As we know, SKF double direction angular contact thrust ball bearings were developed by SKF Corporation to axially locate spindles in both directions. These bearings are intended for mounting in combination with cylindrical roller bearings in the NN 30 K or N 10 K series in the same housing bore. And these bearings combination simplifies machining of the housing bore.
