DSC-PO Series
Combination Strain Wave Gear Unit with Output Bearing
DATORKER® Strain Wave Gearing Systems
DSC-PO-M Series
DSC-PO-M Combination Strain Wave Gear Unit, High Tilting Moment
- Type
- Gear unit with high tilting moment output bearing (PO-M)
- Models
- 14 - 40 (6 sizes)
- Reduction Ratios
- 50 - 160
- Rated Torque
- 5.4 - 294 Nm
The DSC-PO-M packs the DATORKER wave generator, cup-type flex spline and flange-type circular spline into a combination unit with the crossed roller bearing included, delivering high reduction ratios in little space. As the Oldham combination type, the input self-aligns to a motor shaft of Ø6 to 14 mm (H7 bore), easing motor mounting, while the output bearing withstands axial and radial load with a higher tilting moment.

Models & ratios
Rated torque is at 2,000 rpm input; peak torque covers start and stop. Ratio 120 starts at model 17 and ratio 160 at model 20; torque ratings are shared with the other standard cup-type modules, so the M unit gives up nothing for its larger bearing.

The configurator assembles this number for you, with drawings and 3D CAD. Configure ↗
Module executions
PO-M sits in the standard cup-type (DSC) family; the module and input letters pick how much of the joint comes built.
- CO Component set — Bare gearset, self-assembly required
- PO Combination — Output bearing included, standard capacity
- PO-M High tilting moment — This unit: enlarged output bearing
- AJ-M Solid shaft, high tilting moment — Same enlarged bearing, solid input shaft
Mounting flanges
Two flange executions cover both assembly sequences; the catalog publishes dimension tables for each.
- A Type A — Flange to the motor first, reducer body last
- B Type B — Reducer body to the flange first, motor last
Lubrication
Units ship prepacked with HIWIN G11 reducer grease (lithium soap thickener, mineral base oil, -20 to 130 degrees C service temperature).
- G11 HIWIN G11 — Do not mix with other greases; 400 g tube for replacement

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.
