Types of roller chains and their applications

There are many factors that can cause premature wear of the roller chain. They include friction, external shocks, and lack of lubrication or adjustment. Here are some tips to help you prevent premature chain wear. Read on to learn more about the different types of roller chains and their applications. You’ll be surprised how quickly the roller chain wears out! Below we have listed some of the most common causes of premature roller chain wear.

Double strand heavy-duty roller chain

If your application requires a heavy-duty chain, a double-strand steel roller chain is an excellent choice. Double-strand steel roller chains are manufactured to reduce stress fatigue and stretch, making them ideal for industrial and logging equipment. This type of chain is also heat-treated and shot-peened for excellent fatigue resistance and strength. Listed below are some of the advantages of double-strand heavy-duty roller chains.
When comparing single-strand and double-strand heavy-duty roller chains, double-strand steel roller chains are generally better. They have twice as many side plates and a working load close to that of a twin-strand steel roller chain. Unlike single-strand steel roller chains, double-strand roller chains are not interchangeable with standard double-sprockets. They use sprockets specially made for double chains.
Double strand chains are particularly strong, resistant to rust and corrosion, and ideal for high-stress applications. They are commonly used in conveyor systems, paper mill equipment, ditches, lifts, seed drills, and various hoisting machinery. They are also used in the wastewater and food processing industries. Chains of this type are used on conveyor lines, so they are an excellent choice for heavy machinery.

Nickel-plated chain

Nickel-plated roller chains are ideal for outdoor work, mildly corrosive environments, and applications requiring a good chain appearance. Nickel plating increases component hardness and improves wear resistance while ensuring that all surfaces are protected. The benefits of nickel-plated roller chains include increased durability, corrosion resistance, and a bright shine. Here are a few reasons to use such a chain. All chains are manufactured to the highest quality and safety standards.
Although slightly corrosive, nickel-plated roller chains are ideal for applications in high salt and high humidity environments. However, nickel plating can peel and chip, so nickel roller chains are not recommended for use in food processing or other environments exposed to corrosive substances. ANSI B29.1 standard chain can be nickel-plated and is ideal for a variety of applications including industrial garage doors and boat lifts.
CZPT USA Corp. is committed to being the premier agricultural and industrial chain supplier in the United States. By focusing on quality, they ensure their chains provide long life and unmatched wear resistance. If you’re looking for a quality plated roller chain, consider choosing a chain from a leading manufacturer. If you need the durability and strength of a nickel roller chain, choose CZPT USA Corp. We manufacture the highest quality chains in the USA.
In addition to high strength, nickel-plated roller chains are also available in elastomer profiles. These types of chains can handle 1/2 to 3/4″ loads, depending on their pitch. They are also ideal for gentle traction on sensitive surfaces. The strength of these chains depends on the type of the main link used in the chain. Nickel-plated roller chains are available in a variety of sizes and are priced to suit a variety of applications.

Stainless steel chain

Stainless steel roller chains are ideal for industrial applications in two harsh environments. They have excellent chemical and corrosion resistance, as well as high strength. Chains are available in three grades to meet various operational needs. 304SS is suitable for food contact applications, while 316SS and 606SS offer excellent corrosion resistance. 600 series stainless steel provides excellent corrosion and wears resistance with precipitation hardened components.
In food processing, stainless steel chains are often exposed to extremely high temperatures and high concentrations of acids, alkalis, and water. They are also resistant to high concentrations of acid and chlorine. And their low magnetic permeability allows them to function properly in hygienic conditions. But stainless steel roller chains also have some disadvantages. Despite their excellent corrosion resistance, these chains are not recommended for use in food processing environments.
Compared to carbon steel, stainless steel roller chains are softer and hold longer. This means it may wear out faster. Since stainless steel is not heat-treated, its surface hardness is different from carbon steel. It retains heat for longer, reducing its tensile strength and extending its lifespan. Nonetheless, stainless steel roller chains are ideal for a variety of industrial applications.
The stainless steel roller chain is made of high-quality material. For example, the Premier series stainless steel roller chains are manufactured in Japan using a special type of stainless steel shot peening process. They also feature a solid roller design that reduces side flex. The Premier range also features highly polished side panels and is available in 10′ boxes, 50′ reels, and 100′ reels. They can also be cut to length if necessary.

