Material

Steel ( DIN-42CrMo4|ASTM-4140|JIS-SCM440 )

Introduction
Hardened steel bearings(42CrMo4), made of medium carbon alloy steel 42CrMo4 as base material, are produced by the process of special heat treatment and finishing. 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 better wear resistance and better load capacity.
