A slewing bearing or slew[ing] ring is a rotational rolling-element bearing or plain 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. (To "slew" means to turn without change of place.)
The Thin Section Slewing Bearing has the same structure with ordinary slewing bearing,but the weight is light,and rotate flexibly.
We have provided slewing bearings for Sewer and Jetting Truck manufacturer, below are the pictures of real application.
