Cross Roller Slewing Bearing

The internal configuration consists of cylindrical rollers in a v-shaped groove in each ring. The rollers are oriented with alternating axes of rotation. Positioned in this manner, the bearing accepts all combinations of radial, thrust, and moment loads. Rotational torque is less than a four-point contact ball design because each roller only transmits load in a single direction, and the greater contact area and geometry of a roller versus a ball provides a higher degree of stiffness and rigidity.

Depending on their design, slewing bearings have the following features:

• High load carrying capacity
• High stiffness for rigid bearing application
• Low friction
• Long service life
• Surface protection and corrosion resistance
• Integration of additional features, including:
  • Driving mechanism
  • Control devices
  • Lubrication systems
  • Monitoring systems
  • Sealing cassettes
