--- title: Galaxie® GS url: "https://www.wittenstein-group.com/en-us/product/galaxie-gs" date: 2026-02-12 modified: 2026-02-24 lastUpdated: 2026-04-13 --- # Galaxie® GS Galaxie® GS gearbox The Galaxie® GS gearbox combines a compact design with exceptional design freedom. The integrated, particularly large hollow shaft enables cables, media or shafts to be fed through easily, creating ideal conditions for complex system integration. At the same time, the innovative kinematics with flat power transmission ensure high torque capacity, maximum rigidity and permanent zero backlash. The Galaxie® GS is therefore predestined for applications where space saving, technical flexibility and maximum precision are crucial – for example in robotics, medical technology or mechanical engineering.
