What are the characteristics of the materials selected by bearing custom manufacturers? Why do so many people and manufacturers choose custom bearings? The editor secretly tells you that the materials and sizes of manufacturers who support bearing customization will match the machine better. Now let Xiaobian and everyone learn about the materials used by custom bearing manufacturers. 1. 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. 2. Wear resistance When the bearing is working, not only rolling friction but also sliding friction occurs between the ring, the rolling element and the cage, so that the bearing parts are constantly worn. 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. Hardness Hardness is one of the important qualities of bearing quality, which has indirect influence 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. Anti-rust performance In order to prevent the bearing parts and finished products from being corroded and rusted during processing, storage and use, it is required that the bearing steel should have good anti-rust performance. V. Machinability During the production process of bearing parts, many cold and hot working procedures are required, and bearing steel should have good machining properties.
