Bearing failure issues and corrective measures through surface engineering …

1/1/2018· Cost of bearing failure is nearly 50% due to associated fatigue failure and overall maintenance cost. The amount of loss can be minimized by better practices and appliion of tribology [25] . Although, surface engineering allows a thick protective layer of other substance over bearing surface to resist failure and provides prolonged operation.

Reason analysis and solutions for the problems of slewing bearing …

5/7/2021· Reason analysis and solutions. Check the production date of the slewing bearing, if it has not been used for a long time and the temperature is low, it may be that the grease in the raceway becomes more viscous, causing inflexible rotation. At this time, you can try to run it for a few laps to see if it can operate normally.
