Single row angular contact ball bearings

Angular contact ball bearing with contact angle is applicable to high speed and high precision rotary,which can bear combined load.

Standard contact angle is 150,250 and 400 respectively configuring in post position with code"C","AC" and "B".
The more contact angle is,the larger axial load bearing capacity is,the smaller contact surface is,the much more convenient high speed rotary is.
Pretension is made on angular contact ball bearing to increase rigidity and accuracy of bearing.
This bearing creates axial thrust load when being forced by radial load,thus it is configured(or combined)face to face or back to back.
