RasuunDrive® UHV 19mm – Type 6
The RasuunDrive® UHV 19mm – type 6 was designed as a
linear actuator system for ultra-high-vacuum environments and
offers a travel range of 10 mm. The system is driven by a stepper
motor with 200 steps per rotation in an open loop control. At its
core is a strong CoograDrive® gear with a reduction ratio of
80:1. The stroke is realized by a ball-screw drives with a pitch of 1 mm. The linear actuator system is
attached by means of a 3/8″ – 40 UNS thread; the load is coupled
via a spherical surface. All moving components are dry lybricated or coated with Dicronite.
Benefits
1) Dry lubrication due to coatings
2) Use of high quality materials
3) Simple integration to the application
4) Robust control without feedback system
5) Ball screw
