Our process

Initial inspection
Inspection and documentation of turning torque, free-state clearance, gear size, and external features.

Initial inspection

 

Disassembly and cleaning
Bearings are disassembled and the races, rolling elements, and spacers are cleaned.

Disassembly and cleaning

 

Non-destructive testing
Races undergo visual or magnetic particle inspection to detect cracks or defects. Hardness readings are recorded.

 

Repairability assessment
The service department reviews each bearing, application, and test result to determine repairability.

Repairability assessment

 

Precision grinding
Bearing races are precision-ground to the proper geometry to optimize the bearing load-carrying capability.

Precision grinding

 

Assembly
The bearing is assembled with new rolling elements and seals, and packed with lubricant.

Assembly

 

Final inspection
All critical features are inspected and documented. The bearing is approved by quality control before shipment.

Final inspection

 

Manufacture
If at any time during the maintenance process, maintenance does not meet the specifications required by HGB, replacement seat rings or new slewing bearings can be manufactured. Product user can use our replacement slewing bearing to save a lot of costs.
