Harmonic gear reducer CSF 08

coaxial0.5 - 1 Nm1 - 5 Nm

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 exclusively offers pre-assembled modular products for immediate use. The main bearing employs compact four-point contact ball bearings to directly support external loads. The CSF-mini series includes two types: the motor-mount type (2XH) and the shaft-input type (1U) that supports input forms such as belts, gears, and couplings. Select the most suitable model based on your mechanical design requirements.
