Triple-row roller bearing slewing rings (axial-radial roller bearings)

This design is the heavyweight among the slewing rings. It has three raceways, two axial roller races and one radial roller race. The linear load transmission enables significantly greater loads than with ball bearing slewing rings without demanding additional installation space. This does, however, mean significantly greater requirements in terms of the accuracy and rigidity of the connection assembly.

Available bearing designs:

  • Without teeth
  • With internal teeth
  • With external teeth

Example fields of application:

  • Hoisting, conveying and cargo handling systems
  • Extraction and mining equipment
  • Heavy construction site equipment and cranes
  • Offshore engineering
