Double-direction thrust ball bearing 52 series

brasssteel

The double direction thrust ball bearings have two cages with balls positioned between the central shaft washer and two housing washers with flat seating surfaces. The central shaft washer has raceways for balls on both sides and is mounted on the shaft. The double direction thrust ball bearings can carry axial loads acting in both directions. They cannot carry radial forces. The boundary dimensions of the thrust ball bearings indicated in the dimension tables correspond to the international dimensional plan ISO 104. The designation of the bearings in the basic design is indicated in the dimension tables. The differences from the basic design are designated by additional symbols in accordance with the STN 02 4608. The thrust ball bearings have strip steel cages which are not marked. For special applications, some bearings types are available with a machined brass cage (M). Bearings with these cages are only made to order. Thrust ball bearings are usually produced in normal tolerance class P0 (symbol P0 is not shown). In special cases of arrangement, demanding higher accuracy, bearings are produced in higher tolerance classes P6. Tolerances of accuracy, deviations of dimensions and operation are stated in ISO STN 199.
