Overview

The SITO DRIVE HS-25-I reducer is offered in 30, 50, 80, 100, and 120 speed-ratio options for robotic motion systems. At a 2000 rpm input, rated torque ranges from 27 to 67 Nm by ratio, while maximum allowable input speed is 5600 rpm. Select the ratio according to the required torque, backlash, and motion arrangement.

Features

Five selectable speed ratios: 30, 50, 80, 100, and 120.
Maximum allowable input speed of 5600 rpm and allowable average speed of 3500 rpm for every listed ratio.
Backlash of ≤20 arcsec for ratios 30 and 50, and ≤10 arcsec for ratios 80, 100, and 120.
