SDE
SDE low-backlash slew drive
The smallest envelope in the range, built for instrument-grade rotation: low backlash, low torque ripple, quiet running.

Structure
What the structure gives you
A reduced ring section, a lapped worm pair and a machined housing give a drive that moves smoothly in small increments. It is the option for instruments and small robots rather than for moving structures.
- Low backlash from a lapped worm pair
- Smooth motion at small increments
- Low noise for laboratory and medical use
- Light weight for moving gantries
- Stepper and servo input options
Typical equipment
Instruments, laboratory positioning, small robot joints, optical mounts and medical imaging gantries.
Options you can add
- Lapped worm pair
- IP65 sealing
- Custom mounting flange
- Vacuum-compatible grease

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.
