Harmonic servo-gearbox SHD-11

coaxialcompactmodular

Introduction
The SHD-mini series harmonic drive is designed for applications requiring minimal volume and weight. It features reduced axial dimensions and a top-hat style flexspline and is supplied as a pre-assembled modular unit ready for integration. The main bearing uses compact four-point contact ball bearings to directly support external radial and axial loads. Shaft bore dimensions can be customized to fit motor shaft sizes; select a compatible motor model according to your mechanical design.

Features

• Compact axial profile and low mass
• Pre-assembled modular construction for plug-and-play integration
• High rotational accuracy and positioning precision
• Coaxial input/output configuration for straightforward coupling to motors
• Main bearing supports external loads directly (four-point contact ball bearings)
