Overview
The SITO DRIVE HD mini-05 reducer is offered in 30, 50, and 80 transmission-ratio options for robotic systems including humanoid robots, robotic arms, exoskeletons, quadruped robots, AGV vehicles, and ARU robots. At 2,000 r/min input, rated torque varies by ratio from 0.23 to 0.5 Nm; all options specify up to 10,000 rpm input speed and ≤20 arcsec backlash.
Features
- HD mini-05 reducer with selectable transmission ratios of 30, 50, or 80.
- Maximum allowable input speed of 10,000 rpm and allowable average speed of 6,500 rpm for every ratio option.
- Specified backlash of ≤20 arcsec for every ratio option.
