examples include chains on farm equipment, bicycles, and chain saws. These chains will necessarily have relatively high rates of wear, particularly when the operators are prepared to accept more friction, less efficiency, more noise and more frequent replacement as they neglect lubrication and adjustment.
Many oil-based lubricants attract dirt and other particles, eventually forming an CHINAMFG paste that will compound wear on chains. This problem can be circumvented by use of a “dry” PTFE spray, which forms a solid film after application and repels both particles and moisture.

For mnemonic purposes, below is another presentation of key dimensions from the same standard, expressed in fractions of an inch (which was part of the thinking behind the choice of preferred numbers in the ANSI standard):
| Pitch (inches) | Pitch expressed in eighths |
ANSI standard chain number |
Width (inches) |
|---|---|---|---|
| 1⁄4 | 2⁄8 | 25 | 1⁄8 |
| 3⁄8 | 3⁄8 | 35 | 3⁄16 |
| 1⁄2 | 4⁄8 | 41 | 1⁄4 |
| 1⁄2 | 4⁄8 | 40 | 5⁄16 |
| 5⁄8 | 5⁄8 | 50 | 3⁄8 |
| 3⁄4 | 6⁄8 | 60 | 1⁄2 |
| 1 | 8⁄8 | 80 | 5⁄8 |
Notes:
1. The pitch is the distance between roller centers. The width is the distance between the link plates (i.e. slightly more than the roller width to allow for clearance).
2. The right-hand digit of the standard denotes 0 = normal chain, 1 = lightweight chain, 5 = rollerless bushing chain.
3. The left-hand digit denotes the number of eighths of an inch that make up the pitch.
4. An “H” following the standard number denotes heavyweight chain. A hyphenated number following the standard number denotes double-strand (2), triple-strand (3), and so on. Thus 60H-3 denotes number 60 heavyweight triple-strand chain.
A typical bicycle chain (for derailleur gears) uses narrow 1⁄2-inch-pitch chain. The width of the chain is variable, and does not affect the load capacity. The more sprockets at the rear wheel (historically 3-6, nowadays 7-12 sprockets), the narrower the chain. Chains are sold according to the number of speeds they are designed to work with, for example, “10 speed chain”. Hub gear or single speed bicycles use 1/2″ x 1/8″ chains, where 1/8″ refers to the maximum thickness of a sprocket that can be used with the chain.
Typically chains with parallel shaped links have an even number of links, with each narrow link followed by a broad one. Chains built up with a uniform type of link, narrow at 1 and broad at the other end, can be made with an odd number of links, which can be an advantage to adapt to a special chainwheel-distance; on the other side such a chain tends to be not so strong.
Roller chains made using ISO standard are sometimes called as isochains.

Ensuring proper maintenance and selecting the appropriate chain type for the specific application will maximize the chain’s performance and service life.
How do engineering chains handle angular misalignment between sprockets?
Engineering chains are designed to handle a certain degree of angular misalignment between sprockets. Angular misalignment occurs when the rotational axes of the driving and driven sprockets are not perfectly parallel, leading to an angle between them. While it is essential to minimize misalignment to prevent excessive wear and premature failure, some level of misalignment tolerance is built into engineering chains to accommodate real-world installation variations.
When angular misalignment exists, the chain’s side plates and rollers are designed to articulate and adjust to the varying angles between the sprockets. This flexibility allows the chain to smoothly engage and disengage from the sprocket teeth without binding or jamming. However, it’s important to note that excessive misalignment can still cause accelerated wear, noise, and reduced efficiency in the chain drive system.
To ensure optimal performance and longevity, it is recommended to keep angular misalignment within the manufacturer’s specified limits. These limits can vary depending on the chain size, type, and application. When installing an engineering chain, it’s crucial to align the sprockets as accurately as possible and use alignment tools if necessary.
In applications where angular misalignment is unavoidable, special chain types or accessories, such as chain tensioners or idler sprockets, can be used to help compensate for the misalignment and improve overall system performance.
In summary, engineering chains are designed to handle a certain degree of angular misalignment between sprockets, but it is essential to follow the manufacturer’s guidelines and maintain proper alignment to ensure reliable and efficient operation of the chain drive system.
