INFRANOR Harmonic Reducers

High reduction ratios meet accuracy & compactness

Our Harmonic or strain wave gears offer high reduction ratios in one stage.
They are equipped with our patented “SP gear-tooth profile”, offering high accuracy, rigidity and zero-backlash.
They are ideally suited for Robotic applications, CNC machine tools, aerospace applications and other key industries, whenever high reduction ratios are required, space is limited, and ease of installation is desirable.
Whether it is hollow shaft with large aperture, solid shaft, or rigid joint design, you are sure to find the right solution.

> Reduction ratios from 50 to 160
> Lightweight: up to 50% volume and weight reduction compared to standard gears
> Transmission accuracy down to 50 arc-seconds, repeated positioning 5 arc-seconds
> SP gear profile increases rigidity (+10%) and transmission accuracy (+20%)
> Max. speed up to 8’500 [Rpm] peak and 3’500 [Rpm] continuous
> Output Torque up to 840 [Nm] peak
> Special lubricating grease lowers noise, temperature, and wear
> Ultralong service life: L10: 10,000 [h]/ L50: 50,000 [h]
