The invention relates to a roller bearing ( 1 ) which is sealed by a sealing washer ( 6 ) which forms a rubbing seal and two gap seals. As a result of positions which are spaced apart from one another in the axial direction of a pivot point (A) and a centre of mass (S) of an elastic support part ( 14 ) that bears the rubbing seal ( 15 ), 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 15 is in contact with a lower force as the rotational speed increases.
