Planetary Gears GSD

Planetary gear GSD, 1- & 2-stage

Its short design makes the GSD line the ideal high-end gearbox for space restricted applications. The output flange for robotics produces highest torsional rigidity. The low standard backlash of the GSD line makes it the perfect fit for highly dynamic applications where highest positioning and speed accuracy is required. The GSD line is equipped with maximum preloaded deep groove ball bearings by standard – optionally, it is also available with taper roller bearings to accommodate higher radial and axial forces.
