Single row angular contact ball bearing can only bear the axial load in one direction, which will cause additional axial force when it is subjected to radial load. And can only limit the shaft or shell in a direction of the axial displacement. Contact angle of angular contact ball bearing is 40 degrees, so it can take a lot of axial load. Angular contact ball bearing is a non - separation type of design, the internal and external sides of the shoulder height. In order to improve the load capacity of the bearing, the side of the shoulder is the lower, so that the bearing can be loaded into more steel balls.

 

Double row angular contact ball bearings can withstand larger radial load and axial joint load and torque load, limit the axial displacement of the two aspects. Mainly used to limit the axial displacement of the shaft and shell parts of the double row angular contact ball bearing, the outer ring of the tilt between the limited, allowing tilt angle depends on the internal clearance of the bearing, bearing size, internal design and role in bearing the force and torque, and the maximum allowable angle should ensure that the bearing will not produce high additional stress. If the bearing inner and outer ring between the inclined angle, will affect the bearing life, but also caused the bearing running accuracy, operating noise increases. Double row angular contact ball bearings generally used in nylon holder or brass solid cage. Double row angular contact ball bearing installation should pay attention to, while the bearing two-way axial load. But if a side ball filling gap, pay attention not to let the main axial load through a gap in the side of the ditch. In the use of bearings should pay attention to the side of the ball with the ball to the gap of the main load bearing.

 

Angular contact ball bearings are: type 7000C (=15 / deg), type 7000AC (=25 / deg) and 7000B (=40 / deg) several types.

 

Angular contact ball bearing accuracy rating includes dimensional tolerances and rotation accuracy. The accuracy is expressed as P0 (ordinary), P6 (P6X), P4, P2, P5. In addition, the European and American brands are also using P3, P9,, P7 level, P3 is equivalent to ISO and P6 standards of JIS, P7 is equivalent to P4, P9 is equivalent to P2.
