What are the five basic properties of spherical roller bearings?
When the bearing (type 35 spherical roller bearing) is working, not only rolling friction but also sliding friction occurs between the rings, rolling elements and cages, causing constant wear of the bearing parts. In order to reduce the wear of bearing parts, maintain bearing accuracy and stability, and extend service life, bearing steel should have good wear resistance.
Five basic properties of spherical roller bearings:
1. Wear resistance:
When the bearing (type 35 spherical roller bearing) is working, not only rolling friction but also sliding friction occurs between the rings, rolling elements and cages, causing constant wear of the bearing parts. In order to reduce the wear of bearing parts, maintain bearing accuracy and stability, and extend service life, bearing steel should have good wear resistance.
2. Contact fatigue strength
Under the action of cyclic loads, the contact surface of the bearing is prone to fatigue damage, that is, cracking and peeling, which is the main damage form of the bearing. Therefore, in order to increase the service life of the bearing, the bearing steel must have high contact fatigue strength.
3. Hardness
Hardness is one of the important qualities of bearings and has a direct impact on contact fatigue strength, wear resistance and elastic limit. The hardness of bearing steel in use conditions generally needs to reach HRC61~65, so that the bearing can obtain high contact fatigue strength and wear resistance.
4. Anti-rust performance
In order to prevent bearing parts and finished products from being corroded and rusted during processing, storage and use, bearing steel is required to have good anti-rust properties.
5. Processing performance
During the production process, bearing parts must go through many cooling and hot processing processes. In order to meet the requirements of large quantities, high efficiency, and high quality, bearing steel should have good processing properties. For example, cold and hot forming properties, cutting performance, hardenability, etc.
