cross roller

The cross roller slewing ring is composed of two ferrules, with compact structure, light weight, high precision and small assembly clearance. The rollers cross one by one, so that the slewing ring can bear high axial, radial and overturning moment loads. Single row crossed roller bearings are suitable for lifting equipment and other construction machinery.

• Outer diameter: 602mm~4726mm
• Ball Diameter: 25mm~50mm
• Rated load: 104kN~1980kN

Crossed roller slewing rings consist of square raceways and cylindrical rollers instead of balls. The complete contact of the rollers (compared to only 4 ball points) increases the load capacity of this type of bearing, especially for radial loads. This type of bearing also has less internal clearance than ball bearings, typically 0.0-0.03mm (preloaded) axial and radial. While this increases the starting torque, it also increases the precision and stiffness of the bearing, making it especially useful in precision applications.
