Angular contact ball bearings can bear radial load and axial load simultaneously. It can work at a high speed. The greater the contact angle, the higher the axial bearing capacity. The contact angle is the angle between the contact point of the ball and raceway in the radial plane and the vertical line of the bearing axis. High precision and high speed bearings usually take 15 degrees of contact angle. Under the action of the axial force, the contact angle will increase.
 
The inner and outer rings of the angular contact ball bearings have raceways, and the inner and outer rings can move relative along the axial direction of the bearing. This type of bearing is especially suitable for loading compound loads, that is, radial and axial loads simultaneously. The axial load bearing capacity of angular contact ball bearings increases with the increase of contact angle A. The contact angle is the angle between the contact point of the ball and raceway in the radial plane and the vertical line of the bearing axis.
 
The models of angular contact ball bearings are divided into: alpha =15 angle contact ball bearing (70000C type); alpha =25 angle contact ball bearing (70000AC type); alpha =40 degree angle contact ball bearing (70000B type); [70000C (AC, B) /DB type of double angle contact ball bearing with back to back pair; face to face double angle contact ball bearing [70000C (AC and B) type]; series pairs Double angle contact ball bearing [70000C (AC, B) /DT]; double row angular contact ball bearing (type 00000) with ball gap; double row angular contact ball bearing (00000A) without ball gap; double row angular contact ball bearing (00000A-Z) with dustproof cover without ball gap; double row angular contact ball bearing with dust-proof cover with two sides. 00000A-2Z type); a double row angular contact ball bearing (00000ARS) with a seal ring without a ball gap; a double row angular contact ball bearing (type 00000A-2RS) without a ball gap, two sides with a seal, and a four point angle contact ball bearing (QJ0000 type), with 13 kinds.
 
Single row angular contact ball bearings can only bear axial load in one direction, which will cause additional axial force when bearing radial load. It can only restrict the axial displacement of the shaft or shell in one direction. The contact angle of angular contact ball bearing is 40 degrees, so it can bear great axial load. Angular contact ball bearings are non separable designs, with different shoulders 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 machined lower, so that more steel balls can be loaded into the bearing.
 
Double row angular contact ball bearings can withstand larger radial load combined radial and axial loads and torque loads, limiting the axial displacement of the shaft in two directions. The obliquity between the inner and outer rings of the double row angle contact ball bearing, which is mainly used to limit the axial and axial displacement of the shaft and the shell, is limited by the inner and outer rings. The allowable inclination angle depends on the internal clearance of the bearing, the size of the bearing, the internal design and the force and torque acting on the bearing, and the maximum allowable inclination angle should ensure that the bearing will not be produced in the bearing. High additional stress. If the inclination angle exists between the bearing and the outer ring, the life of the bearing will be affected, and the running accuracy of the bearing will be reduced and the running noise will increase. Double row angular contact ball bearings usually adopt nylon cage or brass solid cage. Attention should be paid to the installation of double row angular contact ball bearings, although the bearings can bear a two-way axial load, but if there is a gap on one side, the main axial load should not be allowed to pass through the notched side of the edge. When bearing is used, the side raceway without the ball gap should be noted to bear the main load.
