How to Choose Slewing Bearing Grease? - BRS Bearing

2/11/2020· When the slewing bearing is working, it is necessary to use grease to lubrie the bearing, which can reduce the friction coefficient of the bearing and reduce the energy loss during the operation of the bearing, thereby ensuring the mechanical accuracy and also the main method to extend the life of the bearing.

What is the working principle of one way bearings?

13/4/2020· The basic concept of wedge one way bearings requires that the friction coefficient of the wedge is related to the sudden torque generated by the inner ring in the driving direction. This friction value must be greater than the tangent of the self-locking angle. If the conditions are not safe, wedging will not occur.
