Bidirectional thrust angular contact ball bearings are designed for bidirectional positioning of spindles. These bearings are combined with cylindrical roller bearings of the NN 30 K or N 10 K series and mounted in the same housing bore. This bearing combination simplifies the machining of the housing bore.
The nominal inner and outer diameters of bidirectional thrust angular contact ball bearings are the same as those of corresponding cylindrical roller bearings. However, the housing ring outer diameter tolerance combined with the recommended housing bore and geometric tolerances for super-precision cylindrical roller bearings allows the housing bore to have an appropriate radial clearance. This clearance is sufficient to prevent the thrust bearing from being subjected to radial loads if the outer ring is not pressed axially in the housing.
