Single Row Angular Contact Ball Bearings


Angular Contact Ball Bearing Introduction:

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.

Classification of Angular Contact Ball Bearing:

Angular contact ball bearings are: 7000C (=15), 7000AC (=25 =25) and 7000B (=40 =40). The bearing's locking port is on the outer ring, which can not be separated from the inner and outer rings, and can bear radial and axial combined loads and axial loads in one direction. The ability to bear axial load is determined by the contact angle. The greater the contact angle, the higher the ability to bear axial load. The bearing can restrict the axial displacement of the shaft or shell in one direction.
The contact ball bearing can bear both radial and axial loads at the same time, and can also bear the pure axial load. The axial load capacity of the bearing is determined by the contact angle and increases with the increase of the contact angle.


Angular Contact Ball Bearing Precision Degree:


The accuracy grade of angular contact ball bearing includes dimension tolerance and rotation accuracy. The accuracy from low to high is expressed as P0 (normal), P6 (P6X), P5, P4 and P2. In addition, European and American brands also use P3, P7 and P9 to express accuracy level. P3 is equivalent to P6 level of ISO and JIS standard, P7 is equivalent to P4 level, P9 is equivalent to P2 level.
