 Material

Steel ( DIN-St12|ASTM-A366/A366M-97|JIS-SPCC )

Introduction
Hardened steel bearings(St12), made of low carbon steel St12 as base material, are produced by the process of special heat treatment. They are in conformity with the European RoHS environmental protection standards and widely used in the applications of engineering machinery due to the advantages of good wear resistance and good load capacity.
