ABSTRACT:
In a roller chain, a plastic bushing sleeve has flanges which are integrally formed on the ends of the sleeve by injection molding. These flanges fit into complementary recesses in the outer faces of the inner link plates of the chain and prevent axial translation of the sleeve. The flanges and recesses may be made non-circular to prevent rotation of the sleeve. Alternatively, complementary projections and depressions can be formed on circular flanges and on the floors of the recesses. A similar sleeve is incorporated into the rollers of the chain.
