How to choose a roller chain for a conveyor

When choosing a roller chain for your conveyor, the easiest way is to refer to the horsepower and RPM charts. The horsepower and rpm of the small drive sprocket will determine the size and number of teeth of the chain. Conveyor chains are available in a variety of options, including moving products horizontally, vertically, or around a bend radius. When choosing a conveyor chain, consider the purpose of the chain. For example, if you’re delivering products to customers’ doorsteps, you might choose chains that can move products up and down a hallway or warehouse.

Double pitch

Double pitch roller chains are a popular way to drive agricultural equipment. It has twice the pitch of a standard roller chain and is ideal for light-duty drives. Extended pitch increases performance at lower speeds, but requires fewer components per foot than standard single-pitch chains. Compared to single-pitch roller chains, double-pitch chainplates are longer and are suitable for lighter loads. Read on to learn more about double pitch chains and how they can improve your operation.
The most common type of conveyor chain is double pitch. It is used in the auto parts industry, as well as in the precision machinery industry. It is made from the same components as the standard drive roller chain, except it has longer side plates. Double pitch chains are often used on slow-moving conveyors to reduce the stress placed on them. Industries that commonly use double pitch conveyor chains include airport equipment manufacturers, lumber mills, and fruit packing plants.
RS series roller chains are manufactured from high-quality stainless steel. It has excellent chemical and abrasion resistance and is available in a variety of cord lengths. RS sprockets have over 30 teeth. They contain all the necessary connection links for easy installation. PEER Chain offers double pitch roller chain attachments including pre-stretched chains, sprockets, and other attachments.
Double pitch roller chains have several advantages over standard chains. Double pitch chains have double the pitch, making them ideal for conveying applications such as conveyors. In addition to that, it also provides ANSI-compliant styles. These chains also have free connection links. When shopping for a double pitch roller chain, be sure to choose the one that fits your requirements and budget. They will last longer and save you money in the long run.
Double pitch roller chains to ANSI standards feature oversized rollers. These chains are best suited for applications where the product is mounted on top of the chain. They are ideal for agricultural applications where cotton is on top of the drum. Also, this type of chain is used in light-duty conveyors and agricultural applications. You can find double pitch roller chains in a variety of sizes and styles. And, as long as you know what you want, you’ll be happy with the results.

Self-lubricating

Self-lubricating roller chains eliminate the need for manual relubrication, providing long-lasting operation and reducing maintenance costs. These chains are particularly popular in industries such as the food and beverage industry, textiles, printing, and sawmills. They can also replace standard roller chain drives and conveyor chains. Manufactured to the specific standard ISO R606, these chains are ideal replacements for conventional chains. PC chains are particularly beneficial for food and beverage production and packaging applications due to their anti-corrosion properties.
Self-lubricating roller chains meet ISO, ASME/ANSI, and DIN standards. They are interchangeable with standard chains of the same size and shape and can be used in a variety of industrial applications. Self-lubricating chains have special oil-impregnated sleeves to reduce maintenance time. These chains are also suitable for applications where cleanliness is an issue.
Self-lubricating roller chains are manufactured with unique RS attachments. Rather than a traditional roller chain with an external lubricating ring, this type of chain retains the lubricant within its bushings. During operation, the application generates heat, heating the lubricant, which flows out of the pin and bushing area. Therefore, CZPT roller chains are ideal for certain food conveying applications.
In addition to self-lubricating roller chains, carbon steel, stainless steel or nickel-plated steel are also available. Self-lubricating roller chains are available in different sizes depending on the application, including 0.375″ wide profile straight-chain, extended pin chain, and four-link. In addition, these chains are also available in ANSI and BS chain specifications.

Accumulation

Whether you need to move large or small loads, accumulating roller chains are a viable solution. This chain conveyor is designed with low back pressure to transport large and bulky items with minimal noise. Free-running rollers within the chain help create a smooth build-up surface. These chains are available in a variety of options, including accumulating rollers of different pitches.
The accumulation and release roller chain 14 includes an upper part 15 and a lower part 16. The upper part 15 rests in the upper subspace 28, while the lower part 16 rests on the top side 20 of the profile. As the upper belt 15 rolls around the accumulation roller chain 14, it aligns with the lower chain 16 to form a continuous receiving space. This arrangement allows the accumulation roller chain 14 to rest on the top surface of the support profile 11.
A cumulative roller chain consists of many individual parts. Each section of the chain has an elongated cylindrical shape and is connected to each other by hinged joints. Each chain section also has an accumulation and release roller associated therewith. Each roller protrudes from the upper side 20 and the lower side 21 of the chain portion. The accumulation rollers are movable about an axis 22 extending transversely to the longitudinal axis of the chain.
A feature of the stacking and releasing roller chain is its simplicity. The conveyor has a profiled section that is permanently divided into two cross-sectional spaces. The bottom space is closed from all sides. The upper space accommodates the conveyor line. The contoured portion includes an opening that guides the bottom strap. A shunt can also be inserted between the two sections. The accumulating roller chain system is a convenient and versatile way to move bulky items.
There are many different types of accumulating roller chains. Some chains have offset rollers for optimal load distribution. Others have protection to prevent machine wear. Some run without lubricant, which is a safety advantage. In addition to protection, cumulative chains can also provide protection. The side bow version of the accumulation and release roller chain with offset accumulation and release rollers is designed for conveyor systems with very small bend radii.

Without bushing

Bushless roller chains are the most common type of industrial chain. They are simple in design and require only regular maintenance. Regular maintenance includes lubricating, assessing wear, and replacing worn sprockets. For more information, please read the following information:
The outer chainplates and the inner chain plates are alternately arranged in pairs. The connecting pin extends through the hole in the inner link plate. The rollers thus positioned can be rotated on the connecting pins. Oil provided between the outer circumferential surfaces of each connecting pin serves to lubricate the chain. This system reduces noise and wears caused by collisions between inner chain plates and sprockets.
Compared to traditional roller chains, bushings roller chains have rollers around the bushing. These rollers are in rolling contact with the sprocket teeth, providing low friction and excellent wear resistance. To ensure smooth operation, bushings roller chains must be greased to prevent rust and keep the chain properly tensioned. Lubricated chains run smoother and last longer.
In a bushingless chain, the inner links are shaped like half bushings and ride on the rollers. The pins go through the outer plate and connect the inner links to the rollers. The outer plates overlap the inner links and open the pins. This system is also known as a heterochain. This type of chain is more common than traditional roller chains. If you are not sure which type of bushingless roller chain to choose, you may need to purchase an additional pair of inner chainplates.
Linerless roller chains may also include chain guides. In a bushingless roller chain, the outer and inner link plates conform to the surfaces of the guide rails. Thus, the large area of contact between the chain and the guide rail is eliminated, the friction loss is reduced, and the power transmission efficiency is improved. These properties make bushless roller chains more efficient and durable than traditional roller chains. It’s also less noisy. If you are looking for a chain with a lower noise level, a bushingless roller chain may be the right choice for you.

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.
chain

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.
