High precision Single Row Cross Roller Slewing ring with Internal Gear

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.)

Slewing bearings often use two rows of rolling elements. They often use three race elements, such as an inner ring and two outer ring "halves" that clamp together axially.

The Single row  crossed roller slewing bearing is composed of two seat rings,which design in compact  structure and light weight, the clearance is small when assembly, so need high precision .The roller  are 1:1 cross arranged, it can bear the axial force,tilting moment and relatively large radial force. It is widely used for hoisting,transportation,construction machinery,and the military products.
