Materials Used in Bearings

Metallic materials used in bearings Chrome steel SAE 52100. Roller, ball and tapered roller bearings are usually made of chrome SAE 52100 bearing steel. This material has excellent wear resistant capacity and a Rockwell hardness of about 64 HRC. Bearings made of chrome steel can function at temperatures up to 120 ° C, and upon heat treatment, they can even go as high as 220 ° C.
