Image Number 2 for United States Patent #5562558.

A chain for use in transmission and transportation with low friction, less wear, and low noises. The chain has central portions directly in engagement with a sprocket tooth face. Each of a number of pins is supported by rolling bearings attached individually to one of inside link plates and outside link plates, and plain bearings attached to the other link plates. With this arrangement, the sprocket tooth face and pin tooth face are brought into rolling contact with one another, and the link plates bend relatively to one another as the pins rotate in rolling contact. Also, the size and weight of the chain are reduced. Since the entire amount of friction and wear are small, power loss and elongation are reduced to thereby preserve a high accuracy of the chain.
