FHN

About this product

Laifual FHN is a hollow harmonic transmission reducer. This record identifies the U-III assembly in frame size 25, explicitly named in the manufacturer's FH-family specification table. The FHN page supplies rated and peak torque limits, input-speed limits, backlash, design-life figures and the distinct mass of its III assembly. Ratio-dependent values remain separate configurations in Specifications. Cover image: Manufacturer series image; size may vary.
