Slewing Bearings
Also called turntable bearings or slewing rings, slewing bearings handle heavy loads and enable smooth 360° rotation, ensuring precise, reliable pivoting.
Slewing bearings are precision-engineered to support axial, radial and tilting moment loads in a single, compact assembly. This makes them ideal where space, strength and rotational accuracy all matter.
Each bearing typically consists of an inner ring and an outer ring with integrated raceways. This design allows them to:
- Handle combined load directions simultaneously
- Maintain stable rotation under high load
- Support precise positioning and smooth movement
Load capacity varies depending on diameter, gear configuration, raceway design and material selection — allowing the right solution to be specified for each application.
Why Use Slewing Bearings?
- High load capacity – Supports heavy axial, radial and moment loads in one unit
- Smooth 360° rotation – Enables controlled slewing around a central axis
- Compact design – Replaces multiple bearing arrangements
- Positioning accuracy – Ideal for equipment requiring controlled movement
- Versatile integration – Suitable for hydraulic, electric and mechanical drive systems
Applications
- Construction & lifting: Excavators, cranes, boom/man lifts & compactors
- Industrial & automation: Concrete pumps, carousels & rotary/robotic turntables
- Precision & energy: Manipulators, positioners, radars, wind turbines & solar trackers
