Crossed Roller Slewing Rings
Crossed roller slewing rings are composed of two rings, have a compact structure, high manufacturing accuracy, and small assembly clearance. The rollers are arranged crosswise, and they can support axial forces, tilting moments and relatively large radial forces at the same time.
Available with inner gear, outer gear or no gear
Very high rigidity
Equipped with sealing and lubrication system
Dimensions and Tolerances
Clearance for slewing rings is not standardized. ALPHA slewing rings can be supplied with different clearance or preload tolerances, based on the application type.
