Low backlash high precision gearboxes from MeliorMotion® GmbH

Components / Sub-assemblies

Series PSC- V/H - E

MeliorMotion® offers high precision gearbox components/sub assemblies. 

These gearboxes have backlash of ≤ 0.1 arcmin are considered backlash-free. 

With patented solution for wear regulation, it is to ensure that backlash does not change over the entire service life.

More safety for your application is offered by low-backlash gearboxes thanks to high output, acceleration and emergency stop moments.

MeliorMotion® gearbox series has exceptionally high tilting and torsional stiffness. These ensure precise positioning straight-to-the-point.
