Slewing drives for almost any application
Worm-gear slewing drives that carry axial, radial and moment loads while delivering high rotational torque. Tilting moment capacity from 1,100 N·m to 1,600 kN·m (811 to 1,180,160 lbf-ft), 61 models, and 207 configurations designed so far, with new designs added often.
- Single and double worm drives
- Hydraulic motors, 12, 24 or 48 V DC gear motors, or SEW-EURODRIVE and NORD AC gear motors integrated in-house
- Built to mate with your own gearbox or motor

Ratings are maximum values. Can't find a drive that fits? Our engineers design slewing drives for specific applications. New designs are added often.
Mounting and valve options
Top plate: DB, LB or none
- DB: top plate with through holes; slewing ring with threaded holes.
- LB (recommended): no top plate; slewing ring with counterbored and threaded holes. DB and LB are fully interchangeable.
- No code: no top plate and no counterbore; direct holes.
Hydraulic drives: Z1 or Z2
- Z1 (recommended): hydraulic motor with a counterbalance valve fitted.
- Z2: hydraulic motor without the valve, with the interface for a valve assembly.
