Why are angular contact bearings usually used in pairs?

1. Reduction of radial and axial loads

Angular contact bearings used in pairs can be subjected to radial and axial loads both horizontally and vertically, thus reducing the effect of loads on individual bearings. This improves bearing life and reliability.

2. Improvement of assembly accuracy

If the angular contact bearing is used alone, its assembly error will have a great impact on the performance of the bearing. However, when used in pairs, the assembly error can be eliminated to a certain extent by adjusting the clearance between two angular contact bearings.

3. Improvement of rotational accuracy

Angular contact bearings used in pairs can eliminate the internal geometric errors of the bearings, thus improving rotational accuracy and reliability. This is very important for high-speed operation and mechanical equipment requiring high precision.
