HS / HSG / HD Hat-Type Harmonic Reducers
HS / HSG / HD Hat-Type Harmonic Reducers
Hat-type harmonic reducers for robotic joints and high-rigidity output structures. HS/HSG support multiple configurations, while HD is a compact hat-type option for selected frame sizes.
Product Highlights
- Hat-type structure with high output rigidity for robot joints and precision automation.
- HSG reference backlash is <=10 arcsec; HD reference backlash is <=20 arcsec in the manual table.
- Ratio options commonly include 50, 80, 100 and 120 depending on series and frame size.
- Suitable for hollow-shaft layouts, servo actuators, rotary joints and automation modules.
