Abstract

A component of a rolling-element bearing, such as a bearing inner ring having an inner ring flange, a bearing outer ring having an outer ring flange or a rolling element having an end surface, includes a solid slide layer having a lower coefficient of friction than a material to which the slide layer is attached which slide layer reduces frictional contact between the component and another component against which the slide layer slides during bearing operation.

Description

technical field [0001] The invention relates to a device for a rolling bearing and a method for producing a device for a rolling bearing. Background technique [0002] In rolling bearings (for example cylindrical roller bearings (CRB), tapered roller bearings (TRB)) axial stresses can develop such that the rolling bearings press against the inside of the rib (guide rib). Therefore, sometimes there may be a relatively high axial pressing force acting on the inner side of the rib and the end surface of the rolling element. In addition, sliding friction contact or sliding friction may sometimes occur between the rolling elements and the rib. Sometimes a sliding frictional contact between two parts, for example two parts made of steel, can lead to higher wear of the parts and / or higher friction between the parts. [0003] Higher friction in this area, for example between the end faces of the rolling elements and the guide rib, can also lead, for example, to higher energy consu...