How do engineering chains handle shock loads and impact forces?
Engineering chains are designed to handle a range of loads, including shock loads and impact forces, encountered in various industrial applications. Their ability to withstand these forces depends on several factors:
1. Material Selection: High-quality engineering chains are often made from robust materials such as alloy steel or stainless steel. These materials provide excellent strength and durability, allowing the chain to handle shock loads without permanent deformation or failure.
2. Chain Design: The design of engineering chains plays a crucial role in their ability to handle shock loads. The chain’s structure, such as the shape and size of its components, determines its load-bearing capacity and resistance to impact forces.
3. Heat Treatment: Some engineering chains undergo specific heat treatment processes to enhance their hardness and toughness. Heat-treated chains can better withstand shock loads and impact forces, making them suitable for demanding applications.
4. Fatigue Resistance: Engineering chains are designed to have good fatigue resistance, which means they can endure repeated loading cycles without failure. This property is essential for withstanding impact forces that occur intermittently in certain applications.
5. Proper Installation and Tensioning: Correct installation and appropriate tensioning of the chain are essential to ensure optimal performance under shock loads. Improper tensioning may lead to excessive stress on the chain and premature failure.
6. Chain Speed: The speed at which the chain operates can influence its ability to handle shock loads. High-speed operation may generate additional forces, so the chain must be rated to withstand these forces without exceeding its limits.
7. Regular Maintenance: Proper maintenance is crucial for extending the life of engineering chains subjected to shock loads and impact forces. Regular inspections, lubrication, and replacement of worn components are essential to keep the chain in optimal condition.
Overall, engineering chains are engineered to handle shock loads and impact forces in industrial environments. However, it is crucial to choose the right chain type, size, and material for the specific application and to follow proper installation and maintenance practices to ensure reliable and safe operation under varying load conditions.

Different types of drive chains
There are many different types of drive chains. You should be able to differentiate between roller chains, forged rivetless chains, double chains, flat-top chains, and helical chains by the terms used. This article will provide information on the different types of chains. Then, you can choose the right one according to your needs. If you haven’t purchased a chain yet, read this article to get started. It will also provide information on the pros and cons of each type.
roller chain
There are several differences between drive chains and roller chains, but in essence, the two are functionally similar. The choice of which type to use depends largely on the type of environment it will be exposed to. While roller chains are suitable for clean indoor environments, they are not very forgiving when it comes to rubbing against the rails. Following are the main differences between a drive chain and a roller chain. Using the correct drive chain is essential for a smooth and efficient running machine.
Roller chain drive chains come in many different weights and tensile strengths. For light-duty applications, use a smaller pitch chain. For heavy-duty applications, use larger pitch chains. The design simplicity of these chains makes them ideal for a variety of applications. While they are great for a variety of applications, the durability of these chains makes them ideal for a variety of applications. Some of the main uses of roller chain drive chains are listed below.
When replacing the drive chain, be sure to follow the safety guidelines. The most important thing to remember is not to place the chain on a dirty floor as it may cause stretch or damage. After removing the chain from the sprocket, apply the measured load specified by ANSI to it. If the load exceeds this value, the chain may bend. A suitable load for measuring a drive chain should be at least six links.
While roller chains are usually made of carbon steel, some are made of stainless steel and are used in food processing machinery. In these environments, the chain may be made of stainless steel for lubrication. Brass and nylon are also sometimes used to meet these requirements. Regardless of the application, however, choosing the right drive chain is critical to the success of a roller chain machine. It is important to maintain the proper balance between the roller chain and the machine.
To properly use a roller chain, first determine the size of the sprocket used for the drive. The size of the chain should be smaller than the smallest sprocket to prevent tooth interference and provide adequate winding on the smaller sprocket. A good practice is to choose a drive chain with a center distance of 30 to 50 times the chain pitch. The longest possible center-to-center distance is approximately 80 times the chain pitch but is not recommended for high-speed applications.
Drop forged rivetless chain
Drop-forged rivetless drive chains are made of drop-forged steel components. Their proportions are suitable for strength and lightweight. Forged rivetless chains are generally divided into three types. Each of these types has its own set of important specifications. Key topics include minimum ultimate tensile strength, chain length tolerances, and link dimensions. Read on to learn more about each type and its uses.
