RasuunDrive® UHV 19mm – Type 3
The RasuunDrive® UHV 19mm – type 3 is using Braycote 601 EF for lubrication as it is espacially designed for applications in ultrahigh-vacuum environments. It offers a travel range of 25.5 mm and
is driven by a stepper motor with 200 steps per rotation in an open loop control. Directly connected to the motor is a low-backlash CoograDrive® gear with a reduction ratio of 40:1 by means of
which a dry-lubricated ball-screw drive with a pitch of 0.5 mm is driven.
Benefits
1) Vacuum suitable lubrication
2) Use of high quality materials
3) High axial load capacity
4) Robust control without feedback system
5) Adapter with cylindrical surface
