MaalonDrive® Space 8mm – Type 3
Dry lubrication, extremely small outer dimensions and robust operating behaviour characterise the MaalonDrive® Space 8mm – type 3 micro positioning system, which is designed for use in extreme environmental conditions.
It can easily be actuated in an open loop control, as it is driven by a stepper motor with 20 steps per rotation.
At the core of the drive is a zero-backlash MaalonDrive® gear with a reduction ratio of 160:1.
On the output side, the micro gearbox is equipped with a preloaded ball bearing by means of which the application is optimally mounted.
Benefits
1) High repeatability
2) Suitable in wide temperature range
3) Dry lubrication due to coatings
4) Preloaded ball bearing
5) Zero backlash with optimised fit between speed and resolution
