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.

The roller chain of the drive chain must be properly tensioned. It should also have a proper lubrication system. Chain sag should not exceed two to four percent of the center distance (the distance between the two axles). Also, it shouldn’t make any unusual noises or obvious problems. One of the main reasons for excessive wear is the size of the load. Each chain has a specified maximum working load.
The maximum roller chain load must be less than 1/9 or 6 times the tensile strength of the drive chain. This amount should not exceed this threshold, as exceeding this level will result in chain plate fatigue. To avoid this, you should use a roller chain with a higher number of strands. Also, for high power requirements, a roller chain with a higher number of strands is recommended. One final tip for choosing a drive chain: it should not be used when there is a high risk of corrosion or rusting.
The materials used to manufacture roller chains vary according to the specific application. Common materials include steel and stainless steel. However, stainless steel is used in food processing machinery and other environments that require lubrication. Brass and nylon are also sometimes used. These factors determine the selection of suitable materials for the drive chain. If you are not sure which material to use, you can consult an industry professional. These professionals will help you choose the right chain for the job at hand.
mute chain
The design of the silent transmission chain is as follows: the large chain plates 2 are stacked one on top of the other in the direction of the chain length. The connecting rods are connected by connecting pins 3. The outermost and central guide plates 4 are fastened to the connecting pins 3 by means of rivets. This construction helps minimize friction on the sliding surfaces of the chain. Chainplate 2 of the silent transmission chain is usually made of stainless steel.
The link plates are made of steel and have a rectangular shape with pinholes 41. These guide plates have no teeth but have curved surfaces that guide the silent drive chain on the sprockets. In addition, the rear portion of the guide plate is higher than the portion of the chainplate. This feature improves pitch balance. The present invention is also applicable to silent transmission chains using rockers.
When it comes to chain design, it’s important to remember that silent drive chains are often used in automotive engines, especially timing and cam drives. This type of drive reduces noise and vibration due to its low engagement angle and links engagement with the sprocket. However, these applications are not limited to timing and cam drives; they can also be used for front-wheel power transmission. For example, silent drive chains are designed to resemble those used in NASCAR racing engines.
The design of the silent drive chain is based on the structure of the roller chain. Its components are standardized and manufactured according to pitch. There are single-row and multi-row versions. Quiet chains, also known as inverted tooth chains, are shaped to reduce noise from stretching. It’s also designed to minimize the amount of friction caused by small changes in pitch. Its teeth don’t slide against each other, so the chain is smoother and more durable.
flat top chain
One of the important parts of the flat top chainplate system is the hinge pin, which is used to fix the chainplate and is responsible for the smooth and efficient conveying of the chainplate. There are several types of hinge pins, including single hinge pins and double hinge pins. The single hinge pin is suitable for the chainplate with a small span and small bearing capacity, and the double hinge pin is suitable for the chainplate with a large span and high bearing capacity.
The side bending flat top chain is suitable for conveying large and medium workpiece pallets. They can be made of steel or plastic, each with its own advantages. Both chainplates are designed to convey material smoothly. Side curved flat-top chains can be used on straight conveyors. They have a low coefficient of friction and can transport weights up to 1.2 kg/cm. They can also be combined with HD profiles.
Flat top drive chains are usually made of plastic material and come in two types: tabletop chains and buffer chains. They come in a variety of widths, but the most popular are standard widths, ranging from 3.25 inches to 12 inches. MatTop chains are usually shipped in 10-foot lengths. They come in different styles, but they all have the same basic specs. Tabletop chains are designed for general conveying, while pad chains are used for specific applications. Solid top chains are suitable for conveying bulk materials, while wide pad chains can handle large volumes of fluids and/or solid-solid mixtures.
These chain conveyors can be used to convey, connect or lift small items. This type of chain is especially useful in industries where the product is hot or greasy. The modular design of these chains allows them to be configured in three dimensions, making them suitable for production changes and transitions. They also help reduce slack in the chain. Flat top chains are commonly used in final assembly and mechanical or paint restoration in the automotive industry.
double chain
Besides the roller chain, another type of chain drive is the double drive chain. This type of chain consists of a series of short cylindrical rollers connected together by side links and driven by gears called sprockets. This type of chain is very reliable and only requires a tractor with a high rpm PTO. It is manufactured by CZPT and is available in many different sizes and finishes.
Self-lubricating chain
Self-lubricating drive chains are the ideal solution for applications that do not require the relubrication of conventional chains. This maintenance-free roller chain features fully heat-treated components that increase the chain’s fatigue resistance and strength. It’s sintered alloy bushings are oil-impregnated, reducing the chance of premature wear and elongation. Its self-lubricating properties enhance its durability and work well even in hard-to-reach places.
CZPT self-lubricating roller chains feature preloaded sintered steel bearing pins and oil-impregnated sintered bushings. These chains are drop-in replacements for standard roller chains and run on the same sprockets as standard chains. In addition to being maintenance-free, self-lubricating roller chains are compatible with most existing sprockets and are ideal for demanding applications.
