Overview
The SITO DRIVE CS-25-II reducer is offered in five speed-ratio options: 30, 50, 80, 100, and 120. Rated torque at a 2000 r/min input ranges from 27 to 78 Nm by selected ratio, while backlash is ≤20 arcsec for ratios 30 and 50 and ≤10 arcsec for ratios 80, 100, and 120. It is listed for robotics-related application scenarios.
Applications
- Humanoid robots
- Robotic arms
- Exoskeletons
- Quadruped robots
- AGV vehicles
- ARU robots
