Product Description

Angular contact bearings can bear radial load and axial load simultaneously. It can work at very high speed. The larger the contact angle, the higher the axial bearing capacity. High precision and high speed bearings usually take 15 degrees contact angles. Under axial force, the contact angle will increase. Contact angles are generally divided into 15, 30, and 40 degrees, expressed by the letters C, A, B respectively. Generally used in high frequency motors and centrifuges.General used for machine tool spindle, high frequency motor, gas turbine, centrifuge, small car front whee.
 
Angular contact ball bearing accuracy class includes dimensional tolerance and rotation accuracy. From low to high accuracy is expressed as P0(ordinary), P6(P6X), P5, P4, P2, in addition, P3, P7, P9 are also used in European and American brands to indicate accuracy levels, P3 is equivalent to level P6 of ISO and JS standards, P7 is equivalent to level P4, and P9 is equivalent to level P2.

Angular contact ball bearings are a variant of deep groove ball bearings and have prominent features.
1.Simple structure;
2.Higher limit speed;
3.Smaller friction torque;
4.Can withstand radial and axial load at the same time;
5.At the same external dimensions, it can withstand larger dynamic and static load capacity than deep groove ball;
6.High rotary precision and low noise.
