# Galaxie® G

Galaxie® G gearbox

The Galaxie® G gearbox represents a new generation of high-precision drive technology. With its unique kinematics and the principle of complete surface contact during power transmission, it achieves exceptional rigidity and torque density. The combination of a large hollow shaft, permanent zero backlash and high overload capacity makes the Galaxie® G the ideal solution for demanding mechanical engineering and robotics applications where maximum performance and design freedom are required.
