摘要： A seal for a track roller bearing, the bearing including an outer ring an inner ring and a bearing arrangement of rolling bodies or of a sliding body between the bearing rings. A respective thrust washer at each lateral side of the outer ring and extending radially past the bearing arrangement. A circumferential groove around the periphery of the thrust washers. A respective seal between the outer ring and each thrust washer, the seal including a first axially extending leg with a shoulder in the groove in the thrust washer and including a second obliquely radially and axially outwardly extending leg terminating in a sealing lip which is received in a recess in the outer ring. An annular shoulder defines the axial outside of the recess and the inner surface of the shoulder is gap spaced from the lip enabling the oblique arm to deflect outwardly upon over pressure of the bearing.
