What is the material requirements of angular sliding contact bearing?

Everyone knows that angular angular sliding contact bearing can work at higher speeds and can be used in the production and operation of high-frequency motors, printing machinery and other fine chemical machinery. Because this operating form has certain requirements for the material of angular contact ball bearings, it is necessary to pay attention to the selection.

Angular sliding contact bearing material requirements
​​
1. High contact fatigue strength
Under the action of cyclic load, the contact surface of the bearing is prone to fatigue damage, that is, cracking and spalling, which is an important damage form of the bearing. Therefore, in order to improve the service life of the bearing, the bearing steel must have a high contact fatigue strength. At the same time, it also needs to have sufficient tensile strength and impact capacity.

​​
2. Good wear resistance
When the angular sliding contact bearing is working, not only rolling friction but also sliding friction occurs between the ring, the rolling element and the cage, which causes the bearing parts to wear directly. In order to increase the wear of bearing parts, maintain the accuracy and stability of the bearing, and extend the service life, the bearing steel should have good wear resistance.
​​
3. Strong hardness
Hardness is one of the most important qualities of bearing quality, and it has indirect effects on contact fatigue strength, wear resistance and elastic limit. The hardness of bearing steel under operating conditions should reach HRC61~65, which can enable the bearing to achieve higher contact fatigue strength and wear resistance.

​​
4, with anti-rust properties
In order to prevent angular sliding contact bearing parts and finished products from being eroded and rusted during processing, storage and use, normal bearing steel should have good rust resistance.
​​
5. Good processing performance
In the production process of angular sliding contact bearing parts, many cold and hot working processes are required. In order to meet the requirements of small quantity, high force and high quality, bearing steel should have good processing performance. For example, cold and hot formability, machinability, hardenability, etc.
