Abstract: A self-lubricating connector or roller is formed by molding a laminated bearing insert in-situ within a nylon support or member. The connector 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 alternate embodiment of the present invention includes a connector fabricated by press-fitting the laminated bearing insert into a member fabricated from a metallic material. The connectors or rollers 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.

Abstract: A hollow self-lubricating thrust rivet or fastener is adapted to pivotably fasten first and second members to one another. The fastener is laminated on its outer surface with a self-lubricating or lubricious bearing material such as an organic polymer or plastic material. The bearing material provides the fastener with requisite lubricity to enable the members to rotate about the fastener without requiring application of a discrete lubricant to the interface of the fastener and the members. The fastener thus effectively combines the functions of a conventional fastener and a conventional bearing into a single unitary device. The fastener preferably includes an annular thrust portion laminated with the lubricious bearing material and adapted for placement between the members. The thrust portion effectively eliminates the need for installation of a discrete washer between the members.
