Abstract

Sealed roller bearing with a plastic jacket, in which this jacket, continuing in the radial direction on at least one side of the roller bearing, is designed to form a seal by way of at least one ring lip with a shaft or the like, characterized in that the seal has annular grooves extending axially on both sides of the radial side surfaces, and in that at least one edge area in the transition from the bore surface to the radial side surfaces is designed as a tilting edge, which lifts the ring lip radially from the sealing surface during axial displacement.
