Cross Roller Slewing Bearing

MC crossed roller slewing ring is mainly made up of inside and outside rings. It features compact in design, light in weight, small in assembling clearance, and high in installing precision. As the rollers are crossed arranged by 1:1, it is suitable for high precision mounting and capable to bear axial force, radial force and resultant torque simultaneously.

Three types of this kind of single row crossed roller slewing bearing:

A. Without gear bearing (non tooth)
B. External gear bearing (external tooth)
C. Internal gear bearing (internal tooth)
