ANTI-FRICTION BEARING

摘要

The invention relates to an anti-friction bearing, consisting of at least one internal race and at least one external race, a number of anti-friction bodies, in particular balls being provided between said races. The anti-friction bodies are guided in a cage, which consists of plastic, said plastic being at least partially composed of a polyarylene sulphide. To obtain improved material characteristics, the plastic of the cage has the following composition: between 5 and 50 wt. % modified polyolefin; between 40 and 95 wt. % polyarylene sulphide; between 0 and 60 wt. % additional additives and/or processing adjuvants.
