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.

Slewing Bearing Installation - Loyal Slewing Crane Bearing

The information is valid for single row slewing bearings used in typical appliions. Mounting should, wherever possible, be carried out in a dry, clean environment. When slewing bearings have to be mounted in an unprotected area, which is often the case, steps should be taken to protect the bearing and its associated components until installation is complete.
