CoograDrive® HighVac 8mm – Type 1
The CoograDrive® HighVac 8mm – type 1 is a very compact positioning drive designed for use in high-vacuum environments.
Thanks to the dry lubrication in the bearing and the gear component set, the micro positioning system has an excellent outgassing behaviour.
The system is driven by a stepper motor with 20 steps per rotation in an open loop control.
Directly connected to the motor is a low-backlash CoograDrive® gear with a reduction ratio of 80:1.
Thanks to the preloaded ball bearing for the output shaft of the gear, the customer application can be directly connected.
Benefits
1) Compact build up
2) Dry lubrication due to coatings
3) Custom designed output shaft
4) Custom designed housing
5) Connecting cable assembled
