A rolling element bearing of the type comprising two annular bearing elements between which run a plurality of rolling elements, in which the interior of the bearing is sealed by an annular seal between the two annular bearing elements. The seal comprises an annular resilient element supported on the inside by a reinforcement washer, the outer diameter of which is less than the outer diameter of the resilient washer. The outer rim of the resilient washer is housed in an annular groove on the inner curved surface of the outer annular bearing member, which separates this surface into a first part, on the inside of the groove, and a second part, on the outside of the groove. The diameter of the said second part is greater than that of the said first part but less than that of the reinforcement washer which thus abuts a shoulder formed by the said first part. |
