Material

Steel ( DIN-55Si7|ASTM-9255/9260|JIS-sup6/sup7 )

Introduction
Hardened steel bearings(55Si7), made of spring steel 55Si7as 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 good wear resistance and good load capacity.
