What Is a Slewing Bearing?
A slewing bearing (also called slew ring bearing, slewing ring, or turntable bearing) is a large-diameter rolling element bearing that enables 360-degree rotation between two heavy structures while simultaneously supporting combined axial, radial, and moment loads. They range from 100mm to over 4,000mm in bore diameter and are found wherever heavy equipment must rotate — from cranes and excavators to wind turbines and solar tracking systems.
