Description

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.
