Can bear radial load and axial load, high speed, the greater the contact angle, the higher the axial load carrying capacity.
Single-row ball bearing can only withstand axial load in one direction, in the radial load, will cause additional axial force. And can only limit axial displacement of the shaft or housing in one direction. If pairs of dual-installed, so that a pair of bearing outer ring relative to the wide end of the wide face, narrow face of the narrow face. This will avoid additional axial forces, and the shaft or housing can be limited in both directions in the axial clearance range. Angular contact ball bearing up to 70 kinds of variable structure.

1, the nominal contact angle of 15 °, 25 °, 40 ° three, the greater the contact angle the higher the axial load carrying capacity. High precision and high-speed bearings usually take 15 ° contact angle, the axial force, the contact angle will increase.
2, generally for the inner or outer ring with a lock mouth, inner and outer ring can not be separated. The outer ring is heated and expanded and assembled with the inner ring, the rolling element and the cage assembly. Ball load than the number of deep groove ball bearings, rated load in the ball bearing the largest, strong rigidity, smooth operation.
3, you can use the inner and outer ring to adjust the radial clearance of mutual displacement. Often used in pairs, and the application of pre-load to improve the bearing rigidity. learn more: http://www.szr-bearing.com/product.asp