Accumulation conveyor

Roller chain accumulation conveyors are designed to transport loads up to 440 lbs or 200 kg. The accumulator chain is located on large idler rollers to ensure quiet operation and the minimum force required to hold the pallet. They are suitable for various applications and can be integrated into the entire processing system. These conveyor belts have T-slots on three sides of the profile frame for connecting brackets and sensors.
Sensors installed in the accumulation area detect objects on the conveyor line and send signals to the motors that power the accumulation area. The motor can be external or built into the drum itself. Other types of sensors use light, such as photosensors. Photoelectric sensors detect objects by emitting and receiving specific wavelengths of light. This option is cost-effective because the sensor rollers are located slightly above the surface of the conveyor line.
Roller chain accumulation conveyors can be constructed of steel or plastic rollers. It can be equipped with staggered or coaxial rollers. Safety cover prevents accidental insertion of fingers into the chain, improving operator safety. The safety cover is compatible with the chain type and required bend radius. These caps are made of plastic clips that fit permanently on the inner links of the chain. They do not interfere with conveyed goods or workpiece carriers.
There are two basic types of accumulation conveyors: free flow and accumulation. Free-flowing chains allow conveyed objects to slide directly onto the chain while stacking chains allow goods to slide under the chain. Accumulation chains are commonly used in the food and packaging industries and have rollers that support conveyed objects. The free-flowing conveyor system eliminates the risk of damaging objects, as the rollers in the accumulation conveyor are in direct contact with the bottom of the cargo.

Custom attachment

Standard accessories for roller chains are available in a variety of styles. Typically, they can be assembled on pin or roller links. When referring to connecting chains, it is important to know how to refer to pitch and center-to-center spacing. The pitch of the roller chain should include inner and outer roller links and must alternate every three pitches. Additionally, you can order custom accessories for pin or roller linkages. Below are some examples of custom accessories for roller chains.
Stainless steel roller chains are one of the most well-known chains for this application. It has a stainless steel 304 finish to create curved and straight lugs. For even more flexibility, you can also request custom accessories such as chain plate holes and pins. For added safety, various accessories can be attached to the single-pitch roller chain. It can also be made with multiple pins or curved lugs.
HKK Chains is stocked with much stainless steel and carbon steel standard connecting chains. Most of the time, they can assemble a custom accessory chain in no time. For example, a single-pitch chain with two connecting holes is called a wide profile. Additionally, chains can be manufactured in a variety of materials, including carbon steel, stainless steel, Lambda, plastic, and Ultra WP. In addition, a wide range of unique accessories is available for special industries.

The impact of put on on a roller chain is to increase the pitch (spacing of the links), leading to the chain to expand for a longer time. Notice that this is because of to wear at the pivoting pins and bushes, not from genuine stretching of the metallic (as does occur to some adaptable metal elements this kind of as the hand-brake cable of a motor motor vehicle).
With CZPT chains it is abnormal for a chain (other than that of a bicycle) to put on until finally it breaks, given that a worn chain prospects to the fast onset of use on the tooth of the sprockets, with final failure becoming the loss of all the tooth on the sprocket. The sprockets (in specific the smaller of the two) undergo a grinding motion that places a characteristic hook form into the driven encounter of the tooth. (This impact is made worse by a chain improperly tensioned, but is unavoidable no issue what treatment is taken). The worn tooth (and chain) no longer provides smooth transmission of electricity and this may possibly grow to be evident from the sound, the vibration or (in automobile engines making use of a timing chain) the variation in ignition timing observed with a timing light. Each sprockets and chain ought to be replaced in these situations, since a new chain on worn sprockets will not last prolonged. Nevertheless, in significantly less severe instances it may be feasible to save the greater of the 2 sprockets, given that it is often the scaled-down 1 that suffers the most put on. Only in quite mild-fat programs these kinds of as a bicycle, or in severe circumstances of poor rigidity, will the chain normally soar off the sprockets.

The lengthening due to use of a chain is calculated by the pursuing method:

M = the duration of a number of back links calculated

S = the amount of back links measured

P = Pitch

In sector, it is typical to check the motion of the chain tensioner (whether manual or automatic) or the precise duration of a drive chain (one particular rule of thumb is to exchange a roller chain which has elongated 3% on an adjustable push or 1.5% on a fixed-center travel). A simpler method, specifically appropriate for the cycle or motorcycle consumer, is to attempt to pull the chain absent from the greater of the 2 sprockets, even though ensuring the chain is taut. Any significant movement (e.g. producing it possible to see by way of a gap) possibly indicates a chain worn up to and beyond the limit. Sprocket harm will consequence if the dilemma is disregarded. Sprocket wear cancels this effect, and may mask chain dress in.


The light-weight chain of a bicycle with derailleur gears can snap (or relatively, appear aside at the aspect-plates, because it is typical for the “riveting” to are unsuccessful first) since the pins inside of are not cylindrical, they are barrel-shaped. Make contact with in between the pin and the bushing is not the typical line, but a point which allows the chain’s pins to perform its way via the bushing, and last but not least the roller, in the long run causing the chain to snap. This sort of building is required because the gear-modifying action of this kind of transmission needs the chain to the two bend sideways and to twist, but this can happen with the versatility of these kinds of a narrow chain and relatively large free of charge lengths on a bicycle.

