RasuunDrive® HighVac 10mm – Type 8
Designed for use in high-vacuum environments, the RasuunDrive® HighVac 10mm – type 8 micro linear actuator system offers a travel range of 6 mm and is driven by a stepper motor with 20 steps per rotation.
At its heart is a zero-backlash MaalonDrive® gear with a reduction ratio of 500:1 by means of which the spring-loaded, zero-backlash spindle nut system with a pitch of 0.4 mm is driven.
In an open loop control, a resolution in the nanometre range can thereby be realised.
The micro linear actuator system is attached by means of an M6x0.5 thread.
Benefits
1) Vacuum suitable lubrication
2) Robust control without feedback system
3) Integrated limit switches
4) Adapter with thread
5) Zero backlash at high resolution
