Description	An angular contact ball bearing uses axially asymmetric races. An axial load passes in a straight line through the bearing, whereas a radial load takes an oblique path that tends to want to separate the races axially. So the angle of contact on the inner race is the same as that on the outer race
Use	Angular contact ball bearings better support " combined loads" (loading in both the radial and axial directions) and the contact angle of the bearing should be matched to the relative proportions of each. The larger the contact angle (typically in the range 10 to 45 degrees), the higher the axial load supported, but the lower the radial load. In high speed applications, such as turbines, jet engines, and dentistry equipment, the centrifugal forces generated by the balls changes the contact angle at the inner and outer race. textile machinery, machine tools, automobiles and many other mechanical industries.
Feature	It can bear both radial load and axial load, the axial load capacity depends on how big the contact angle is, the bigger angle, the bigger capacity. This kind of bearing has both higher accuracy and higher rotational frequency, double and muti-matched angular contact ball bearing has pretty high stiffness and rotation accuracy.
