Angular contact ball bearings have greater radial load-carrying capacity than ordinary ball bearings, and at the same time, they can withstand large axial loads. Under normal circumstances, they will not be used alone but will be used in pairs to improve the rigidity of the bearing system.
1. Anti-fatigue performance
Angular contact ball bearings are prone to fatigue damage when exposed to the surface under the action of periodic load, that is, cracks and peeling appear, which is an important damage condition of the bearing. Therefore, in order to prolong the service life of angular contact ball bearings, angular contact ball bearings must have high contact fatigue strength.
2. Wear resistance
When angular contact ball bearings are under production tasks, not only rolling friction but also sliding friction occurs between the rings, rolling elements, and the cage, which causes continuous wear of the bearing parts. In order to reduce the wear of bearing parts, maintain the accuracy and stability of the bearing, and extend the service life, angular contact ball bearings should have good wear resistance.
3. Hardness performance
Hardness is one of the important indicators of the quality of angular contact ball bearings, and has an indirect effect on contact fatigue strength, wear resistance, and elastic limit. The hardness of the bearing steel under operating conditions must reach HRC61~65, which can make the angular contact ball bearing achieve higher contact fatigue strength and wear resistance.
4. Elastic limit
In order to prevent excessive plastic deformation under high contact stress, loss of accuracy of angular contact ball bearings, or surface cracks, angular contact ball bearings should have a high elastic limit.
5. Toughness
Many angular contact ball bearings will suffer a certain impact load during use. Therefore, angular contact ball bearings are required to have good impact toughness and fracture toughness to ensure that the bearings are not damaged due to impact.
6. Anti-rust performance
In order to prevent the angular contact ball bearing parts and finished products from being corroded and rusted during processing, storage, and transportation, angular contact ball bearings should have good rust resistance.
7. Processing performance
Angular contact ball bearing parts have to go through many cold and hot processing procedures during the production process. In order to meet the requirements of high efficiency and high quality, angular contact ball bearings should have good processing performance. For example, cold and hot forming performance, cutting performance, hardenability, etc.
The above is the introduction to the performance requirements of angular contact ball bearings. A good quality angular contact ball bearing has a longer service life and reduces the cost of maintenance.
