Overview
The SITO DRIVE CS-14-I reducer is offered with speed-ratio options of 30, 50, 80, or 100 for robotic motion applications. At a 2000 r/min input, rated torque ranges from 4 to 7.8 Nm by ratio, while allowable backlash is ≤20 arcsec for ratios 30 and 50 and ≤10 arcsec for ratios 80 and 100. Select the ratio to match the required torque and backlash values.
Applications
Use the available ratio options in robotic motion designs where reduction ratio, torque limits, input speed, and backlash must be matched to the application.
- Humanoid robots
- Robotic arms
- Exoskeletons
- Quadruped robots
- AGV vehicles
- ARU robots
