Overview
The SITO DRIVE CS-17-II reducer is offered in 30, 50, 80, and 100 transmission-ratio options for the listed robotic application scenarios. At a 2000 r/min input, rated torque ranges from 8.8 to 24 Nm by ratio, while maximum allowable input speed is 7300 rpm and allowable average speed is 3500 rpm. Ratio-specific torque and backlash values are provided below for configuration selection.
Features
- Four transmission-ratio options: 30, 50, 80, and 100.
- Maximum allowable input speed of 7300 rpm and allowable average speed of 3500 rpm for every listed ratio.
- Backlash of ≤20 arcsec for ratios 30 and 50, or ≤10 arcsec for ratios 80 and 100.
