Small size harmonic drive reducer for compact precision motion systems, offering high reduction ratio, near-zero backlash, low weight and accurate transmission.

The FHG-III series harmonic drive features a large hollow shaft structure. It adopts an integrated sealed flange design that combines harmonic drive components into a single unit, pre-filled with specialized lubricating grease for simplified equipment assembly. A high-rigidity cross roller bearing (main bearing) is integrated internally. This system is typically configured with either fixed circular spline and flexspline output or fixed flexspline and circular spline output.
