Product Description
The HS-32-II Hollow Shaft Harmonic Drive Reducer is a high-performance strain wave gearbox engineered for industrial robotic joints, collaborative robots, and precision automation systems requiring high torque density and ultra-low backlash.
With a 147 mm outer diameter and 65.1 mm compact axial length, this reducer provides exceptional torsional rigidity and load capacity while maintaining precise positioning accuracy.
Its hollow shaft design allows convenient cable routing, sensor integration, and compact joint assembly, making it ideal for humanoid robots and multi-axis robotic arms.
Manufactured using ultra-fine Austempered Ductile Iron (ADI) materials, advanced heat treatment technology, and innovative S-tooth profile geometry, the HS-32-II delivers superior fatigue resistance, vibration damping, and long-term operational stability.
Designed for demanding servo-driven systems, this model ensures smooth transmission, reduced friction, and extended service life even under high dynamic loads.
