Product Details

•The RHS-IV series flexspline features a hollow-flanged standard cylindrical design, with an integrated wave generator serving as the solid input shaft; it includes a built-in direct-support bearing and boasts a fully sealed, easy-to-install structure—making it ideal for applications where a synchronous belt or bevel gear drive is mounted directly at the input end. 
• 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 RHS-IV Series    
• Large-caliber hollow-core, flat-shaped design 
• Compact and concise design 
• High Torque Capacity 
• High rigidity 
• Zero backlash 
• Excellent positioning and rotation accuracy 
• Coaxial Input and Output
