Abstract

Spring strut bearing, which has an antifriction bearing that is arranged axially between an upper carrier part and a lower carrier part and a sealing ring. The upper carrier part has two upper rims, and the lower carrier part has two lower rims. The upper rims and the lower rims engage into one another with the result that a combined labyrinth and slip-ring seal is formed.
