Thrust Ball Bearings – Single Direction – RKB

Single direction thrust ball bearings are composed of a shaft washer, a housing washer and a cage-ball assembly. Series 511, 512, 513, and 514, with flat housing washers, can support only axial forces in one direction and cannot stand any radial load and misalignment. Series 532 and 533 can take axial forces in one direction, but, having sphered housing washers and matched with seat washers U2 and U3, they can compensate shaft misalignments.
