Abstract
A rolling bearing, for example a spherical rolling bearing, such as for media lubrication, includes multiple bearing rings, rolling bodies which roll between the bearing rings, and a coated cage which guides the rolling bodies. The coating of the cage is produced in multiple layers and includes an NiP layer as a first layer. The NiP layer covers a cage main part which is made of a nonferrous metal, and a TiN layer as a cover layer.
Claims10
A rolling bearing comprising:
- bearing rings;
- rolling elements (4) which roll between the bearing rings;
- and
