# Galaxie® D
Galaxie® D actuator
The Galaxie® combines the revolutionary zero-backlash kinematics with an integrated synchronous motor to create a space-saving actuator. The large hollow shaft enables direct media and cable feedthroughs and reduces interfaces and installation work. For applications that demand the highest precision, efficiency and maximum design freedom.
