DGC-CO Series
DGC-CO Heavy-Load Component Strain Wave Gearset, Oldham Input
- Type
- Heavy-load component set (CO), Oldham input
- Models
- 14 - 40 (6 sizes)
- Reduction Ratios
- 50 - 160
- Rated Torque
- 7.0 - 382 Nm
The DGC-CO is the heavy-load counterpart of the DSC-CO component set: the same three-part strain wave gearset of wave generator, cup type flex spline and ring type circular spline, uprated for 30% higher torque load. The elliptical wave generator flexes the slim flex spline into the circular spline, packing high reduction ratios into very little space. It ships as bare components, not assembled or lubricated and with no crossed roller bearing, ready to build into robot joints and precision axes.
For standard torque duty, DSC-CO is the same component gearset without the heavy-load rating. View DSC-CO Series →

Series tiers
The second letter of the type code picks the tier; the heavy-load DGC shares the standard set's ratios but has no model 11.
- S Standard (DSC/DSH) — The base tier
- G Heavy load (DGC/DGH) — Higher torque load and life than the DSC type (this series)
- T Thin (DTC/DTH) — Thinner than the DSC type
Module types
- C Component — Gearset only, build your own joint (this series)
- P Combination — Output bearing included, takes axial and radial load
- A Sealed — Completely sealed unit
Input types
- O Oldham coupling — Self-aligning input, the CO standard
- H Hollow shaft — Cables and air lines through the axis
- J Solid shaft — Direct solid-shaft input
- E/R/Q Flat · Rigidity · Quick install — Special input executions
Customized executions
- M High tilting moment — Reinforced against moment loads
- L Lightweight — Weight-reduced execution (see DGC-CE-L)
- S Surface treatment — Environmental protection
- C Customized — Built to customer requirement
Lubrication
DATORKER units ship prepacked with HIWIN G11 except the CO and CE-L component types, which are filled at assembly to the chapter's quantities (5.5 to 145 g by model and mounting orientation).
- G11 HIWIN G11 reducer grease — 400 g tube; do not mix with other greases

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.
