Abstract
A method for producing a rolling bearing component, in which, before ustenizing, the steel is subjected to cold deformation and quenching is such that the bainitic structure is obtained; and a rolling bearing component produced by the method, such as a rolling bearing ring from 1C to 1,5Cr type series steel, in which at least the surface of the rolling bearing component has a bainitic structure and the service life of the bainitic structure is considerably increased over a component not subjected to cold rolling.
