摘要: An assembly includes a composite metal-polymer bushing having an outer metal layer with inner surface, particles sintered to the polymer material between particles, finished interior surface collectively defined by and exposed portions of plurality interstices formed material, ridges that protrude above particles. The occupy at least about 8% area cylindrical reference nominally coinciding surface. also crankshaft journal partially received within supported is polished finish 0.1 microns or less reduce wear rate bushing.
