Angular contact ball bearings are also have lots of structures, single row angular direction, While double row angular contact ball bearings in DB or DF combination and four-point contact ball bearings can accommodate radial load and axial load in two directions. Angular contact ball bearings suit high-speed rotation and high-precision rotation. These bearings are mainly used in the fields like machine tool spindles, high frequency motors, oil pumps, air compressors, printing machines, etc. For four-point contact ball bearings are mostly used in the roller-boxes of rolling mills to carry axial load.
