Overview
The SITO DRIVE CS-14-II reducer is offered with 30, 50, 80, or 100 transmission-ratio options for robotic applications including humanoid robots, robotic arms, exoskeletons, quadruped robots, AGV vehicles, and ARU robots. At a 2000 r/min input, rated torque ranges from 4 to 7.8 Nm by selected ratio. Compare the ratio-specific torque limits, backlash, and speed ratings below when selecting a configuration.
Features
- CS-14-II reducer with four selectable transmission ratios: 30, 50, 80, and 100.
- Maximum allowable input speed of 8500 rpm and allowable average speed of 3500 rpm for every listed ratio.
- Backlash is rated at ≤20 arcsec for 30 and 50 ratios, and ≤10 arcsec for 80 and 100 ratios.
