Magnetically-Coupled Drive Rotary Feedthroughs
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.
