Self-lubricating bushing for a joint, which is intended to be mounted on a shaft

Self-lubricating hinge connection bushing for mounting on a shaft for translational and/or rotational guidance, comprising a composite material having a modulus of elasticity of between 500 and 6000 N/mm2 allowing deformation upon application of a load and then a return to an initial state upon load removal, wherein the composite material comprises an epoxy or vinylester or polyester resin incorporating reinforcements of thermoplastic fibers with a thickness of between 0.05 and 0.5 mm and including lubricating fillers between 5 and 50% by volume, said bushing having at least one lip formed directly at a time of manufacture as an overrun edge of a bore of a body of the bushing to act as a leak-tight or protective barrier after mounting on the shaft by creating a tightening effect between an inside diameter of said at least one lip, and an outside diameter of said shaft, wherein the tightening between the inside diameter of the at least one lip and the outside diameter of the shaft is between 0.05 and 4 mm.
