Single row angular contact ball bearings can only bear axial load
in one direction. When this type of bearing is subjected to pure
radial load, because the line of action of the rolling element load
and the line of action of the radial load are not in the same
radial plane, an internal axial component of force is generated, so
it must be installed in pairs.
Single row angular contact ball bearing structure:
1. Separate angular contact ball bearings
The code name of this kind of bearing is S70000. There is no lock on the outer ring raceway, and it can be separated from the inner ring, cage, and ball assembly, so it can be installed separately. These types of miniature bearings with inner diameters less than 10mm are mostly used in gyroscope rotors, micro motors and other devices that have high requirements for dynamic balance, noise, vibration, and stability.
2. Non-separable angular contact ball bearings
The ring channel of this type of bearing has a lock, so the two rings cannot be separated. There are three types according to the contact angle:
①Contact angle α=40°, suitable for bearing larger axial load;
②Contact angle α=25°, mostly used for precision spindle bearings;
③The contact angle α=15°, which is mostly used for large-sized precision bearings.
