The invention relates to a method for producing a rolling bearing ring featuring an improved robustness against the formation of white etching cracks (WEC), wherein the rolling bearing component, which is made of a hypo-eutectoid heat-treated steel containing C in an amount of 0.4-0.55% and Cr in an amount of 0.5-2.0% in order to form a hardened boundary layer, is inductively heated, then quenched and subsequently tempered.

Method for producing a rolling bearing ring having an improved robustness against the formation of white etching cracks (WEC)

A coated component, in particular to a rolling bearing part, made from a metallic substrate (), and a PVD coating (), which is applied to the substrate (), formed of chromium and having a thickness of less than 2 &#x3bc;m, wherein the PVD coating () forms the surface of the component, and a compound of chromium and at least one further element is formed on the component surface.

Coated component

A method for operating a bearing arrangement () including at least one rolling bearing (). The method provides for applying a positive electric potential to a bearing part () of the rolling bearing (), another part () of the bearing arrangement () being connected as a cathode, and a current flowing between the bearing part () and the cathode () is limited.
