Abstract
A snap-on wear pad is adapted to be used on conveyor chains. The wear pad includes a resilient, generally cylindrical body portion of a length adapted to fit between the opposite inner side bars of a conveyor chain. The body portion has an axial through hole and an axial entrance slot communicating with the through hole from the outer surface of the body, whereby the body can be snapped onto and resiliently held around the chain roller, bushing, or pin. The wear surface comprises an integral tab portion on the surface of the body opposite the entrance slot, providing an abrasive-resistant sliding surface and means to prevent rotation of the wear pad about the chain roller, bushing, or pin. An alternate construction comprises a composite two-piece wear pad assembly in which identical wear pad halves are similarly snapped onto the chain roller, bushing, or pin from opposite sides to provide a wear surface for both sides of the chain.
