Slewing ring repair and refurbishment

Slewing ring repair and refurbishment


Slewing ring refurbishment can offer significant savings when compared to a replacement slewing ring. Repair or refurbishment is usually only economic on slewing ring with large bore size and depends on the degree of wear or damage. Repair on smaller slewing rings is possible, but only becomes economic on larger batch sizes.

Certain types of damage are easy to repair, such as minor surface scuffing or light staining. Moderate surface conditions, such as corrosion, indentation of fine spalling, and more difficult tpo repair and will probably require raceway grinding. Also some bad condition we have to change the rollers/balls and cage, re-grinding on the raceway and surface. It all depends on the status of the slewing rings.
