NSK Angular Contact Ball Bearing 7312A

Single row Angular contact ball bearings have the following structure

(1)Separate angular contact ball bearings

This bearing the code name for the S70000, the outer ring raceway side no locking, with inner ring, cage, Gang ball component separation, which can be installed separately. These are mostly less than 10mm diameter miniature bearings, for gyroscope rotor, micro motors on the dynamic balance, noise, vibration, stability of the devices have higher requirements.

(2)Non-separation-type angular contact ball bearings

These bearings are locking ring channel, so can not separate the two sets of circles. Divided into three types according to the contact angle

a.Contact angleα=40°,Apply to bear large axial load

b.Contact angleαα=25°,Are used for precision spindle bearings

c.Contact angleαα=15°,Multi-precision bearings for the larger size.

(3)Pair of angular contact ball bearing configuration

Pair of angular contact ball bearing configuration used to support radial load and axial load of occasions, also can take pure radial load and axial load in either direction. Such bearings from the manufacturer in accordance with certain pre-load requirements, matching pairs combination available to users. When the bearings installed in the machine fastening, the complete elimination of the bearings in the clearance, and to preload ring and the key link in the state of the ball, thus increasing the bearings of the steel.

Single row angular contact ball bearings with radial load mainly radial and axial joint load, but also pure radial load to bear, in addition to tandem configuration, the other two configurations can withstand axial load in either direction. In the radial load, will cause additional axial force. Therefore, pairs normally takes to do any matching of bearing, the bearing installed in pairs according to the combination of the outer ring is divided into different sections: back to back configuration, face to face configuration, series configuration (also known as: O-type configuration, X-type configuration, T-configuration) of three types.
