These characteristics are the key to bearing durability

Author:


Bearing material performance characteristics is the key to determine the service life of the bearing, then, they have what characteristics?

1.Contact fatigue strength

   Bearing in the role of cyclic load, the contact appearance is easy to fatigue damage, that is, cracking spalling, will greatly affect the service life of the bearing. Therefore, in order to extend the service life of the bearing, bearing steel must have high contact fatigue strength.

2.Wear resistance

Bearing to complete the task, the collar, rolling body and maintain the frame between not only rolling friction, but also will occur sliding friction, so that the bearing parts have been wear and tear. In order to reduce the wear and tear of the bearing parts, maintain the bearing accuracy and stability, prolong the service life, bearing steel should have very good wear resistance.

3.hardness

Hardness is one of the important indexes to evaluate the quality of bearing, contact fatigue strength, wear resistance, elastic limit have indirect influence. Bearing steel in the use of hardness, individual to reach HRC61 ~ 65, higher hardness can make the bearing to achieve higher contact fatigue strength and wear resistance.

4,.anti-rust performance

In order to avoid bearing parts and finished products in the process of processing, sending and use of the process of erosion and rust, bearing steel should have good anti-rust properties.

5.processing performance

Bearing parts in the processing, through many cold, hot processing procedures, in order to meet a small amount, high effectiveness, high quality requirements, bearing steel should have good processing performance. For example, cold, hot molding properties, cutting performance, hardenability.
