Overview
The SITO DRIVE HS-17-I reducer is available with 30, 50, 80, or 100 transmission-ratio options for robotic motion applications. At a 2000 r/min input speed, rated torque ranges from 8.8 to 24 Nm by ratio, while backlash is specified from ≤20 to ≤10 arcsec. Compare the ratio-specific torque, allowable load, and backlash values below when selecting an option.
Features
- HS-17-I reducer with four selectable transmission ratios: 30, 50, 80, and 100.
- Maximum allowable input speed of 7300 rpm and allowable average speed of 3500 rpm for every ratio option.
- Ratio-specific torque ratings, load-torque limits, instantaneous torque limits, and backlash specifications.
