Overview
The SITO DRIVE CS-20-I reducer is offered in 30, 50, 80, 100, and 120 transmission ratios for the listed robotic applications. At a 2000 r/min input, rated torque ranges from 15 to 47 Nm by ratio; specified backlash is ≤20 arcsec for ratios 30 and 50, and ≤10 arcsec for ratios 80, 100, and 120. Select the ratio to suit the required drive characteristics.
Applications
- Humanoid Robots, Robotic Arms, Exoskeletons, and Quadruped Robots: the available ratio options support selection of reduction characteristics for joint-drive designs.
- AGV Vehicles and ARU Robots: the available ratio options support selection of reduction characteristics for drive designs.
