NO 2. Description Of Angular Contact Ball Bearing
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. Angular contact 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.
angular contact ball bearing, is made of Chrome Steel. which have a contact angle so that they can sustain significant axial loads in one direction together with radial loads.
The features of  angular contact bearing is that it can bear both radial load axial load, the axial load capacity depends on how big the contact angle is, the bigger angle, the bigger capacity.
angular contact ball bearing  is mainly applied on high speed, high precision and little axial load occasions, such as airplane engine main shaft, machine tool main shaft and main shafts of other high speed precision machine. It can also be applied on high frequency motor, steam turbine, oil pump, air compressor and printing machine etc. It is one of the bearings most widely used in machinery industry.
