Product Description


SYHG-Ⅰ Series Harmonic Drive
Hollow Shaft Flanged Structure | Large Passage | Fully Sealed

Product Overview
The SYHG-Ⅰ Series features a hollow, flanged, standard-structure flexspline. A large-diameter hollow shaft passes through the center of the wave generator cam. The reducer incorporates internal support bearings and a fully sealed design for easy installation — making it especially suitable for applications where cables or other components must pass through the center of the reducer.

 SYHG-Ⅰ Series Harmonic Drive

Key Features

  • Cup-Type Standard Structure
    Proven, robust design with strong mounting compatibility for easy system integration.

  • Zero Backlash
    Gear engagement without backlash eliminates lost motion and improves control response.

  • Coaxial Input & Output
    Simplifies the drivetrain and reduces installation space.

  • High Positioning & Rotational Accuracy
    Delivers excellent angular precision and repeatability for demanding positioning tasks.

Typical Application Scenario
Rigid circular spline fixed, flexspline as output – ready for integration into robotic joints, rotary tables, and precision positioning systems.
