Angular contact ball bearing
Angular contact ball bearings can bear radial loads and axial loads simultaneously. Able to work at a higher speed. The greater the contact angle is, the higher axial bearing capacity is. High precision and high speed bearings usually take 15 degrees of contact angle. The contact angle will increase when the axial force is applied.
Single row angular contact ball bearings can only bear axial load in one direction, and will cause additional axial force when subjected to radial load. And only the axial displacement of the shaft or shell in one direction can be limited. Angular contact ball bearings have a contact angle of 40 degrees and can therefore withstand large axial loads. Angular contact ball bearings are non separable designs with varying degrees of shoulder on both sides of the inner and outer rings. In order to improve the load capacity of the bearing, the shoulder of one side will be processed lower, so that the bearings can be loaded into more steel ball.
Double row angular contact ball bearings can withstand larger radial load, radial and axial joint load and torque load, and limit the axial displacement of the two axis. Mainly used for double row limit shaft and housing bidirectional axial displacement components of angular contact ball bearing inner ring and the outer ring between the tilt of limited internal space, allow the tilt angle depends on the bearing bearing size, interior design and effect on bearing force and moment, and the maximum allowable inclination angle should ensure that the bearing can not generate additional too much stress. If there is an inclination angle between the inner and outer rings of the bearing, the service life of the bearing will be affected, and the running accuracy of the bearing will be reduced and the running noise will be increased. Double row angular contact ball bearings are generally made of nylon cages or brass solid holders. Double row angular contact ballbearing installation should pay attention to, while the bearing two-way axial load, but if a side mounted ball gap, should pay attention not to let the main axial load by Mizobe side gap. In the use of bearings, attention should be paid to make the ball side of the ball without a gap to bear the main load.
