Angular contact ball Bearing

Angular contact ball bearings can bear radial load and axial load at the same time. Can work at higher speeds. The larger the contact angle, the higher the axial load carrying capacity. The contact angle is the angle between the line connecting the contact points of the ball and the raceway in the radial plane and a line perpendicular to the bearing axis. High-precision and high-speed bearings usually take a contact angle of 15 degrees. Under the action of axial force, the contact angle will increase.

There are raceways on the inner and outer rings of angular contact ball bearings, and the inner and outer rings can make relative displacement along the bearing axis. This type of bearing is especially suitable for carrying combined loads, that is, loads acting radially and axially at the same time. The axial load bearing capacity of angular contact ball bearings increases with the increase of the contact angle α. The contact angle is the angle between the line connecting the contact points of the ball and the raceway in the radial plane and a line perpendicular to the bearing axis.

The models of angular contact ball bearings are divided into: α=15° angular contact ball bearings (70000C type); α=25° angular contact ball bearings (70000AC type); α=40° angular contact ball bearings Angular contact ball bearings (type 70000B); 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] ;Double row angular contact ball bearings in series [70000C (AC, B)/DT type]; Double row angular contact ball bearings with filling gaps (00000 type); Double row angular contact ball bearings without filling gaps ( Type 00000A); double row angular contact ball bearings without filling notches, with dust covers on one side (type 00000A-Z); double row angular contact ball bearings without filling notches, with dust covers on both sides (00000A-2Z type); no filling gap, double row angular contact ball bearing with sealing ring on one side (type 00000ARS); double row angular contact ball bearing without filling gap, double row angular contact ball bearing with sealing ring on both sides (type 00000A-2RS); four points There are 13 kinds of angular contact ball bearings (QJ0000 type).
