Steel ( DIN-St12|ASTM-A366/A366M-97|JIS-SPCC ) +
Aluminum( DIN-AlSn20Cu|SAE-783|JIS-AJL )

Bimetallic bearings(AlSn20Cu), made of low carbon steel as base material, are produced by the process of being rolled mock silver bronze AlSn20Cu strip as layer. They are in conformity with the European RoHS environmental protection standards and widely used in the applications of main shaft and connecting rod of internal combustion engine due to the advantages of lead free, good fatigue resistance, good bump resistance and good load capacity.
