Product range
Slewing bearings, slew drives and gear parts
Four product families from one engineering contact: slewing rings that carry the load, slew drives that turn it, spur gear drives for higher ratio and torque, and the gear and custom parts that go around them.

Choose by function
| Slewing bearing | Slew drive | Spur gear drive | |
|---|---|---|---|
| What it is | A geared or ungeared slewing ring | Ring inside a sealed worm-gear housing | Ring plus spur gear reduction stage |
| Load path | Axial, radial, tilting moment | Same plus drive torque | Same plus higher torque |
| Motion | Free rotation, you add the drive | Self-locking worm rotation | Non-self-locking, brake needed |
| Motor | Separate gearbox or pinion | Direct flange, DC / AC / servo / hydraulic | Motor with brake + encoder |
| Best for | OEM building its own drive train | Trackers, cranes, platforms | Heavy turntables, machine tools |
