Engineering chains are engineered for specific purposes and are found in some of the world’s most rugged applications! The chain is strong and durable enough to withstand a variety of stresses. Its high load capacity makes it ideal for challenging jobs. Some of its applications include lumber applications, forklift trucks, and oil drilling. WLY, one of the professional engineering class chains supplier in China, offers China engineering chains at resonable prices. Contact us now if you are interested!
Engineering chains are a special line of chains built for heavy duty applications that require extra strength. The engineering class chains can withstand some of the harshest conditions with superior fatigue and wear resistance. Many styles of engineered chains are available in a variety of material options, such as carbon steel, stainless steel, and cast iron. Contact us for a quote!
Features & Advantages of Engineering Chains
- Overfill fit construction specifically designed to extend chain fatigue life and wear life.
- State-of-the-art heat treatment of chain components ensures longer chain life.
- Pins, bushings and rollers are manufactured to exacting tolerances.
- Selective induction hardened (SIH) pins provide unmatched toughness and wear resistance.
- Backed by extensive engineering and sales support.
Engineer Class Chains for Sale
Engineer class chains can be used in a variety of equipment such as street sweepers and amphibious equipment (swamp trucks), or automatic assembly equipment for conveying applications, or many other conveying processes. Depending on the application requirements, engineering class conveyor chains can have heat-treated or non-heat-treated chain pieces. Pins, sleeves and rollers are heat treated. While the inner link width, chain piece thickness and pin size remain the same, the link pitch and roller size can be varied according to the application requirements without affecting the chain performance.

Types of Engineering Chain
Consists of wear pins, bushings, side rods and a small roller for improved interaction with the sprocket. Applications are typically high speed, with short distances between sprockets. Pitch ranges from 1.654 to 7.50 in. Working loads range from 2,485 to 37,000 lbs.
Rollers are used to convey products and are designed with attachments for attaching load carrying equipment (trays, plates, stands, paddles) to the chain. Pitch ranges from 1.654 to 24 in. Working loads range from 2,100 to 22,300 lbs.
Very similar to transfer chains, except they do not have rollers. Pitch ranges from 2.609 to 7 inches. Working loads range from 2,500 to 25,000 lbs.
There are bushings welded to the side bars and they do not have rollers. They are usually used as transfer chains and sometimes as drive chains. Pitch ranges from 2.609 to 9 inches. Working loads range from 3,500 to 27,600 lbs.
Bar and pin
Don’t have rollers and bushings. Designed for lifting, pulling or dragging products, typically used in high tension applications, tension tables, lifting equipment, dam gates or in-floor conveyors. Pitch ranges from 2.125 to 18 in. Working loads range from 4,000 to 30,000 lbs.
Don’t have rollers and bushings. They are sometimes called drop-forged rivetless chains and are designed for economy and strength, with extra lateral flexibility to bend around corners. A common application is conveyor car systems. Pitch ranges from 3.014 to 9.031 in. Working loads range from 2,000 to 10,800 lbs.
Do not have pins, bushings or rollers. Link rings are cast, forged or molded and joined together to form a chain. Links can be separated and replaced. They lack precision and are often found on older agricultural equipment.
For use where tension is low and corrosion is high. Limited availability. They are typically used for underwater conveyors or chemical applications.
Maintenance of Engineering Chains
Obviously, engineering chains are used in engineering, including some crane chains, cement chains, etc. The environment of engineering chains is not very good, so it is important to maintain and repair them for a long service life.
- The engineering class chains should be suitable for tightness, not too tight, nor too loose. Too tight can increase power consumption, easy to wear the bearings; If the chain is too loose, it is easy to jump and chain off.
- The length should be moderate, not too long, too long or elongated after use, it is difficult to adjust, it can be removed depending on the situation, but it must be an even number.
- If the wear of the industry engineering chain is more serious, then it needs to be replaced by a new chain to prevent it from becoming more and more serious.
- The old engineering chain cannot be mixed with some new chains, otherwise it is easy to produce impact in the transmission and pull off the chain.
- While in work, you should remember to refill the lubricant in time. And the lubricating oil must enter the mating gap of roller and inner sleeve in order to improve the working condition to reduce the wear.
These are some points of maintenance and upkeep of engineering chain, among which lubricant is indispensable and lubricant plays an important role in engineering chain maintenance.
How to Select an Engineering Chain Sprocket
Engineering chain sprockets are used in material handling equipment to transmit power to various components. They are usually used to turn heavy rotating drums, shakeout drums in foundries and pulp mills, and large off-road cranes.
In addition, engineering chains can also be used to drive draglines. This type of chain has an adjustable idler that promotes long chain life. The adjustable idler prevents whipping of the chain. It is especially recommended for drives that have fixed centers.
Aside from the adjustment mechanism, the main function of the idler is to maintain sprocket-wheel contact. To achieve this, the open end of the link should articulate on the pin. Once this is accomplished, the closed end should rotate on the driving tooth.
For optimum operation, the number of teeth on the sprocket should be at least seventeen. When selecting the type of sprocket, consider the type of loading. If th
e application involves high shock loads, an alloy steel sprocket might be a better choice.
Although sprockets can be made of different materials, they all have hardened teeth. If you want to reduce wear on the sprocket, you should consider choosing a sprocket with a larger chain pitch. Small ratios can cause more tooth engagement and a smaller angle of contact. However, they can also decrease chain longevity.
Another good thing to keep in mind is the number of flat plates. Flat plates in each link increase the load capacity of the chain.
