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

The general tolerances of slewing rings conform to ISO 286-1 and ISO 286-2. The boundary dimensions of slewing rings are not standardized. Please contact our technical department to get our slewing rings catalogue.

Bearing Clearance or Preload

Clearance for slewing rings is not standardized. ALPHA slewing rings can be supplied with different clearance or preload tolerances, based on the application type.
