摘要

A cage for a roller bearing comprises a base body with a plurality of pockets for the reception of the roller elements of the roller bearing. At least a part of the surface of the base body is coated with a layer consisting of or containing fullerene-like carbon nitride (FL-CNx), wherein an inter-layer of chromium (Cr) or aluminum (Al) or molybdenum (Mo) or titanium (Ti) or tungsten (W) or a diamond-like coating (DLC) or a metal-mix diamond-like coating (Me-DLC) is arranged between the surfaces of the base body and the layer consisting of or containing fullerene-like carbon nitride.
