JF-800 product description
JF-800 bimetal bearing is a steel-copper alloy product with low carbon steel plate as the base material and sintered CuPb10Sn10 or CuSn6Zn6Pb3 material on the surface. This product is one of the dual alloy bearings with the strongest bearing capacity. It is used for balance axle bushings and gaskets of heavy-duty vehicles; driven wheels of bulldozers; and automobile steel plate bushings. It is a very versatile high-load low-speed plain bearing.
