Swing Bearing Also named Swing Circle, Slewing Ring, The slewing bearing of excavator realizes the rotation of the device by the action of friction and lubrication, which can drive the mechanical rotation and provide support capability in excavator.

A slewing bearing or slew[ing] ring is a rotational rolling-element bearing that typically supports a heavy but slow-turning or slow-oscillating load, often a horizontal platform such as a conventional crane, a swing yarder, or the wind-facing platform of a horizontal-axis windmill.
