Self-lubricated bearings for aerospace applications incorporate dry-film lubricant liners—typically PTFE, MoS₂, or woven PTFE-fibre composites—bonded or press-fitted into metallic races to eliminate the need for external lubrication, and are commonly manufactured to AS81820, ABMA, or MIL-B standards for use in control surface linkages, landing gear articulation points, and flight-critical hinge assemblies.
