Harmonic servo-gearbox SHD-03 series

coaxialsolid-shaft0 - 0.1 Nm

Introduction
The SHD-mini series harmonic drive is engineered for applications requiring minimal volume and weight. It features a top-hat style flexspline, reduced axial dimensions and a pre-assembled modular form factor for immediate integration. The main bearing uses compact four-point contact ball bearings to directly support external loads, and shaft bores can be customized to match motor shafts. Select motor models according to your mechanical design constraints.

Key features

• Compact axial dimensions and lightweight construction
• Top-hat style flexspline for reduced profile

• Compact four-point contact ball bearings for direct load support
• High rotational accuracy and low backlash (typ. ≤20 arcsec; certain sizes ≤10 arcsec)
• Coaxial input/output configuration
• Customizable shaft bore to fit motor shafts
