Series 02

Double row ball slewing bearing

Two ball rows share the moment, so tilting capacity climbs above a single-row ring without going to rollers.

Structure

What the structure gives you

Two raceways with separate ball rows take the axial load and moment in both directions while a third path carries radial load. It sits between the four-point contact ring and the three-row roller in both capacity and cost.

  • Higher tilting capacity than a single-row ball ring
  • Lower friction than a roller structure
  • Good compromise where moment dominates but speed matters
  • Available with an eight-point contact option
  • Geared or plain

Typical equipment

Cranes, harbour equipment, concrete pumps, wind turbine yaw systems and general industrial turntables.

Options you can add

  • Eight-point contact option
  • Hardened gear teeth
  • Seal set for dusty environments

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.
