Abstract:
A bearing component formed from a bearing steel, wherein the component has an outer surface and comprises through-hardened bainite and/or martensite and has a substantially homogeneous chemical composition, at least a part of the bearing component having a compressive residual stress profile comprising −25 to −1000 MPa at the near surface, wherein the near surface is defined as a region 500 microns or less below the outer surface.
