Overview
The Zhixing ZXS series harmonic gear reducer provides compact mechanical reduction for robot joints, positioning mechanisms and precision automation. Choose a complete model code to match the frame size, reduction ratio and mounting configuration of your design.
Features
- Compact harmonic reduction mechanism with a circular mounting flange.
- Six selectable frame sizes, with ratios from 30:1 to 120:1 depending on size.
- Machined metal housing and multiple mounting points for integration into custom motion assemblies.
- Distinct model codes preserve the selected mechanical configuration.

Configuration Guide
In a code such as S14-50-8-3, S14 identifies the size family and 50 identifies the 50:1 reduction ratio. Preserve the complete suffix when matching your mounting design. The available combinations are listed below; other series sizes and ratios shown in reference material are not included in this listing.
| Size | Available ratios | Reference outer diameter (mm) | Reference overall length (mm) | Model suffix |
|---|---|---|---|---|
| S14 | 30, 50, 80, 100 | 73 | 36 | 8-3 |
| S17 | 30, 50, 80, 100 | 79 | 39 | 8-3 |
| S20 | 30, 50, 80, 100 | 93 | 41 | 14-5 |
| S25 | 30, 50, 80, 100, 120 | 107 | 49 | 14-5 |
| S32 | 30, 50, 80, 100, 120 | 138 | 60 | 19-6 |
| S40 | 80, 100 | 160 | 70 | — |
Reference envelope dimensions correspond to the ZXS size drawings below. Confirm the complete model, input interface and mounting dimensions before machining adapters or selecting a motor. Do not treat these envelope dimensions as a universal motor compatibility specification.
Applications
These gear reducers suit custom robot-joint transmissions, robotic arms, positioning equipment, packaging machinery, machine tools and other precision motion mechanisms. Application equipment shown in the images is illustrative and is not included.
What's Included
One harmonic gear reducer in the selected model configuration. Motors, drives, controllers, robots and demonstration equipment are not included.
FAQ
Does this include a servo motor or controller?
No. This is the mechanical reducer. Select the motor, coupling and controller separately to suit your installation.
Can I select any ratio for any frame size?
No. Select one of the listed complete model codes. S25 and S32 include a 120:1 option; S40 is listed with 80:1 and 100:1 options.
What should I check before designing an adapter?
Match the full model code, shaft or bore interface, pilot diameters, bolt pattern and installation depth. The drawings provide size references and do not establish compatibility with every motor.
Visual Details
Engineering drawing legend: Ø denotes diameter; THRU denotes a through-hole; the depth symbol precedes a blind-hole depth. The Chinese hole-pattern annotations mean equally spaced and through-hole, respectively. Original drawing annotations are retained to preserve the engineering facts. A comma in a dimension denotes a decimal separator. Match the selected configuration before fabrication.
