Steel ( DIN-St12|ASTM-A366/A366M-97|JIS-SPCC ) +
Bronze ( DIN-CuPb24Sn|SAE-49)

Bimetallic bearings(CuPb24Sn), made of low carbon steel as base material, are produced by the process of being sintered leaded tin bronze CuPb24Sn4 powder as layer. They are widely used in the applications of main shaft and connecting rod of internal combustion engine due to the advantages of good fatigue resistance, good bump resistance and good load capacity.