The O-ring chain concept was used to develop self-lubricating systems. It has two or more annular grease storage chambers. A self-lubricating bushing roller chain has an oil reservoir between its pin chain and the roller chainplate. A grease seal between these two plates isolates the moving parts and keeps the joints well lubricated. O-rings are made of special nitrile rubber, whose properties vary by application.
CZPT SLR conveyor chains and CZPT SLR drive chains have rollers on sintered bushings. CZPT SLR chains and SLR conveyor chains are self-lubricating and have a higher working load than standard ANSI chains. They may not be interchangeable with other self-lubricating chains from other manufacturers. Self-lubricating drive chains are the best solution for demanding industrial applications requiring heavy-duty, reliable conveying.

To understand the competitive landscape of the Oil Field Roller Chains market, the strengths and weaknesses of each leading manufacturer must be analyzed. One of the key measurements of a roller chain is tensile strength, which determines the ability to withstand a one-time load before breaking. Fatigue strength, on the other hand, represents the maximum load that a chain can withstand over a long period of time. By comparing these two performance metrics, you can determine the best brand and type for your specific requirements.
Application of roller chain
A roller chain is a simple mechanical power transmission system consisting of a series of short cylindrical rollers connected together by side links and driven by gears called sprockets. This simple, reliable, and efficient system is commonly used to convey materials and is ideal for many different applications. This type of chain is widely used in conveyors and bucket elevators and is available in a variety of power ratings and designs.
The most common drive chains are the single-strand standard series with power ratings ranging from 0.5 to 100 kW. Alternatively, the multi-strand model is a higher performance alternative that offers higher power capacity without increasing chain pitch or line speed. The other is the silent chain, also known as the inverted tooth chain. It is designed to be noiseless and to eliminate the negative effects of stretching. It rides on the teeth of the sprocket and its radius increases as it moves. It automatically corrects slight pitch changes. It also provides smooth, long-lasting service that runs smoothly.
A roller chain consists of 5 basic components: bushings, rollers, and pins. Each individual link is held together with a pin or bushing. The pin goes through a bushing in the inner link to prevent rotation. The advantages of roller chains make them one of the most efficient power transmission and conveying options. CZPT prides itself on its knowledge and experience in roller chain applications. Below are some common uses of roller chains.
Certain applications require less than ideal roller chain performance. To meet these challenges, manufacturers offer a variety of options. A self-lubricating chain can be used to keep the chain clean and reduce dust. Oil-contaminated chains can also be used for special applications. Other materials, such as stainless steel, can help retard corrosion and improve the wear resistance of the chain. Additionally, they can be used in a variety of environments, such as food processing machinery.

How to choose a drive chain
The process of manufacturing a drive chain starts with bushing. Both inner and outer diameters are strictly measured to ensure tight tolerances. The roundness of the bushing is critical as irregular surfaces in the contact area can cause accelerated wear and shorten chain life. That’s why the CZPT manufacturing process is carefully designed to optimize the wear performance of the chain. There are several types of bushings including roller, forged rivetless, flat top, and timing.
roller chain
The tensile strength of a roller chain is the number of pounds it can withstand before breaking. Fatigue strength is equally important, although the two do not necessarily go hand in hand. Fatigue strength depends on several factors, including the quality of steel used in manufacturing, the quality of the pitch holes, the type of shot peening used, and the thickness and design of the link plates. Here are some things to consider when choosing a roller chain for a drive chain.
When sizing a chain, first determine how much power will be delivered. Then, determine how many teeth you need for the drive sprocket. The gear ratio is approximately 2:1. The number of sprocket teeth depends on the size of the motor. A chain with a higher tooth count requires fewer teeth than a smaller chain. The size of the drive sprocket also depends on the horsepower of the motor.
Before installing rollers or conveyor chains, make sure the drive system is properly aligned. If the drive chain is misaligned, the load on other components will be uneven. This can cause excessive wear on the sprocket or roller chain. Also, check that the sprocket is as close to the bearing as possible. Connecting links can be secured using openings or spring clips.
Different manufacturing processes can affect the performance of the roller chain. Some manufacturers have chains pre-installed at the factory to minimize initial stretch. Others build chains by preloading sprockets and ensuring consistent precision heat treatment. The final product may have greater elongation or less wear than previous products. It is best to follow the manufacturer’s recommendations to extend the life of the roller chain. If you are interested in purchasing a new drive chain, please contact a trusted supplier in your area.
Drop forged rivetless chain
Forged rivetless drive chains are ideal for applications where flexibility and strength are critical. The chain consists of forged steel components for high strength and lightweight. These chain assemblies are easy to assemble without the use of tools and are commonly used on carts, assembly lines, and drag conveyors. They are also compatible with related chain, drive, and accessory products. They have a short turning radius and therefore high flexibility and strength.
