Offset Helical Geared Lean Motors

Stober offset helical servo geared motors are designed for small installation spaces, with a large axial distance, and high positioning accuracy, and are powerful at the same time. 

Due to their extremely flat housing and large axial distance, offset helical gear units are easy to integrate with applications that have very tight, difficult space constraints. These gear units also meet high demands for efficiency, ruggedness, and long service life.
