Product Details

•The RHSG-III series flexspline features a standard hollow-flanged cylindrical design, with a large-diameter hollow shaft bore inside the wave generator. It incorporates a built-in direct-support bearing and boasts a fully sealed, easy-to-install structure—making it ideal for applications where wiring runs directly through the reducer. 
• The high-torque model offers a 30% higher torque capacity compared to the standard series, with a 40% extended service life. 
• Lightweight housing design—compared to all-steel models, it’s lighter, conducts heat more efficiently, and reduces vibration significantly.

Features of the RHSG-III Series  
• Large-caliber hollow-core flat shape 
• Compact and concise design 
• High torque capacity 
• High rigidity 
• Zero backlash 
• Excellent positioning and rotation accuracy 
• Coaxial Input and Output
