Product Details

•The RCSG-II series combined flexspline features a cup-shaped standard cylindrical structure, with the input and output shafts aligned on the same axis. The input shaft is connected via an interference fit inside the bore of the cross-axis wave generator.
• The high-torque model offers a 30% higher torque capacity compared to the standard series, with a 40% extended service life.
• Lightweight housing design—30% lighter than all-steel models, offering faster heat dissipation and reduced vibration.

Features of the RCSG-II Series
• Compact and concise design
• High Torque Capacity
• High rigidity
• Zero backlash
• Excellent positioning and rotational accuracy
• Coaxial Input and Output
