Thermally insulated anti-friction bearing

摘要

An anti-friction bearing, which has an outer ring, an inner ring and rolling bodies that are arranged between the rings, distributed over a circumference of the rings, and roll on the rings. For an increase of thermal insulation, electrical insulation and the like, a film section, which is manufactured without the removal of material from a plastic film, is attached on an outer circumference of the outer ring over at least part of an axial width of the outer ring and at least over part of an outer circumference of the outer ring.
