There are raceways on both the inner and outer rings of angular contact ball bearings, and the inner and outer rings can move relative to each other along the axial direction of the bearing. This type of bearing is particularly suitable for bearing composite loads, i.e. loads acting both radially and axially. The axial load bearing capacity of angular contact ball bearings varies with the contact angle α Increase with the increase of. The contact angle is the angle between the line connecting 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: α= 15 ° angle contact ball bearing (70000C type); α= 25 ° angle contact ball bearing (70000AC type); α= 40 ° angle contact ball bearing (70000B type); Back-to-back paired double angular contact ball bearings [70000C (AC, B)/DB type]; Face to face paired double angular contact ball bearings [70000C (AC, B)/DF type]; Series paired double angular contact ball bearings [70000C (AC, B)/DT type]; Double row angular contact ball bearings with ball mounting notches (00000 type); Double row angular contact ball bearings without ball gaps (00000 A type); Double row angular contact ball bearing (00000 A-Z type) with no ball gap and a dust cover on one side; Double row angular contact ball bearings (00000 A-2Z type) without ball gaps and with dust covers on both sides; Double row angular contact ball bearing (00000 ARS type) with sealing ring on one side and no installation gap; Double row angular contact ball bearings (00000 A-2RS type) with sealing rings on both sides and no ball gap; There are 13 types of four point angular contact ball bearings (QJ0000 type).

Single row angular contact ball bearings can only withstand axial loads in one direction, which will cause additional axial forces when subjected to radial loads. And can only limit the axial displacement of the shaft or shell in one direction. The contact angle of angular contact ball bearings is 40 degrees, so they can withstand significant axial loads. Angular contact ball bearings are non separable designs, with varying shoulder heights on both sides of the inner and outer rings. In order to improve the load capacity of the bearing, one side of the shoulder will be machined lower, allowing the bearing to accommodate more steel balls.

Double row angular contact ball bearings can withstand large radial and axial combined loads and torque loads, limiting the axial displacement of both sides of the shaft. The tilting ability between the inner and outer rings of the double row angular contact ball bearing, which is mainly used to limit the bidirectional axial displacement of the shaft and shell, is limited. The allowable tilting angle depends on the internal clearance of the bearing, bearing size, internal design, and the forces and moments acting on the bearing. The maximum allowable tilting angle should ensure that there is no excessive additional stress generated in the bearing. If there is a tilt angle between the inner and outer rings of the bearing, it will affect the service life of the bearing, and at the same time cause a decrease in the operating accuracy of the bearing and an increase in operating noise. Double row angular contact ball bearings generally use nylon cages or brass solid cages. When installing double row angular contact ball bearings, attention should be paid. Although the bearing can withstand bidirectional axial loads, if there is a ball gap on one side, attention should be paid not to let the main axial load pass through the groove edge on the side with the gap. When using bearings, attention should be paid to ensuring that the raceway on the side without the ball groove bears the main load.

Paired installation of angular contact ball bearings can withstand radial and axial combined loads mainly based on radial loads, as well as pure radial loads. The series configuration can only withstand axial loads in a single direction, while the other two configurations can withstand axial loads in either direction. This type of bearing is usually selected by the manufacturer to be paired and submitted to the user. After installation, there is a pre press interference, and the ring and steel ball are in an axial pre load state, thereby improving the stiffness and rotational accuracy of the entire set of bearings as a single support.
