Series 011
Four-point contact ball slewing bearing
One raceway, four contact points. The four-point contact ring carries axial load, radial load and tilting moment in the lowest section height of any structure in our range.

Structure
What the structure gives you
A single gothic-arch raceway takes the ball in four points, so the same ring absorbs push, pull and overturning moment. It is the lightest and most compact option, which is why it dominates mobile equipment.
- Axial, radial and moment load through one raceway
- Compact section height keeps the machine low
- Balls circulate freely: low starting torque
- Available geared on the outside or inside diameter
- Cost-efficient at medium capacity
Typical equipment
Turntables, aerial work platforms, small and medium cranes, excavator swing circles, robot bases and positioning tables where height and weight matter.
Options you can add
- Viton seals for high temperature
- Split ring for assembly around a column
- Stainless grease nipples
- Preloaded version for zero-backlash positioning
- Gear teeth induction hardened separately

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.
