DGH-AH Series
DGH-AH Hollow Sealed Strain Wave Gear, Heavy Load Series
- Type
- Completely sealed hollow-shaft unit (AH), heavy load
- Models
- 14 - 40 (6 sizes)
- Reduction Ratios
- 50 - 160
- Rated Torque
- 7.0 - 382 Nm
The DGH-AH packs the heavy-load DATORKER gearset (wave generator, hollow type flex spline and ring type circular spline) into a completely sealed unit with 30% higher torque load, putting high reduction ratios in less space. It ships assembled and lubricated, with a crossed roller bearing included on the output.

How buying works
Spec it in the configurator: drawings, 3D CAD, and a quote to follow.
HIWIN series are configured to your application, not bought off the shelf. Start from your loads and speeds if you are still choosing a size.
