Cross Roller Slewing Bearing

Cross Roller Slewing Bearing

Compact structure with high rigidity, high precision and constant rotational resistance

Cross Roller(2).png

Cross roller slewing bearings are primarily used when a single row ball slewing bearing does not meet operating performance requirements for high stiffness, high precision, as well as rotation torque. The clearance is usually smaller than single row ball slewing bearing, from 0-0.03mm (preload). Because the rollers are 1:1 cross arranged, this compact structure is capable to bear axial force, tilting moment and much more radial force.
