Overview
The Zhixing MINI series is a compact harmonic gear reducer for small rotary mechanisms, robot-joint prototypes and precision motion assemblies. Choose a MINI8 or MINI11 reducer with flange or shaft output, then select an available reduction ratio.
These are mechanical reducers for integration with a separate motor. The series is presented for 35 mm and 42 mm stepper-motor integration, with MINI8 and MINI11 respectively; verify the input coupling and mounting dimensions before selecting a motor. A motor, driver and controller are not included. The Flange Plate option is a separate accessory, not a complete reducer.
Features
- Compact coaxial harmonic reduction for space-limited rotary axes.
- MINIF flange-output and MINIS shaft-output choices.
- Actual available combinations include 30:1, 50:1, 80:1 and 100:1 ratios; availability depends on size and output style.
- Metal housing and mounting interfaces for integration into custom mechanisms.
- Dimensional and sectional references for the MINIF8 and MINIF11 flange models.
Selection Guide
| Size / Item | Output | Available ratios |
|---|---|---|
| MINI8 | Flange / Shaft | 30:1, 50:1, 100:1 B |
| MINI11 | Flange | 30:1, 50:1, 80:1, 100:1 |
| MINI11 | Shaft | 30:1, 50:1, 100:1 |
| Flange Plate | Accessory | Not applicable |
The B suffix identifies the listed 100:1 MINI8 configuration. Do not assume its mounting dimensions match the illustrated standard MINIF8 drawing. Only the combinations listed above are offered.

Dimensions above apply to the illustrated MINIF flange models. They do not define the shaft-output or 100:1 B versions. Use the complete drawing to check hole positions, fits and thread depths. Output speed equals motor input speed divided by the selected reduction ratio. Match motor speed, load and duty cycle to your mechanism; no numerical torque or backlash rating is specified here.
Applications
- Small robot joints and compact robotic arms.
- Rotary positioning mechanisms, laboratory fixtures and custom automation prototypes.
- Compact transmission development where reduced output speed is required.
What's Included
Reducer option: one harmonic reducer in the selected size, output style and ratio. Flange Plate option: one separate flange plate accessory only. Series and comparison photographs can show multiple parts; they do not represent a multi-unit package. Motors, stepper drivers, controllers and mounting fixtures are not included.
FAQ
Is this a complete stepper motor assembly?
No. This listing supplies a mechanical reducer, or the separate flange plate accessory when that option is selected. A compatible motor and drive electronics are required separately.
Can I use the same drawing for every option?
No. The drawings cover the MINIF8 and MINIF11 flange models. Check the actual interface for shaft-output and 100:1 B versions before machining mating parts.
What changes when I select a higher ratio?
At the same motor speed, a higher reduction ratio produces lower output speed. A ratio alone does not establish an allowable load or torque rating.
