ABSTRACT:
In a sealed thrust bearing providing a case which is formed of a corrosion resisting material and fixedly fitted to an outer race, an outer seal ring which is fixedly fitted to the outer peripheral edge of an inner race, and an inner seal ring which is fixedly fitted to an inner flange, the outer peripheral edge of a first outer seal lip forming the outer seal ring is slidingly contacted with the inner peripheral surface of the outer cylindrical portion of the case. The end edge of a first inner seal lip forming the inner seal ring is slidingly contacted with the flat portion of the case. In the inner peripheral edge of the flat portion, an inner cylindrical portion is so formed as to cover the sliding contact portion between the end edge of the first inner seal lip. The sealed thrust bearing can prevent the sliding contact portions thereof from being worn greatly even if rain, mud or the like splash on them.
