Thrust ball bearings with bidirectional angular contact

Bidirectional Angular Contact Ball Thrust Bearings

SKF bidirectional angular contact ball thrust bearings are designed to axially position shaft ends in both directions. These bearings are intended to be mounted together with NN 30 K or N 10 K series cylindrical roller bearings in the same bearing housing. This bearing combination facilitates the machining of the bearing housing.

Bidirectional angular contact ball thrust bearings are produced with the same nominal bore size and outer diameter as the corresponding cylindrical roller bearings. However, the outer diameter tolerance of the bearing washers, along with the recommended geometric tolerances for super precision cylindrical roller bearings under light to normal load and rotating inner ring load, will result in an appropriate radial clearance in the bearing housing (standard conditions for bearing tolerances). This clearance is sufficient to prevent radial loads from acting on the thrust bearing, provided that the outer ring does not axially lock into the housing.
