The basic requirements for the performance of chain materials are generally high strength and good wear resistance, and conveyor chains are no exception. However, compared with the transmission chain, the conveyor chain has a slower speed and a larger load capacity, and the total length of the chain used and the number of chain links are large, so the quality of the chain is large. Especially for large roller conveyor chains, because the quality of large rollers occupies a larger proportion in the chain, the problem of large quality is even more prominent. A chain with too much mass will greatly increase the tension on the chain, thus increasing the consumption of ineffective power. Therefore, reducing the quality of the conveyor chain itself is an important issue in the design of the conveyor chain.
And it has the advantages of reducing friction, noise and not requiring grease lubrication. At present, the strength of engineering plastics is still low, so it can only be used to make small conveyor chains and rollers on lighter conveyor chain attachments. Using oil-containing powder metallurgy materials to make chain sleeves and rollers can also have the effect of reducing friction and not requiring lubrication, and the weight of powder metallurgy materials is lighter than steel, so it has also been greatly developed. Of course, a chain with good performance under high temperature and corrosive conditions is also guaranteed by the use of materials with special properties.

The chain is evolved from the early malleable cast iron chain, S type is ∞-shaped chain plate, and C type is straight chain plate. It is suitable for the occasion where the chain plate slides on the track during the transportation of crops and goods, and the embossed boss (the boss should be higher than the pin rivet head) in the middle of the C-shaped chain plate is suitable for running in the horizontal plane of the chain. The boss is a sliding pair that touches the track to avoid abrasion at the end of the pin and prevent the chain from falling apart.
