The angular contact ball bearing angle is the angle of the bearing and the angle of the vertical line:
Commonly used 15 degrees is high precision, high speed, and mainly withstand
the angular contact ball bearings of radial force and small partial axial force.
The radial force of the 25 degree and 30 degree angle is relatively large, the axial force of the 40-degree angle is mostly axial force, suitable for the axial load and vertical mounting, and the smaller
the angular contact ball bearing angle, the bearing tolerant The larger the radial force, the smaller the axial force.
