Overview
The SITO DRIVE CS Mini-11 reducer is offered in 30, 50, and 100 speed-ratio options for robotic transmission applications. At a 2000 r/min input, rated torque is 2.2 Nm, 3.5 Nm, or 5 Nm respectively. Each option lists an 8500 rpm maximum allowable input speed, 3500 rpm allowable average speed, and ≤20 arcsec backlash.
