Overview
INFRANOR harmonic (strain wave) reducers provide high single-stage reduction ratios with compact footprints. Equipped with the patented SP gear-tooth profile, they deliver increased rigidity and minimized backlash. Available in hollow shaft (large aperture), solid shaft and rigid-joint variants to suit robotic systems, CNC machine tools, aerospace subsystems and other industrial applications requiring compact, accurate reduction solutions.

Key features

• Reduction ratios: 50 to 160
• Weight and volume savings: up to 50% vs. standard gears
• Transmission accuracy: down to 50 arc-seconds; repeated positioning 5 arc-seconds
• SP gear profile: +10% rigidity, +20% transmission accuracy
• Max input speed: up to 8,500 RPM (peak) / up to 3,500 RPM (continuous)
• Output torque: up to 840 Nm (typical peak example); series peaks up to 2,483 Nm (standard-flex)
• Special lubricating grease reduces noise, temperature and wear
• Service life: L10 = 10,000 h; L50 = 50,000 h
