HSS Series Harmonic Drive Gearbox Φ138mm Ratio 50:1 Backlash 20arcsec 19mm Input Diameter

This harmonic gearbox has a gear ratio of 50, a frame size of Φ138mm and an input shaft diameter of 19mm and a maximum backlash of 20arcsec.
The HSS series harmonic gearboxes have a flexspline structure in the form of a standard drum and highly rigid, full-roller cross bearings that can be used directly to support external loads and are characterized by high functionality, high speed and high mobility.
The simple structure with high rigidity and low backlash makes it possible to withstand high torques and achieve excellent positioning and rotation accuracy. This harmonic gearbox is widely used in robots, CNC machine tools, textile machines, printing machines, packaging machines and other fields.
