DSH-PO Series
DSH-PO Combination Strain Wave Gear Unit, Oldham Input
- Type
- Hollow-spline gear unit with output bearing (PO)
- Models
- 14 - 40 (6 sizes)
- Reduction Ratios
- 50 - 160
- Rated Torque
- 5.4 - 294 Nm
A wave generator, hollow-type flex spline and ring-type circular spline deliver high reduction ratios in a single compact stage, and the DSH-PO packages them as an Oldham combination unit with a crossed roller bearing included, so the output withstands axial and radial loads directly. It arrives assembled and lubricated, and the input shaft is self-aligning.
Need 30% more torque from the same Oldham combination unit? DGH-PO is the heavy-load build. View DGH-PO Series →
