Series 13

Three-row roller slewing bearing

Three separate raceways: two axial rows and one radial row. The highest load capacity we make, and the standard choice above two metres.

Structure

What the structure gives you

Splitting the load paths lets each raceway be optimised: the upper and lower rows take axial load and moment in both directions, the vertical row takes radial load. Capacity per unit of diameter is the highest in the range.

  • Independent raceways for axial, radial and moment load
  • Highest capacity per unit of diameter
  • Preferred for continuous rotation and fatigue-limited duty
  • Available with hardened gear teeth for pinion drive
  • Split design possible for retrofit around a column

Typical equipment

Ship unloaders, stackers and reclaimers, ladle turrets, deck cranes, mining equipment and large excavators.

Options you can add

  • Marine paint system
  • Grease purge ports for wash-down
  • Split ring for retrofit
  • Stainless hardware
  • Third-party witness inspection

Outside diameter, bore, mounting holes, gear module and the load case are enough for a quote. If you are replacing an existing ring, the old part number also works.
