  • Self-lubricating thrust rivet and its method of manufacture
    Patent number: 6272728
    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.
    Type: Grant
