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.
