About this product

Laifual FHG is a precision harmonic reducer. This record represents the manufacturer's U-III assembly in frame size 40, as identified in its model-specific dimensional drawing. Specifications preserve the listed reduction-ratio configurations, separate rated, starting/stopping and instantaneous torque limits, input speeds, backlash, mass and design-life qualifiers. Manufacturer drawing and web-table discrepancies are flagged in the affected specification conditions. Cover image: Manufacturer series image; size may vary.

Source-backed claims. Configuration, workload and evidence type matter when comparing products.

Allowable average input speed

3,500 r/min

Reported claim

Configuration: FHG; U-III; frame size 40; reduction ratio 100:1; Average input speed under grease lubrication. Unresolved manufacturer-source conflict: this drawing states 3500 r/min; the current family web table states 3000 r/min (https://www.laifual.com/fhg/). Both published claims are retained; neither is treated as a correction.
