Design features:

Single row angular contact ball bearings can only withstand axial load in one direction. When such bearings are subjected to pure radial load, they must be installed and used in pairs because the line of action of the rolling body load and the line of action of the radial load are not in the same radial plane, resulting in an internal axial component.

Structure form:

1. Separation type angular contact ball bearing

This bearing code is S70000, its outer ring roller side has no lock, can be separated from the inner ring, cage, ball assembly, so can be installed separately. This kind of micro bearing with inner diameter less than 10mm is used for gyro rotor, micro motor and other devices that have higher requirements for dynamic balance, noise, vibration and stability.

2. Non-separated angular contact ball bearings

The ring groove of this kind of bearing has a lock, so the two rings can not be separated. It can be divided into three types according to the contact Angle:

① Contact Angle α=40°, suitable for bearing large axial load;

② Contact Angle α=25°, mostly used for precision spindle bearings;

③ Contact Angle α=15°, mostly used for large size precision bearings.
3. Configure angular contact ball bearings in pairs

Angular contact ball bearings configured in pairs are used for bearing both radial load and axial load, and can also bear pure radial load and axial load in any direction. This kind of bearing is provided to the user by the manufacturer according to certain pre-load requirements. When the bearing is installed on the machine, the clearance in the bearing is completely eliminated, and the ring and the ball are in a pre-tightening state, thus improving the steel of the combination bearing.
