Linear Positioners, moving stages in high vacuum environment

[Fedders]

Hello fellow engineers.

I'm looking for a little direction as to the terminology and/or suppliers of some parts I need to build a Langmuir Probe. I'm unsure as to what some of these parts are called. They are all controlled by a stepping motor.

Attached is a picture of the device I'm trying to engineer. Any direction or suggestions would be greatly appreciated.
