Servobox SR 2-Stage High-Precision Planetary Gearbox

The Servobox SR 2-Stage extends the SR platform with a second planetary stage for higher reductions from 10 to 90. It maintains IP65 sealing, 3000 rpm rated input (6000 rpm max), and synthetic grease lubrication. Efficiency is specified at ≥94% with backlash ≤8 arcmin, offering higher reduction capability with compact industrial construction.
