Inline and Offset Gear Units

STOBER servo inline and offset gear units are available as planetary gear units and as helical or offset helical gear units. Offset helical gear units have a parallel input and output and a large shaft-centre distance. All other gear units are of inline design. All gear units are provided with high-quality helical gearing for unrivalled smoothness of running and backlash stability. Backlash down to ≤1 arcmin. Short motor adapter length. Easy and secure motor mounting. Can be attached to almost any make of servo motor.
