After proper maintenance and use, the life of the repaired slewing ring is equal to or greater than the life of the new slewing ring. The key is an effective preventive maintenance program that removes the slewing bearings from the equipment for repairs before severe wear and tear occurs. Most single-row four-point contact ball slewing bearings, multi-row ball slewing bearings, cylindrical roller slewing bearings, tapered roller slewing bearings, and thin cross-section slewing bearings with diameters from 8 “to 20” can be economically serviced and remanufactured. This approach can not only significantly reduce downtime, but also reduce replacement and inventory. In addition, remanufacturing provides products that meet or exceed new equipment standards.
Typically, slewing bearings are remanufactured within a two – to three-week delivery cycle at half the cost of a new replacement. In case of emergency, Xuzhou Fenghe Slewing Bearing may provide 24-hour maintenance service. If the slewing ring is deemed beyond repair by the technical engineer, a new replacement may be provided. The process begins with a thorough inspection of the slewing bearings. The specific repair and remanufacturing process is as follows:
