RasuunDrive® UHV 19mm – Type 7
The RasuunDrive® UHV 19mm – type 7 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. A mounted encoder with 10240 pulses per revolution at the second end of the stepper motor enables to drive the system in close loop control. At its core is a zero-backlash MaalonDrive® gear with a reduction ratio of
160:1. 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 lybricated with vacuum grease Krytox XHT-BDZ. The encoder comes along with 1m cabel which is suitable for UHV. And additionally a cable 3m long with a 15 Pins D-SUB connector only for normal pressure. To connect both cables a small PCB is included and each cable is equipped with a JST Micro connector. PCB and JST Micro connectors can be removed for vacuum feedthrough.
Benefits
1) Vacuum suitable lubrication
2) Use of high quality materials
3) Easy controllability
4) Zero backlash at optimised fit between speed and resolution
5) Ball screw
