Technical Specifications
Industrial Application

Slewing ring bearings are large-size rolling bearings that can accommodate axial, radial and moment loads acting either singly or in combination and in any direction. They can perform both slewing (oscillating) movements as well as rotational movements. A slewing ring bearing consists of an inner ring, an outer ring and rolling elements (balls or cylindrical rollers) separated by polyamide spacers.

Compared to traditional pivot arrangements, slewing ring bearing arrangements provide many design and performance advantages. The compactness and large inner diameter simplify the design of the bearing arrangement and its associated components.

Application Areas

  • Access platforms & Ladle turrets
  • Cranes of all types (Port, Tower, Off-shore)
  • Excavators (Small, Medium, Large)
  • Solar heliostat Tracking Systems
  • Robots & Palletizing systems
  • Tunnel boring machines & Wind energy
