Single parts for roller chains

A chain consists of inner and outer links. The inner link consists of two inner plates into which, two bushes are pressed and two rollers, which rotate on the bushes. In the case of bush chains

both rollers are ommitted. Thus the bushes are in direct contact with the sprocket teeth. The outer link consists of two outer plates and two bearing pins. By adding outer links, the inner links are connected to form a chain.
