MaalonDrive® UHV 19mm – Type 1
Thanks to the dry lubrication and the materials that are used, the compact MaalonDrive® UHV 19mm – type 1 is especially well suited for applications in extreme environmental conditions.
In particular, applications in ultra-high-vacuum environments pose no problem for the positioning unit. It is driven by a stepper motor with 200 steps per rotation, which allows the system to be operated in a simple, open loop control.
The zero-backlash and high-reduction 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 to which the application can be directly connected.
Benefits
1) High repeatability
2) Vacuum suitable lubrication
3) Preloaded ball bearing
4) Robust control without feedback system
5) Zero backlash at high resolution
