ROLLER WITH SELF-LUBRICATED BEARING

摘要

A roller with a self-lubricating bearing or bearing (10) is formed by molding a laminated bearing insert (12) in-situ within a nylon support or member (14). The bearing (10) provides a one-piece, self-lubricating device to replace conventional multiple-piece bearing assemblies which typically include a nylon member having an integral metallic sleeve rotatably engaged with a conventional needle or journal bearing. An embodiment of the present invention includes a roller (10') fabricated by press-fitting the laminated bearing insert (12) into a member (14') fabricated from a metallic material. The rollers (10) and (10') of the present invention have several advantages over the prior art, including improved concentricity between the load bearing layer and roller, closer tolerances and elimination of parts and assembly steps.
