# Miniaturized Galaxie®

Miniaturized Galaxie® gearbox

The miniaturized Galaxie® gearbox combines maximum precision with a compact design. The innovative kinematics result in almost complete surface contact during power transmission – for maximum torque density and rigidity. The large hollow shaft offers design freedom, while the permanent zero backlash and high overload capacity ensure reliable performance. Ideal for machine and robotics applications where compactness and maximum accuracy are required.
