Bearing Repair Program

HGB expertise in bearing design and manufacturing has established HGB as the leading slewing ring remanufacturer in the world. We repair bearings as small as 200mm and as large as 6800mm.

Engineering expertise and cost savings

Our approach to bearing remanufacturing mirrors our manufacturing effort. HGB’s experienced remanufacturing staff is supported by expert engineers and dedicated, state of the art equipment.

Our bearing remanufacturing process has been designed to return the bearing to service in the shortest possible time and ensure the highest quality workmanship. A bearing repaired by HGB performs as new, at a lower cost than a new unit, and carries a one-year warranty.

HGB remanufacturing offers a variety of benefits, including:

Free inspection on slewing ring bearings up to 6800mm in diameter.

One week or sooner inspection time.

Non-destructive testing performed on all bearings.

Engineering analysis on all bearings.

Formal analysis reports provided for all inspections.

Substantial savings versus the cost of a new replacement bearing.

Stringent ISO 9001:2008 quality program.

Four week turnaround time for bearings 1.5m and under, and just a few additional weeks for bearings over 3m in diameter.

▲ Emergency remanufacturing services

▲ One year warranty for all remanufactured bearings

▲ New replacement bearings available

Most types of bearings, from any OEM

HGB can remanufacture any ball bearing or roller bearing, including thrust, radial, cross roller, double row, three row, four point contact, and cylindrical roller, regardless of the original manufacturer. If a bearing is beyond repair, HGB can reverse-engineer and manufacture a new replacement. operators can enjoy significant cost savings.

Our Process

1.Initial inspection

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

2.Disassembly and cleaning

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

3.Non-destructive testing

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

4.Repairability assessment

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

5.Precision grinding

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

6.Assembly

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

7.Final inspection

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

8.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.
