DB, DF, and DT arrangements respectively. (Fig. 1). DB and DF arrangement sets can take axial loads in either direction. Since the distance of the load centers of DB bearing set is longer than that of DF bearing set, they are widely.

The NSK range of angular contact ball bearings has been designed to meet the increasingly demanding requirements of original equipment manufacturers. These bearings have a contact angle so that they can sustain significant axial loads in one direction together with radial loads. Furthermore, since an axial component