Chain failure is much considerably less of a problem on hub-geared programs (e.g. Bendix 2-pace, Sturmey-Archer AW) given that the parallel pins have a much bigger donning surface in speak to with the bush. The hub-equipment system also makes it possible for comprehensive enclosure, a great help to lubrication and security from grit.


The most typical measure of roller chain’s energy is tensile energy. Tensile power signifies how much load a chain can endure underneath a one-time load prior to breaking. Just as essential as tensile toughness is a chain’s fatigue energy. The essential elements in a chain’s exhaustion power is the top quality of metal utilized to manufacture the chain, the heat remedy of the chain elements, the high quality of the pitch gap fabrication of the linkplates, and the kind of shot additionally the intensity of shot peen protection on the linkplates. Other variables can contain the thickness of the linkplates and the design and style (contour) of the linkplates. The rule of thumb for roller chain functioning on a continuous travel is for the chain load to not CZPT a mere 1/6 or 1/9 of the chain’s tensile energy, depending on the variety of master links utilised (press-suit vs. slip-suit)[quotation needed]. Roller chains operating on a continuous generate outside of these thresholds can and normally do fail prematurely via linkplate exhaustion failure.

The common bare minimum final toughness of the ANSI 29.1 steel chain is 12,500 x (pitch, in inches)2. X-ring and O-Ring chains greatly decrease dress in by indicates of inside lubricants, escalating chain lifestyle. The interior lubrication is inserted by means of a vacuum when riveting the chain with each other.


Standards companies (this kind of as ANSI and ISO) maintain specifications for layout, dimensions, and interchangeability of transmission chains. For instance, the pursuing Desk exhibits information from ANSI common B29.1-2011 (Precision Power Transmission Roller Chains, Attachments, and Sprockets) designed by the American Culture of Mechanical Engineers (ASME). See the references[8][9][10] for added data.

What is a roller chain?

What is a roller chain? A roller chain is a transmission technique that transmits power from 1 shaft to another. Interior lubricant will help chains very last longer and are interchangeable. Chains are typically made of carbon or alloy metal. Stainless steel is sometimes used in meals processing equipment or in environments in which lubrication is problematic. Brass and nylon are also occasionally used. If you require to gradual down the device, nylon chains can be utilized.

Roller chains are utilised to transmit energy from one shaft to another

Typically speaking, the life of a roller chain is restricted by a few principal factors: wear, corrosion, and exhaustion. These can be minimized by following some easy suggestions. For ideal performance, the roller chain must be lubricated. Suitable lubrication minimizes friction and extends merchandise daily life. Remember that corrosion and wind resistance can adversely impact lubrication, so defend the solution appropriately.
A chain is a mechanical system utilized to transmit power from a single shaft to another. The chain consists of a series of metal plates named bushings. Bushings are attached to the roller chain by pins or bushings. The block and bushing are held with each other by pins or bushings C riveted to the outer hyperlink D. The chain is also hooked up to the sprocket and bucket by pins or hooks. Chain pitch is calculated amongst hinge centers, normally denoted p.
There are a few types of chains: one-strand normal series, multi-strand standard collection, and silent chain. Solitary strand chains are the most typical variety and include a extensive variety of generate masses. Multi-strand chains supply increased power potential with no growing chain pitch or line pace. An inverted tooth chain is a variant of a solitary-strand chain that gets rid of the sound induced by pitch-related friction.
The inner and outer plates of the roller chain push are produced of metal. The rollers are positioned evenly in between the chain links and are fixed to the sprockets. In addition, the rollers can rotate freely within the bushing. The chain back links are arc-formed and mesh with the sprocket enamel to transmit power by means of the chain.
Chain drives are an additional widespread way of transmitting mechanical energy. These are the simplest varieties of electricity transmission and are used on conveyor belts and other minimal-speed programs. The chain wraps all around the sprocket and passes by way of the sprocket whose enamel mesh with the links. This mechanism transfers mechanical electrical power from 1 shaft to another, rising velocity.