One of the main features of forged rivetless chains is that, despite their relatively low price, they are designed to be very durable. The quality of a forged chain depends on the structure and design of the chain. The manufacturer of this type of drive chain is CZPT, which has a large stock of these chains. The chain is proof tested after assembly and comes with a two-year parts replacement warranty.
Forged rivetless chains are available in a variety of pitch sizes and strength grades. They are made of cast manganese or alloy steel and have an average strength of 24,000 to 300,000 pounds. These chains are suitable for automotive, conveyor, and material handling as well as meat packaging, sugar processing, and steel mill applications. They are also widely used in conveying systems. To ensure quality and performance, manufacturers offer a variety of forged chains.
CZPT offers forged CZPT drive chains for fatigue-free operation. The chain includes a solid one-piece forged drive pawl for optimum durability. Chains are available in Figure 8 and in D-shape styles. For more information, please contact CZPT directly. Custom Drop-Forged rivetless drive chains can be ordered. Manufacturers also offer custom chains for specific application needs.
double chain
Duplex drive chains have two sets of rollers instead of one, producing twice the power. Double chain roller chains have pins and roller bearings, while triple chain chains have an extra row of plates to accommodate the three sprockets. They are usually interchangeable with each other. They are available for US, UK, and ISO standards. They are made of carbon steel, stainless steel, and nickel or nickel-plated.
flat top chain
Flat-top drive chains are ideal for curved or straight tracks and come in many different types and thicknesses. These chains are highly resistant to wear and are usually made of steel, stainless steel, or plastic. CZPT manufactures special brands of flat-top chains with high wear resistance and excellent noise reduction. In addition to being versatile, flat-top chains can be used in a variety of industrial applications.
There are two main types of CZPT chains: solid top or raised rib. One piece is formed from a single unit link and the other has roller base links for added strength. The two-piece chain combines flat tabletop links and a roller bottom chain for added strength. These chains are available in widths up to 20 feet and are available in a variety of widths. These chains are available in stainless steel, cast iron, or plastic.
The hinge pin is another important part of the flat top chain system. Support chain plate to ensure smooth conveying. The hinges are available in single hinge pin and double hinge pin styles. Standard hinge pins are designed for straight, narrow-width chainplates; double hinge pins are designed for longer, heavier products. The hinge pins also come in many different materials, including aluminum and galvanized steel. This allows for customization based on machine design, operating conditions, and drive method.
Whether your flat-top chain conveyor system is large or small, a high-quality flat-top chain will get the job done. With their low maintenance and low maintenance design, these chains are easy to clean and maintain. They can accommodate workpiece pallets of various sizes, and their flexibility makes them ideal for many different applications. They can also be highly customized for various industries. So if you need an industry-specific conveyor, then a flat-top drive chain is the way to go.

Three important aspects of the drive chain
One of the advantages of a drive chain is that it is relatively light. It sends nearly all of the engine’s power to the rear wheels, even if it loses some power along the way. Engine power on a dyno is different than on the road. Therefore, the chain is the most efficient way to transmit power to the rear wheel. Let’s look at three important aspects of the drive chain. Here are some facts about them.
roller chain drive
When choosing a roller chain drive, consider your application and how much horsepower your system requires. For applications requiring more horsepower, a multi-strand drive is an option. If your horsepower is limited, single-strand drives are a good choice. Otherwise, you may need to choose the smallest pitch chain. However, this may not always be possible. You should also consider sprocket size. In many cases, choosing a smaller chain pitch can increase the number of options.
While proper lubrication and maintenance can last a roller chain drive for years, regular inspections are essential to prolonging its life. After the drive has been operating for 100 hours, a thorough inspection every 500 hours is recommended. During this inspection, look for key elements such as 3% elongation and chain wear. If the chain is not preloaded, elongation will happen very quickly. In either case, the industry-recommended 3% elongation will be achieved faster.
flat top chain
The flat-top chain system consists of hinge pins that support the chain to ensure efficient conveying. There are different types of hinge pins available, namely single and double. The single hinge pin is suitable for short chainplates and lightly loaded products. Dual hinge pins provide increased stability and load capacity. Flat top drive chains can be used in many different industries. In this article, we will learn about some important properties of flat-top chains.
