EZ Inline and Offset Geared Motors

STOBER servo inline geared motors are available as planetary geared motors and as helical or offset helical geared motors. Offset helical geared motors have a parallel input and output and a large shaft-centre distance. All other geared motors are of coaxial design. All drive units are provided with high-quality helical gearing for unrivalled smoothness of running and backlash stability. Backlash down to ≤1 arcmin. Super compact synchronous servo motor EZ for high dynamic.
