MaalonDrive® Hollow 10mm – Type 8
The MaalonDrive® Hollow 10mm – type 8 micro positioning system combines hollow shaft, tool holder and vacuum supply in one system.
The robust bearing of the output shaft and the ability to use a gripper tool directly in the input shaft via a magnetic coupling are the main highlights of this micro actuator solution.
The micro positioning system can easily be operated in an open loop control, as it is driven by a stepper motor with 20 steps per rotation.
At the heart of this precise and reliable micro gearbox is a zero-backlash MaalonDrive® gear with a reduction ratio of 160:1.
Benefits
1) Hollow shaft thru center of rotational axis
2) Preloaded ball bearing
3) Custom designed tool holder
4) Integrated tool fitting
5) Integrated vacuum supply for tool