Plastic flat top chains can transport medium to large workpiece pallets. They have a circular arc function that enables continuous drive combinations involving curved circular arcs. Plastic flat top chains are also recommended for workpiece pallets with PA wear pads. Steel flat-top chains can withstand surface loads up to 1.5 kg/cm, and HD profiles are suitable for steel chains. This chain is used in a variety of applications, including packaging machines.
mute chain
There are several types of mufflers that can silence your drive chain. One is the Ramsay silent chain, also known as the inverted tooth chain. These chains can be custom designed for specific needs. Exclusive Australian distributor of CZPT products that can help you find the most effective and affordable silent chain. In addition to silent chains, CZPT also manufactures sprockets and other hardware required for the drive.
Another type of mute chain is the CZPT chain. CZPT chains have involute teeth, while the ANSI standard specifies straight teeth. The advantage of silent chains is reduced noise and vibration output, and wider chains are more economical than multi-strand roller chains. The downside of silent chains is that they wear out quickly without lubrication.
The mute chain consists of two main parts, the pin and the plate. The pins are rotated in the same direction and positioned so that they can only engage the sprocket from one direction. Therefore, mute links are not recommended for reverse applications. To find out if your chain will work in reverse, consult the manufacturer’s catalog. CZPT chain.
conveyor chain
Drive chains and conveyor chains are essentially the same, but they are very different. The transmission chain is mainly used to transport heavy objects, and the conveyor chain is used to transport light objects. On the other hand, drive chains are usually driven by belts. Both types of chains can be used for the same purpose. This article will cover both types of chains. You can use them to convey various types of materials and products.
There are some differences between belts and chains, but both types can perform similar functions. The drive chain is used to drive the rollers, while the belt is used to move the object horizontally. The drive chain usually drives the rollers that move the conveyor belt. For a wide range of applications, conveyors and drive chains can be customized to meet specific needs. Here are some common uses of these two chains:
time chain
Timing chains fail for two reasons: complete damage and fatigue. Fatigue occurs when a timing chain reaches its breaking strength, and eventually, failure occurs when a timing chain exceeds its design life and suffers mechanical damage. Most timing chain failures are a combination of mechanical failure and fatigue. Chain chatter, engine misfires, and VVT systems can accelerate chain fatigue. If these causes of premature timing chain failure are not addressed, the timing chain could be permanently damaged.
In the past, the timing chain was the only drive chain available. Timing belts are a quieter alternative, but they are prone to failure and damage to valves and the engine. In recent years, OEM manufacturers have begun to return to the OHC/DOHC drive chain of the timing chain. This type of drive chain has many advantages, including the ability to simulate knock sensor vibrations. Additionally, the chain has better NVH performance, making it the drive chain of choice for automakers.
Timing Chains in Internal Combustion Engines
Internal combustion engines use timing chains to control intake and exhaust valves. The chain turns the camshaft at the right time and coordinates the movement of the valves on the cylinder head. This in turn allows the engine to generate power. The timing chain also controls the position of the intake and exhaust valves, ensuring that fuel and exhaust gases are expelled at the correct time. Incorrect timing in the vehicle can lead to misfires and other problems.
Chain drives in internal combustion engines are a common feature of many modern cars. It transmits rotational force from the crankshaft to the camshaft, which in turn controls the opening and closing of valves. The chain is lubricated with oil to prevent wear. Therefore, timing chains are often used in high-capacity engines, including trucks and motorcycles. But they do have some drawbacks.
A weakened timing chain can cause the engine to misfire, causing it to skip gears and lose coordination. A clicking sound may also indicate a problem. If the chain is too loose, it can also cause the engine to stall. If the chain is too loose, metal chips will appear in the oil. A clicking sound may also be heard when the engine is running. If you hear the engine stalling, it’s likely that the timing chain is the culprit.
