NSK angular contact ball bearing is a kind of bearing which can work at high speed. The greater the contact angle, the higher the axial bearing capacity. High precision and high speed bearings usually take 15 degree contact angles. Under the action of the axial force, the contact angle will increase.
The single row NSK angular contact ball bearings can only bear one axial load, which will cause additional axial force when bearing radial load. It can only restrict the axial displacement of the shaft or shell in one direction. The contact angle of the NSK angular contact ball bearing is 40 degrees, so it can bear a large axial load. NSK angular contact ball bearings are non separable designs, with different shoulders on both sides of the inner and outer rings. For the high bearing load capacity, the shoulder of one side will be machined lower, so that more steel balls can be loaded into the bearing.
If twin pairs are installed, the outer ring of a pair of bearings is opposite, that is, the wide end faces the wide ends, and the narrow ends face the narrow ends. This avoids the additional axial force and can cause the shaft or shell to be confined in the axial clearance range in two directions.
NSK angle contact ball bearing can have relative displacement on the horizontal axis because of its inner and outer raceway, so it can bear radial load and axial load at the same time - joint load (single row NSK angle contact ball bearing can only bear a single direction axial load, so it is usually used in pairs).
The material of the cage is brass, synthetic resin and so on, which are distinguished according to the bearing form and the use conditions.
NSK angular contact ball bearings are mostly manufactured by foreign bearing manufacturers. Many domestic applications are used in imported equipment, such as NSK angular contact ball bearings 3204RS, etc.

The main use of NSK angle contact ball bearings:
Single row NSK angular contact ball bearings: machine spindle, high frequency motor, gas turbine, centrifuge, small car front wheel and differential pinion shaft.
Double row NSK angular contact ball bearings: oil pumps, roots blowers, air compressors, all kinds of transmission, fuel injection pumps, printing machinery.
