Angular contact ball bearing is divided into many kinds of structures, single row angular contact ball bearings can sustain radial load and axial load in single direction. DB combination, DF combined into a four point contact, double row angular contact ball bearings can sustain radial and bi-directional axial load. Angular contact ball bearings are suitable for high speed and high precision rotation. This type of bearing is mainly used in machine tool spindle, high frequency motor, oil pump, air compressor, such as printing machine. Four point contact ball bearing used for rolling mill oil roller box to bear axial load.
