MaalonDrive® HighVac 8mm – Type 1
The MaalonDrive® HighVac 8mm – type 1 micro positioning system was designed for use in high-vacuum environments, is lubricated with Fomblin and is characterised, in particular, by its compact design and high positioning resolution.
The combination of a zero-backlash MaalonDrive® gear with a reduction ratio of 160:1 with an EC motor with rated voltage of 6V results in a precise, high-performance micro drive system.
The gear is equipped with a preloaded ball bearing and an output shaft with application-specific design.
Benefits
1) High repeatability
2) Vacuum suitable lubrication
3) Preloaded ball bearing
4) Easy controllability
5) Zero backlash with optimised fit between speed and resolution
