FHD

Product Overview

FHD Flexspline Gear

Compared to conventional designs, the FHD-I model reduces axial length by 50%, while the FHD-III achieves a 15% reduction, all without compromising product performance.

This compact and efficient configuration makes the FHD series an ideal choice for precision machinery, robotics, and automation systems requiring space-saving, high-torque, and reliable harmonic drive solutions

Compared to conventional designs, the FHD-I model reduces axial length by 50%, while the FHD-III achieves a 15% reduction, all without compromising product performance.
