A slewing bearing or slewing ring (also called a turntable bearing) is a rotational rolling-element bearing that typically supports a heavy but slow-turning or slowly-oscillating loads in combination (axial, radial and moment loads), often a horizontal platform such as a conventional crane, a swing yarder

Applications include heavy duty machinery, large excavators, cranes, mining equipment, wind turbines, and telescopes. XR series slewing bearings consist of cross rollers providing a high degree of stiffness and low rotational torque.

the slew drive's axial movement, or motion around its axis, interacts to create radial torque. The action occurs by meshing the grooves of the horizontal screw with the teeth of a perpendicular gear. While turning, the worm gear's axial movement transfers magnified torque force to the radial gear.

lifting equipment like cranes, slew rings create a joint between the undercarriage and the upper structure of the machine. These bearings allow cranes to turn 360 degrees while supporting other diverse movement requirements, from thrust and radial motion to tilting.
