Cross Roller Slewing Bearing
Cross Roller Slewing Bearing
Compact structure with high rigidity, high precision and constant rotational resistance

Cross-roller bearings are made up of a squared raceway and cylindrical rollers instead of balls. The full contact of the rollers (versus just 4 points of the balls) increases the load capacity of this style bearing, especially for radial forces.
​
This style bearing also has a tigher internal clearance than ball bearings, with axial and radial clearances typically from 0.0-0.03mm (preloaded). While this increases the starting torque, it also increases the accuracy and rigidity of the bearing, making it especially useful in precision applications.
