Thermionics FRM series rotary feedthrough is metal-sealed and are all metal, using welded bellows and stainless steel bearings. All manual units are bakeable to 200°C fully assembled. Higher bakeouts may be used with partial disassembly. These feedthroughs are also available with a number of custom options.
Precision rotary feedthroughs are commonly used to define a polar axis for a sample or probe where precision angular orientation is needed. They provide 360° continuous rotation and are mounted on top of XYZ manipulators and other stages to provide polar axis freedom. Available with custom probe lengths and field-mountable probe extensions for your specific application.
The rare earth magnetic series single and dual rotary drives are designed as an option to conventional bellows-sealed and other rotary devices. They can be adapted to PLD target clocking and continuous rotation of targets and substrates, as well as applications which require small profiles and high performance. There are no sliding seals or magnets in vacuum and stray magnetic fields are virtually nonexistent. The in-vacuum armature is made of paramagnetic materials with stainless steel and silicon nitride bearings and is capable of repeated bake-out to 200°C (with magnets removed). Out-of-vacuum bearings are accessible for lubrication and the magnet drive is easily removable.
The WOA rotary feedthrough is an all metal-sealed rotary feedthrough with the unique feature of a 3/4″ rotary tube with a clear axis diameter of 0.55″. This open axis feature allows a multi-axis feedthrough to be constructed by stacking multiple linear or rotary feedthroughs onto the WOA feedthrough. A variety of coaxial rotary and/or linear drives can be produced. m.
