Abstract

A roller bearing which is sealed by a sealing washer that forms a rubbing seal and two gaps. As a result of positions which are spaced apart from one another in the axial direction of a pivot point and a center of mass of an elastic support part that bears the rubbing seal, the latter is loaded with an outwardly acting axial force in the event of an increased rotational speed as a result of the centrifugal force, with the result that the rubbing sealing lip is in contact with a lower force as the rotational speed increases.
