Product Description

Open/Closed Angular Contact Ball Bearing 7211B 7311C 7311A 7311B 7012C 7012A 7212C 7212A 7212B 7312C 7312A 7312B for Motors and Generators

The characteristic of angular contact bearing is that it can bear both radial load and single axial load. The larger the contact Angle, the larger the axial load, the smaller the contact Angle, the smaller the axial load. Conversely, the smaller the contact Angle, the greater the ability to bear radial loads, and the more suitable for high-speed applications. According to different working conditions, it can be combined in a variety of ways to obtain different radial and axial load capacity, and meet the requirements of high speed and diameter, and high axial stiffness.
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
