Abstract: 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.

Abstract: 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.

Abstract: A control device within an actuator includes control logic for a second actuator, the second actuator being connected with the first actuator through a communications interface. By storing the control logic in the second actuator, the construction space for this second actuator is optimized. By integrating the control logic into a control device of the first actuator, the power density of the control device is increased.

Abstract: 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.