The X-348 Forged Rivetless Chain is an example of such a drive chain. This chain is perfect for automated machines that run late at night. It is available in a variety of weight limits and sizes. The chain is pre-stressed after assembly, and a two-year parts replacement warranty is standard. Its durability is also enhanced by the inclusion of push dogs that engage the front floating dogs on the leading free cart.
In addition to this type of chain, CZPT also offers a full line of Caterpillar Drive chains. They are designed to provide fatigue-free operation. The drive jaws are one-piece forged induction hardened steel compatible with forged rivetless chains. There are many special custom chains to choose from. These forged chains can be installed on Caterpillars as well as other types of tractors for maximum durability and efficiency.
Distributors of forged chain products offer a variety of sizes, pitches, and materials for material handling and conveying systems. Typically, this type of chain is used in conveyor and lifting applications and ranges from 3 inches to 9 inches. Depending on size and thickness, it is ideal for a variety of industries including automotive, food, paper, and steel mills. In addition, the chain is corrosion-resistant and corrosion-free.
flat top chain
The flat-top drive chain is used for conveying large and medium workpiece pallets. These chains are available in a variety of materials and designs, including plastic, steel, and stainless steel. The steel flat top chain provides high wear resistance and excellent noise reduction. Steel flat-top chains are suitable for applications requiring high loads and excellent workmanship. HD profiles are compatible with steel flat-top chains and are highly recommended for extreme applications.
CZPT produces two types of flat-top chains. Tabletop chains are similar to wing door hinges, while MatTop chains are assembled using full-width pins. Both types are available in standard widths of 3.25 to 12 inches and are shipped in 10-foot sections. Both types can be shaped according to the width of the chain.
Double hinge pin flat-top chains are available with a variety of hinge pins. There are TAB and standard hinge pins for different machines and drive methods. A flat-top chain with dual-hinge pins will provide higher load carrying capacity, but be aware of the hinge pin size and style required for your application. The hinge pins should be long enough to ensure a smooth and smooth delivery. Double hinge pin flat top drive chains are available in a variety of sizes and designs.
Using standardized components and modules, the flat-top chain conveyor system is highly adaptable and can be seamlessly integrated into any production process. It can also be extended to handle a wider range of containers. Using a single drive, the CZPT system can be extended to a length of 40 meters. Its versatility makes it the choice of many industries. There is also a wide variety of flat-top drive chains to choose from.
time chain
The drive chain is a critical component of any internal combustion engine. They transmit the rotation of the crankshaft to the camshaft via the timing chain. These chains have been standard in cars since the turn of the 20th century, and while toothed belts have become a more cost-effective alternative, manufacturers such as Mercedes-Benz and BMW remain loyal to traditional chain drives.
Timing chains come in many shapes and sizes, with different designs depending on the type of load they must carry. Roller chains are the most common and offer an excellent balance of strength and NVH performance. Its design is similar to a bicycle chain, and the inner link consists of two blades pressed into the holes of the sprocket. Roller chains can also pass through smaller diameter sprockets, and roller chains take up less space than chain links.
The length of the chain allows it to stretch over time. In addition, improper oil maintenance can lead to premature timing chain damage. Without an oil change, the chain is not lubricated, causing the rollers and links to rub against each other. This can cause excessive chain wear and eventually chain breakage. To avoid premature timing chain failure, it is advisable to have your vehicle inspected by a mechanic.
For automotive timing chains, the CZPT website offers the best prices for the timing chain you need. You can find the right timing chain for your car by registering on this website. You can also contact a mechanic to get the parts you need. If you don’t know how to diagnose your timing mechanism, you can always check the owner’s manual or the manufacturer’s website. It is critical to follow the manufacturer’s recommendations to avoid catastrophic failure.
Oil-impregnated bushing
Oil-impregnated bushings for drive chains are an excellent solution to drive chain lubrication problems. Usually, drive chains require additional lubrication, but by adding special oil-impregnated bushings, the chain can run without lubrication. Oil-immersed bushings, such as those of the CZPT brand for CZPT, are specially manufactured for this purpose. They capture oil during operation and release it onto the bearing surfaces, returning it to the bushing by capillary action.
Since their introduction to the automotive industry, engineered composite plastic bushings have been shown to provide longer service life and save up to 40% in maintenance costs. They have replaced bronze in thousands of applications, including pumps, medical equipment, and food processing machinery. Because oil-impregnated bronze bearings rely on capillary action, they must rotate to maintain a complete lubricating film. However, several factors prevent this film from fully forming, including low speeds and intermittent use.
During the manufacturing process, oil-impregnated bushings are manufactured to meet the wear resistance requirements of the drive chain. The sintered density of the oil-impregnated sintered bushing determines its mechanical strength. The larger sintered density increases the wear resistance of the oil-impregnated bushing but reduces the mechanical strength.
Whether or not a drive chain is lubricated will determine its overall life. Proper lubrication can extend chain life by 100% compared to a chain without proper lubrication. Proper lubrication means using high-quality oils without additives and oils that flow freely at prevailing temperatures. Indirect heating is required by immersing the drive chain in the molten pool as certain additives prevent oil from entering the chain joint.
