HONPINE’s SHD and CSF series of ultra-small harmonic drives mark a breakthrough in compact harmonic drive technology. Comparable in size to a paperclip, these drives are available in four models (03, 05, 08, and 11), each offering multiple input/output configurations (shaft and flange) and gear ratios (30, 50, 80, and 100) to meet diverse torque and speed requirements—resulting in dozens of product variations.

The SHD-mini series harmonic drive is designed for applications with small volume and weight requirements, featuring compact axial dimensions and a top-hat style flexspline. This series exclusively supplies pre-assembled modular products for immediate use. The main bearing employs compact four-point contact ball bearings to directly support external loads. The shaft bore dimensions in this series can be customized to match specific motor shaft sizes. Select the most suitable motor model based on your mechanical design requirements.

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.
