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.

摘要： A sealing ring comprising a sealing sleeve that is made of a polymeric material and is essentially L-shaped. A fastening region extends essentially in a radial direction and a sealing region extends essentially in an axial direction. The sealing region surrounds, in sealing manner, a surface of a machine element to be sealed by exerting radial tension. The sealing region has, on the side facing the surface, at least one back-feeding device for conveying a medium to be sealed in the direction of the space to be sealed off. The back-feeding device has a profile with a volumetric delivery that decreases from the space to be sealed off in the direction of the surroundings.

摘要： To provide a wheel support bearing assembly in which the frictional resistance can be effectively reduced while effects of minimizing leakage of the filled lubricant and ingress of dust and muddy water from outside of the bearing assembly are secured, the wheel support bearing assembly includes an outer member 1, an inner member 2 positioned inside the outer member 1 with an annular working space defined between it and the outer member 1, and rows of rolling elements 3 accommodated within the annular working space and rollingly received in part within outer raceways 4 in the outer member 1 and in part within inner raceways 5 in the inner member 2. Opposite open ends of the annular working space are sealed by respective sealing members 7 and 8 which are secured to one of the outer and inner members 1 and 2. Each of those sealing members 7 an 8 has a plurality of elastic sealing lips 10a to 10c or 12a to 12c having their free ends oriented towards associated sealing surfaces 2c defined on the other of the outer and inner members 1 and 2, or 15aa and 15ba defined on a sealing contact member 15 secured to the other of the outer and inner members 1 and 2. Of those elastic sealing lips, the axially innermost sealing lips 10a and 12a function as a non-contact sealing lip that defines a respective gap of a size null1 and null2 sufficient to provide a non-contact sealing effect. The remaining sealing lips 10b, 10c, 12b and 12c function as a contact sealing lip.
