SF - PK three-layer composite bearing, sliding bearing is a novel, it is composed of steel, copper powder layer, PEEK + filling material composition, main performance is reflected in the surface of PEEK materials, belong to high polymer material, heat resistance, abrasion resistance, corrosion resistance. Especially in water-lubricated and less lubricated occasions, the performance is more excellent. Because the surface of PEEK wear-resisting layer more than 0.1 mm thickness, so than the general material SF - 1 significantly prolong service life, is currently in the shock absorber of high quality parts, tanks, rocket lifting parts and machine tool slide guide are used, is a kind of high performance products.