Silent chains in internal combustion engines
The pitch difference between the drive sprocket and the silent chain reduces resonance sound, meshing shock, and accelerated wear at the chain and sprocket interface. The difference in pitch between the drive sprocket and the silent chain determines the loudness of the sound, and the system described here helps reduce it. The present invention is suitable for power transmission in internal combustion engines.
The earliest designs for silent chains come from the 1500s when Leonardo da Vinci sketched them. The SS Britannia propels the boat across the Atlantic using huge silent chains. By the mid-19th century, silent chains were used in nearly all types of industrial applications and as timing chains for early automobile engines. Due to their durability, these chains are durable and have smooth action.
In order to understand the mechanism of frictional losses in chains, various parameters must be considered. Speed, pitch, temperature and tension are the main parameters affecting friction loss. This test uses two types of chains to compare the frictional behavior between these two components. The results show that a single chain with a high pitch can increase the friction torque of another chain with the same pitch. These results provide an important basis for understanding the role of friction torque in internal combustion engines.
lifting chain
Lift chairs are designed to lift heavy objects and can be used with a variety of lifting equipment, including forklifts and cranes. Hoist chains are also used in warehouses and ports of all sizes and consist of a series of pins and plates that mesh with each other to move heavy loads. CZPT Chain manufactures high-precision lifting chains. Here are some of the benefits of hoist chains for drive chains.
Blade Chain: This type of drive chain has a patented U-profile that turns the flexible chain into a highly stable outer post during the push phase. This design is designed to minimize linkage tangling and provide better pressure transfer. These chains are used for cranes, anchors and straddle carriers. Blade chains are more durable than other types of drive chains and are especially useful in heavy duty applications.
The drive chain is also available in a variety of materials. For example, square link chains are commonly used in cranes and hoists. They are cheap to manufacture but more prone to overloading. Conveyor chains are specially designed for chain conveyor systems. It consists of a series of interconnected rectangular links. Oval links tend to kink and are usually only used at low speeds.

What is a drive chain?
A drive chain is a wheeled device that transmits power from one gear to another. The drive chain is usually an oval ring around a corner or worm gear. On the other hand, idler pulleys do not transmit power and are not used to move the chain. In some cases, drive chains can be used with idler pulleys to transport objects. This allows the drive chain to recover some power from the second gear.
conveyor chain
There are many types of conveyor chains to choose from. One type is a closed joint chain. It consists of the barrel and connecting rod, made from a single casting and heat-treated for high strength and durability. Conveyor chains typically have low running speeds and are typically made of malleable iron. Another type of chain is the power transmission chain, which is used to transmit mechanical power. They feature efficient lubrication and are stronger than conventional conveyor chains.
Roller chain pitches can range from half an inch to a third of an inch. They are available in steel and nickel-plated steel. They can be used with inline or staggered rollers and can be designed with different pitch levels. They can also have bushings between the chainplates or gaps between the teeth to increase their maximum spacing. When choosing a conveyor chain, remember to properly lubricate bearing surfaces to minimize power absorption, wear, and corrosion. Mineral oils of medium viscosity are suitable for normal operating temperatures. SAE 20W50 is suitable. Manufacturers also offer self-lubricating chains.
Conveyor chains are used in many industries. The automotive industry has traditionally used these chains for bulk transport. Their reliability and low cost make them an excellent choice for a variety of applications. CZPT Chains offers stainless steel and CZPT conveyor chains to meet your unique requirements. If you’re in the market for a new conveyor, don’t forget to shop around. CZPT Chain can help you find the perfect one.
The regular drive version consists of an ASME/ANSI roller chain wrapped around a driven sprocket. It can also be configured for variable rpm. The gear ratio between the two parts determines the reduction or increase in speed. In some cases, solution chains can be used. Roller chains are more efficient. Then, there are solutions for both cases. There are many types of conveyor chains to choose from.
