Bearing selection for low-speed appliions | Kaydon Bearings white papers - Thin section bearings, slewing ring bearings, bearing …

Low-speed bearings defined. The dynamic conditions dictating the bearing design are indied by the linear speed at the bearing pitch line, or the pitch line speed. Pitch line speeds of less than 500 fpm are generally considered low speed, and 500 fpm to 3,000 fpm are mid-range. Anything higher than 3,000 fpm is considered high-speed.

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.
