MaalonDrive® Space 8mm – Type 2
The input shaft of the MaalonDrive® Space 8mm – type 2 micro positioning system is designed space-optimised as a worm for the subsequent worm gear.
Thanks to the dry lubrication and the materials that are used, the compact MaalonDrive® Space 10mm – type 1 is especially well suited for applications in extreme environmental conditions.
The micro positioning system can easily be actuated in an open loop control, as it is driven by a stepper motor with 20 steps per rotation.
On the output side, the system is equipped with a preloaded ball bearing by means of which the worm is optimally mounted.
Benefits
1) High repeatability
2) Dry lubrication due to coatings
3) Preloaded ball bearing
4) Zero backlash with optimised fit between speed and resolution
5) Worm gear integrated on output shaft with custom designed worm wheel
