Important quality and load of female rod end bearing

- Sep 10, 2018 -

Under the action of cyclic load, the female rod end bearing is very easy to experience fatigue damage, that is, cracking and spalling, which is an important damage situation of the bearing. Therefore, in order to improve the service life of the bearing, the bearing steel must have a high contact fatigue strength.

When the master end bearing is in the task, not only the rolling friction between the ferrule, the rolling element and the maintenance frame occurs, but also the sliding friction occurs, so that the bearing parts can be worn all the time. In order to increase the wear of the bearing parts, maintain the bearing accuracy and stability, and extend the service life, the bearing steel should have good wear resistance.

The hardness of the female rod end bearing is one of the important qualities of the bearing quality, and has an indirect influence on the contact fatigue strength, wear resistance and elastic limit during the operation. The hardness of the bearing steel in the application condition has to reach HRC61~65, which makes the bearing achieve high contact fatigue strength and wear resistance.

In order to prevent the bearing parts and finished products from being eroded and rusted during processing, storage and operation, the bearing end bearings are required to have good rust prevention performance.
