Abstract:
A furniture swivel of the thrust bearing type is taught herein having a top plate and bottom plate made entirely of an internally-lubricated polymer. A central top hole surface projects upwardly and integrally from the top plate, and a central top annular surface projects upwardly and integrally from the same plate wherein two flat, raised annular surfaces are integrally defined on the top inside surface of the top plate made of the polymer. The bottom plate is substantially similar to the top plate made entirely of the polymer and has a raised central bottom hole surface in face-to-face relation with the central top hole surface and a raised bottom annular surface in face-to-face relation with the top annular surface, wherein load support and low-friction rotation is maintained without overlain metal components.
