what is a crossed roller bearing slewing ring bearings
Slewing Ring Bearing Types Characteristics and Applications
Crossed roller slewing ring is composed of two bearing rings has a compact structure high manufacturing accuracy and small assembly clearance The rollers are arranged crosswise can support axial force tilting moment and relatively large radial force at the same time

EXU Crossed Roller Slewing Bearings
EXU series needs no flange or support base for installation because of its outer and inner rings having mounting holes In addition since the outer ring and the inner ring are both integral structures almost no difference will be made on its performance it will provide stable rotation accuracy and torque which is applicable to rotating parts of the outer ring and inner ring
Slewing bearing
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 (To slew means to turn without change of place ) Compared to other rolling-element bearings slewing bearings
