Angular contact ball bearing have raceways in the inner and outer rings that are displaced with respect to each other in the direction of the bearing axis. This means that they are designed to accommodate combined loads, i.e. simultaneously acting radial and axial loads.The axial load carrying capacity of angular contact ball bearingincreases with increasing contact angle. The contact angle is a defined as the angle between the line joining the points of contact of the ball and the raceways in the radial plane, along which the load is transmitted from one raceway to another, and a line perpendicular to the bearing axis. angular contact ball bearing are produced in a wide variety of designs and sizes.

The characteristics of the angular contact bearing is that it can bear both radial and single direction axial load. The larger contact Angle is, the greater axial load is, the smaller contact Angle is, the smaller axial load is. On the contrary, the smaller contact Angle is, the greater the ability of bearing radial load is, therefore , they are more suitable for high speed applications. According to the different working conditions, it has a variety of equipping ways to withstand different radial and axial load, meet the requirements of high rotational speed and the stiffness of radial and axial direction .

Therefore , it is widely used in precise machine tool spindle.
