PROBLEM TO BE SOLVED: To provide a rubbing seal which contacts with a lower force as the rotational speed increases. SOLUTION: This invention relates to a roller bearing 1 which is sealed by a sealing washer 6 which forms the 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 center 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.
