Harmonic micro-gearbox CSF 03

coaxialpinion shaft0 - 0.1 Nm

Introduction
The CSF-mini series miniature harmonic drive is developed for applications with strict volume and weight requirements, using a cup-type flexspline. This series provides pre-assembled modular units for immediate installation. The main bearing uses compact four-point contact ball bearings to directly support external loads. Two configurations are available: motor-mount type (2XH) and shaft-input type (1U); the 1U accepts input by belts, gears or couplings. Select the suitable model based on your mechanical design constraints.

Features

• Compact footprint and lightweight construction
• Streamlined, space-saving structure
• High rotational accuracy and positioning precision
• Coaxial input and output arrangement
• Delivered as pre-assembled modular products
