What kind of performance does the roller bearing have?


Spherical roller bearing is a kind of roller bearing, because the advantages and value of roller bearing itself are very high. It is very necessary to choose and use in life. This time, let’s briefly talk about the performance of roller bearings.
Wear resistance
When a spherical roller bearing is working, not only rolling friction occurs between the ring, rolling element and the cage, but also sliding friction occurs, so that the bearing parts are constantly worn. In order to reduce the wear of bearing parts, maintain the stability of bearing accuracy and extend the service life, the bearing steel should have good wear resistance.
Contact fatigue strength
Under the action of cyclic load, the contact surface is prone to fatigue failure, that is, cracking and peeling, which is the main 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.
Hardness is one of the important qualities of bearing quality, and it has a direct impact on contact fatigue strength, wear resistance, and elastic limit. The hardness of the bearing steel in use should generally reach HRC61~65, so that the bearing can obtain higher contact fatigue strength and wear resistance.
Anti-rust performance
In order to prevent bearing parts and finished products from being corroded and rusted during processing, storage and use, the bearing steel is required to have good rust resistance.
Processing performance
In the production process of bearing parts, there are many cold and hot processing procedures. In order to meet the requirements of large quantities, high efficiency and high quality, the bearing steel should have good processing performance. For example, cold and hot forming performance, cutting performance, hardenability, etc.
Roller bearings are one that many mechanical parts choose to use. It is very necessary for the needs in life. In the end, roller bearings have many advantages.
