Harmonic servo-gearbox SHD-08

coaxialmodularcompact

Introduction
The SHD-mini series harmonic drive is engineered for applications with strict volume and weight constraints, offering reduced axial dimensions and a top-hat style flexspline. This series provides pre-assembled modular units for immediate integration. The main bearing uses compact four-point contact ball bearings to directly support external loads. Shaft bore diameters can be customized to fit specific motor shafts. Choose the motor model suited to your mechanical design requirements.

Features

• Compact, lightweight construction
• Simplified, space-saving architecture
• Excellent rotational accuracy and positioning precision
• Coaxial input/output configuration
• Pre-assembled modular units for fast integration
• Customizable shaft bore for motor compatibility
