Overview

The SITO DRIVE HS-25-IV Reducer is offered in 30, 50, 80, 100, and 120 transmission-ratio options for robotics motion-reduction assemblies. At a 2000 r/min input speed, rated torque ranges from 27 to 67 Nm by ratio. Select the ratio to match the required torque, allowable speed, and backlash specification for the intended mechanism.

Applications

Use the selected transmission ratio and corresponding torque limits when configuring motion-reduction assemblies for humanoid robots, robotic arms, exoskeletons, quadruped robots, AGV vehicles, and ARU robots. The ratio-specific torque and backlash values help match the reducer option to the mechanism’s operating requirements.
