DSC-PO Series
DSC-PO Combination Strain Wave Gear Unit with Output Bearing
- Type
- Combination unit (PO): Oldham input, crossed roller output bearing
- Models
- 14 - 40 (6 sizes)
- Reduction Ratios
- 50 - 160
- Rated Torque
- 5.4 - 294 Nm
The DSC-PO packs the DATORKER strain wave mechanism, a wave generator flexing a cup-type flex spline inside a flange-type circular spline, into a unit that arrives assembled and lubricated. A crossed roller bearing is built into the output, so the gear takes axial and radial load directly while delivering the high single-stage ratios of the strain wave design.
Need 30% more torque from the same cup-type unit? DGC-PO is the heavy-load build. View DGC-PO Series →

Models & ratios
Rated torque is at 2,000 rpm input; peak torque covers start and stop. Ratios 120 and 160 are not available on the smallest models. A customized code is appended where used, e.g. DSC-25-80-PO-C.

Series tiers
The second letter of the type code picks the tier; the PO combination module comes in standard and heavy load.
- S Standard (DSC-PO) — The base tier
- G Heavy load (DGC-PO) — Higher torque load and life than standard
Customized executions
The trailing code of the model number; blank means standard.
- M High tilting moment (DSC-PO-M) — Higher loading capacity of the output bearing
- L Lightweight — Weight-reduced execution
- S Surface treatment — Environmental protection
- C Customized — Built to customer requirement