They are interchangeable

There are numerous different types of roller chains, but most are made of steel. Even though they have their own benefits and features, they are usually interchangeable. You can acquire diverse kinds of roller chains from domestic and overseas makers, and you can choose the one that very best fits your demands. Bearing Services can assist you pick the proper bearing for your software wants and budget. Right here are some important factors to take into account prior to acquiring a roller chain. Right here are some suggestions to make it less complicated for you to acquire the right type of chain.
When selecting the proper roller chain, be certain to seek the advice of the obtainable measurement charts. Relies upon on how a lot chain you want to transfer the load you need to have to transfer. Keep in mind that roller chains can be made to in shape a selection of machines and need to fulfill your distinct demands. Also, the chain need to be long adequate for the machine you are making use of. Make sure to buy a chain created of high-quality materials.
Double pitch roller chains have a flat leading surface and are utilised in numerous various conveying programs. Double-pitch load-carrying roller chains, also identified as outsized roller double-pitch chains, have rollers that extend beyond the sidebars to carry items. Double pitch travel series roller chains are utilised in elevators, lengthy conveyor drives, agricultural equipment, and business sprinkler systems.
The tensile toughness of a roller chain is a important aspect to think about before buying a chain. The tensile strength of a chain is a function of the highest force the chain can withstand ahead of breaking. The a few diverse kinds of tensile power symbolize the pressure a chain can withstand with no breaking. Each chain also has diverse strengths that can establish the variety of chain you need to have.
The outer and interior backlinks of the roller chain are designed for bearings. This makes it possible for the chain to be paired or unpaired with its internal hyperlinks. The outer website link has a pin, and the inner and outer pins are press-match into the connecting plate. These links are generally produced of steel and have a tensile toughness of about twenty instances their excess weight. The tiredness toughness of two-pitch offset hyperlinks is the very same as that of the foundation chain.

They reduce put on with inner lubricants

In a roller chain, the pins and bushings rotate inside of the chain with no lubricant on the outside. They are in get in touch with with the enamel of the sprocket and can very easily dress in out if not lubricated. The plates that link the backlinks and pivot about the pins can also rub towards every single other and cause dress in. This is exactly where lubricants occur in handy. Without having lubricant, the bare metal of the plate and bushing would rub from each and every other.
The lubricant should have the appropriate viscosity to penetrate critical internal surfaces and type an efficient oil movie. Advisable viscosities are listed in Table 1. Lubricants must be thoroughly clean and non-corrosive. For roller chains, a very good quality non-clean petroleum base oil is sufficient. Although defoamers are not needed, other additives this kind of as antioxidants and excessive stress inhibitors might be beneficial. However, impure oils need to be averted because of to the risk of hurt.
The condition of the spray head ten overlaps with a standard push chain 12. The generate chain contains a plurality of rollers 24 and roller website link plates 26. Each and every roller contains a roller pin 29 and is linked to a pair of pin url plates 28. Most travel chains have crucial dress in factors on the sides of the roller pins 29. The condition of the spray head ten helps prevent overspray on to the central part of the roller.
In addition to preventing put on, these chains have distinctive technical specs. Maker CZPT demands raw material suppliers to certify that their products satisfy specifications established by the American Culture of Mechanical Engineers (ASME). CZPTs do not settle for uncertified raw supplies. For security, the equipment should be turned off just before making an attempt to evaluate the chain. Soon after the program is shut down, the measurement approach need to be completed in accordance with safety methods.
Standard spray oil has lubricating qualities, but is not as great as other sorts of chain lubricants. These are typically utilized for rust security and incorporate antioxidant substances. Normally, they are inexpensive and broadly offered in retail retailers. Even so, they have the disadvantage of being extremely penetrating and challenging to use evenly. Oil can’t stay on the chain as it spins, which can accelerate put on and corrosion.

They can be utilized to pace up or slow down machines

Usually, roller chains are chains utilized to shift mechanical method components. In contrast to belts, roller chains can be utilised to pace up or gradual down a machine. The main difference amongst belts and roller chains is the lubrication method. Belts use lubrication to help them move at a continual velocity, but need to not exceed the essential velocity of the roller chain. This crucial speed is not straightforward to establish and lubrication is essential to its existence.
A roller chain is a chain consisting of a steel bushing that retains the inner plate A and pins C jointly. Pin C is riveted to outer website link D, whilst roller R surrounds each bushing B. The teeth of the sprocket are supported on the rollers. They spin freely on pins and bushings, minimizing friction.
The chains can be one-stranded, double-stranded, or multi-stranded. The rated power capacity of the single strand chain can fulfill a variety of travel load specifications. Multi-strand chains give larger power capacity with no rising chain pitch or line speed. The silent chain, also acknowledged as the inverted tooth chain, is composed of a series of toothed chainplates. The pins of the chain are pressed into the wide finishes of the sidebars and outer hyperlinks.
Although roller chains are a common mechanical element, they can fall short under particular situations. The most widespread trigger of abnormal wear is incorrect to load sizing. Each company sets a maximum workload for its product. A chain that is as well little for the load carried will not operate efficiently and might lead to premature failure. Chains can also fail due to rust or incorrect servicing.
There are several ways to select the right size roller chain. The simplest way to choose the right 1 is to use a horsepower chart to figure out the speed of the motor. RPM will determine the measurement of the chain and the amount of enamel on the push sprocket. Conveyor chains provide a range of possibilities to shift products horizontally or vertically, even close to bend radii.
