Three-Row Cross Roller Slewing Ring Bearing

The TR series bearing has three independent rows of rollers oriented normal to the direction of loads being transmitted through the bearing. Their orientation is selected to optimize capacity, provide low frictional resistance and minimize deflection.The top and bottom rows of rollers transmit any opposing thrust loads and combine to transmit any moment loading, while the middle row transmits any radial loads. The rollers, the separator configuration used for each, and the mating raceways are sized to meet load or other application requirements.

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
