Bimetallic bearings(CuPb10Sn10/graphite), made of low carbon steel as base material, are produced by the process of being sintered tin bronze CuPb10Sn powder as layer and rolled diamond oil pockets on the surface of alloy layer for storing graphite. They are widely used in the applications of automotive, truck, hydraulic transmission and engineering machinery due to the advantages of low friction coefficient, good self-lubricating and good load capacity.
