Product Description
The HS-14-I Strain Wave Gear Reducer is a high-precision harmonic drive gearbox engineered for compact robotic and automation systems requiring high torque density and ultra-low backlash.
With a diameter of 70 mm and thickness of only 29.5 mm, this reducer delivers exceptional performance in space-constrained applications. The flexspline is manufactured using advanced heat treatment processes and ultra-fine ADI materials to ensure superior fatigue strength, durability, and vibration damping.
The S-tooth harmonic design improves meshing contact, reduces friction, and enhances transmission smoothness. Designed for precision motion systems, the HS-14-I provides reliable positioning accuracy and long service life.
