NSK Angular contact ball bearing

Single row NSK angular contact ball bearing can only bear axial load in one direction, which will cause additional axial force when bearing radial load. And can only limit the axial displacement of the shaft or housing in one direction. NSK angular contact ball bearing has a contact angle of 40 degrees, so it can bear a large axial load. NSK angular contact ball bearing is a non separable design, and the shoulders on both sides of the inner and outer rings are different. In order to improve the load capacity of the bearing, the shoulder on one side will be machined lower, so that the bearing can be loaded with more steel balls

paired double ball bearings
if installed in pairs, make the outer rings of a pair of bearings opposite, that is, the wide end face to the wide end face, and the narrow end face to the narrow end face. In this way, additional axial force can be avoided, and the shaft or housing can be limited to the axial clearance in both directions

because the raceways of the inner and outer rings of NSK angular contact ball bearings can have relative displacement on the horizontal axis, they can bear both radial load and axial load - combined load (single row NSK angular contact ball bearings can only bear axial load in one direction, so they are usually installed in pairs)

the cage is made of brass, synthetic resin, etc., which can be distinguished according to the bearing form and service conditions
NSK angular contact ball bearings are mostly manufactured by foreign bearing manufacturers, and are mostly used in imported equipment in China, such as NSK angular contact ball bearings 3204rs, etc
