A sliding material for gliding elements includes a thermoplastic matrix material and a PTFE additive. The PTFE additive includes at least two different types of PTFE having different molecular weights.

A rolling bearing, in particular a ball bearing, is in the form of two bearing rings that are mounted so as to be rotatable relative to each other about an axis. The roller bearing includes an inner ring and an outer ring which each form a guide portion of a guide. The guide portion surrounds the axis with the portion formed by the inner ring is radially opposite the portion formed by the outer ring. In the guide, rolling bodies are distributed around the axis and rest on the two guide portions. When the bearing rings rotate, the rolling bodies roll on the two guide portions. At least one of the rings has a slide ring as the guide portion and a stabilising ring on the slide ring. The slide ring and the stabilising ring are produced from first and second plastics materials, respectively. The first plastics material is softer than the second plastics material.
