HHD Series Harmonic Drive Gearbox Φ80mm Ratio 100:1 Backlash 20arcsec 8mm Input Diameter

This harmonic gearbox has a gear ratio of 100, a frame size of Φ80mm and an input shaft diameter of 8mm and a maximum backlash of 20arcsec.
The HHD series harmonic gearboxes use an ultra-thin hollow flange structure flexspline, the axial length is shortened by about 50% without changing the product performance. The output side is equipped with a high-rigidity crossed roller bearing.
Characterized by an ultra-flat design, lightweight, and compactness, this series is widely used in humanoid robots, metal machine tools, medical equipment, communication equipment, etc.

Key Feartures
