MaalonDrive® HighVac 10mm – Type 2
The MaalonDrive® HighVac 10mm – type 2 micro positioning system is suitable for use in high-vacuum environments thanks to the used materials and Braycote as lubricant.
The system is driven by a stepper motor with 20 steps per rotation in an open loop control.
The zero-backlash MaalonDrive® gear with a reduction ratio of 500:1 is directly connected to the motor and is equipped with a preloaded ball bearing on the output side.
Benefits
1) High repeatability
2) Vacuum suitable lubrication
3) Preloaded ball bearing
4) Robust control without feedback system
5) Zero backlash at high resolution