Conveyor chain pitch also plays an important role in performance. The smaller the pitch of the chain, the faster it spins. On the other hand, a smaller pitch will require more teeth on the sprocket, which means more links will be engaged during the movement. This smaller articulation angle also produces smoother motion. It also reduces vibration. Therefore, CZPT Chains can be trusted for a long time.
roller chain
The performance of a drive chain depends on how well it is maintained and lubricated. Careful attention to detail is required when selecting a roller chain, which is one of the most important components in a drive chain. Its proper lubrication and assembly will significantly affect its wear life. Here are some important tips to follow when buying a roller chain:
The size of the drive chain should be selected according to the sprockets used. The large sprocket should have at least 25 teeth, and the small sprocket should have fewer teeth. The pitch of a drive chain is the contact angle between the chain and the sprocket. The smaller the sprocket, the smaller the contact angle of the two parts. Larger sprockets are better, but smaller sprockets must never have fewer teeth.
When purchasing a roller chain, be sure to consider the maximum speed of the small sprocket. This will determine how much lubrication you need. Different lubrication systems have different requirements. Manual lubrication limits how many feet per minute the drive chain can run, while oil bath lubrication can get you up to 1100 ft/min. The only way to maximize drive chain speed is to purchase a pump lubrication system.
Once you have the right length, you can determine if you need a new one. To do this you have to move the axis to measure the length. Once the length is determined, the drive chain should be removed from the sprocket and measured using the ANSI specified measuring load. You should also follow safety guidelines when measuring your chain. If you want to maximize the life of your drive chain, be sure to follow these tips.
Another important consideration is the type of environment you operate in. For applications that need to avoid rubbing steel rails, it is best to use a roller chain that can withstand a clean indoor environment. Although roller chains are generally more durable, they must be stored properly to avoid corrosion. If you care about the environment, consider opting for double chain. Its durability and low maintenance costs will make it a valuable investment in your business.
closed pivot
Closed-end pivot drive chains are used in a variety of applications. They are known for their durability, high strength, and long life. They are available in a variety of grades, including grade 400, grade 600, and grade 800 pivots, which can withstand the high forces required for certain applications. Enclosed pivot chains can be used to lift, pull, convey and transfer heavy loads.
Class 400 closed-end pivot chain features one-piece cast offset link construction. Steel pins connect each link and are prevented from rotating by head stops. This design allows the pin to connect inside the barrel without breaking. This type of chain is the most commonly used and has the highest durability. In addition to being extremely durable, it offers long-lasting performance and smooth operation.
Another closed-end pivot conveyor chain drive is called a power drive chain. These chains consist of barrels and links used to transmit rotation from one shaft to another. The barrels of the closed-end pivot chains are made of steel, which allows them to run easily on the sprockets. Block drive chains are used for low-speed applications, but they can be noisy when the chain is in contact with the sprockets.
The enclosed pivot drive chain has rollers on both ends to minimize wear. These chains are usually made of steel and can be used in areas where high-speed power transmission is required. They are also available in heavy-duty versions. Unlike other types of chains, steel pivot chains are designed for a variety of applications. They are suitable for heavy-duty applications and their open barrel design allows for minimal contact with the pins in the barrel and the root of the sprocket.
Linear chain
CZPT is an important part of linear drive technology. This type of chain is capable of delivering real power in tight spaces. Typically, loads are moved by pulling or pushing. CZPT can perform both types of movements. They can push and pull additional loads. This type of chain can also be wound and stored in the magazine. It is a popular choice for small machine tools and many other uses.
Unlike traditional mechanical chains, CZPT uses a push-pull strategy to move heavy objects. It is a rigid locking design that prevents kinking and allows the chain to transmit force without bending. The CZPT is an excellent choice for moving large loads and is particularly versatile in power transmission. However, CZPT is more expensive than traditional drive chain options.
The service life of a linear chain depends on its design, material type and size. You may want to buy a good quality chain, but it’s not necessary in all cases. While superior quality can extend the life of the chain, it may not be necessary for low-speed drives or very light shock loads. If you’re not dealing with high-velocity shock loads, you probably don’t need features like oil reservoirs or bushing grooves.
The size of the drive sprocket can have a major impact on the overall life of the linear chain. It determines how fast the chain can go and how much horsepower it can produce. An 11-tooth chain will hit about half its rated speed, but only about 30 percent of its rated horsepower. You can extend the life of your linear chain by choosing a drive sprocket with a higher number of teeth. It is best to choose a drive sprocket with a high number of teeth, but make sure the number of teeth is even. This will ensure that your chain wear is evenly distributed.
