Introduction
The CSF-mini series miniature harmonic drive is developed for applications with specialized volume and weight requirements, utilizing a cup-style flexspline. This series offers pre-assembled modular products for immediate use. The main bearing uses compact four-point contact ball bearings to directly support external loads. The CSF-mini series includes two types: motor-mount type (2XH) and shaft-input type (1U), which supports input forms such as belts, gears and couplings. Select the model and ratio that match your mechanical design requirements.

Features

• Compact size and lightweight construction
• Streamlined, space-saving cup-style flexspline
• High rotational accuracy and positioning precision
• Coaxial input/output configuration for simple integration
• Pre-assembled modular units for fast installation
• Main bearing: compact four-point contact ball bearings for direct external load support
