TECHNICAL – QCB - Slewing rings

In service, slewing rings will usually wear at a linear rate, once this rate accelerates this is a sign that the bearing is reaching the end of its service life. As a “rule of thu”, once the measure deflection exceeds 1.5x the original value then plans should be set into motion to procure and replace the ring.

How to tell when a slewing ring bearing needs to be

As clearance increases, wear is usually accelerated, making close monitoring critical. The play, or clearance, in a slewing ring bearing is another important indior of a problem. A new bearing is asseled with a specific amount of clearance to compensate for slight out-of-flatness encountered in a mounting structure.
