SAE 52100 BEARING MATERIAL

MATERIAL The process of manufacturing Bearing Steel does not start at a Bearing Plant but at the steel mill. The SAE-52100 standard Bearing Steel contains varying amount of carbon, iron, chromium, manganese, phosphorus, sulphur, silicon, etc. Each of these elements plays a vital role in making the final steel suitable for Bearings. Chromium and carbon allow deep hardening. Where as the combination of Carbon, Chromium and Iron helps to minimize Bearing failures as they increase the surface resistance to abrasion and wear & tear. A proper combination of all these elements make the final Bearing Steel tough enough to withstand shocks & heavy loads and hard enough to resist fatigue.
