A method for producing a bearing component includes providing a bearing component blank with an iron-based metal substrate, hardening the metal substrate, treating the metal substrate by an alkaline treatment bath in a region to form an iron oxide-based blackening layer as a conversion layer with an initial layer thickness (db) on the region, and rolling a spherical body over the region to compress the conversion layer in the region to form a bearing component with a protective layer having a final layer thickness (de) that is less than 95% of the initial layer thickness (db). The spherical body may be a component part of a hydrostatic finish rolling tool or a hydrostatic deep rolling tool. The spherical body may include a hard metal or a ceramic.

Method for producing a bearing component, and bearing component

Rolling bearings and methods of making the same are disclosed. The rolling bearing may include an inner ring, an outer ring and rolling elements arranged radially or axially between the inner ring and the outer ring. A coating may be formed at least partially on the inner ring, and/or on the outer ring, and/or on the rolling elements, wherein the coating is formed predominantly from tungsten and is configured to prevent white etching cracks. The rolling bearing may be used in a wind turbine.
