Sprocket Chain

Additional Details

A chain for engagement with a double sprocket has alternate pin links and center, or bushing, links. The bushing links comprise a single center bar with two laterally extending bushings tightly received therein. The pin links have side bars parallel to the center bars, and the side bars are connected together by laterally extending pins. The pins of each pin link are rotatable received in the near bushings of each of the adjacent bushing links. Rollers are received on each bushing, on each side of the center bar, to define pockets with the side bars and center bars, on each side of the center bars, to receive the teeth of a double sprocket.
