Material
Steel ( DIN-St12|ASTM-A366/A366M-97|JIS-SPCC ) +
Bronze ( DIN-CuSn6.5P0.1 )

Introduction
Bimetallic bearings(CuSn6.5P0.1), made of low carbon steel as base material, are produced by the process of being sintered tin bronze CuSn6.5P0.1 powder as layer. They are in conformity with the European RoHS environmental protection standards and widely used in the applications of automotive, truck, hydraulic transmission and engineering machinery due to the advantages of lead free, good wear resistance and good load capacity.
