摘要:
A process for producing a plurality of bearing members each of which has a bore defined by an inner bearing surface of self-lubricating material containing lubrication grooves that open into the bore. To perform the process a mandrel is provided having an axial length, spaced apart ends and an outer surface, and one or more rod members is affixed on the outer surface. A parting agent is applied to the mandrel outer surface and rod members and a layer of self-lubricating material is layered over the outer surface and rod members. A filament wound overlayment is applied on top of the layer of self-lubricating material along with a hardenable resin to bond the layer of self-lubricating material and overlayment together. The resin is hardened to form a rigid elongated tube member and the mandrel and rods are removed to expose the inner bearing surface and lubrication grooves. The rigid tube is then severed transversely into a plurality of individual bearing members.
