Angular Contact Ball Bearings can withstand both radial and axial loads simultaneously. Capable of operating at higher speeds. The larger the contact angle, the higher the axial bearing capacity. The contact angle is the angle between the contact point line between the ball and raceway in the radial plane and the vertical line of the bearing axis. High precision and high-speed bearings typically have a contact angle of 15 degrees. Under the action of axial force, the contact angle will increase.

Product Information

Angular contact ball bearings have raceways on both the inner and outer rings, which can move relative to each other along the bearing axis. This type of bearing is particularly suitable for bearing composite loads, namely radial and axial loads. The axial 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 contact point line of the ball and raceway on 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 (70000C type); α= 25 ° angular contact ball bearing (70000AC type); α= 40 ° angle contact ball bearing (70000B type); Back-to-back paired double angle contact ball bearings [7000C (AC, B)/DB type]; Face to face paired double angular contact ball bearings [7000C (AC, B)/DF type]; Series paired double angular contact ball bearings [7000C (AC, B)/DT type]; Double row angular contact ball bearing with ball installation clearance (00000 type); Double row angular contact ball bearing without ball clearance (00000 A type); Double row angular contact ball bearing (00000 A-Z type), without ball clearance, with a dust cover on one side; Double row angular contact ball bearing, without ball clearance, with dust covers on both sides (00000 A-2Z type); Double row angular contact ball bearing (00000 ARS type), without ball clearance, with a sealing ring on one side; Double row angular contact ball bearing with sealing rings on both sides, without ball clearance (00000 A-2RS type); There are 13 types of four point angular contact ball bearings (QJ0000 type).

Product Concept

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 bearing's load capacity, 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 significant 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, 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, it should be noted that although the bearings 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 gap bears the main load.
