BeamTec has extended its product range of rotary vacuum feedthrough with magnetical sealing technology. The hermetical seal is achieved using o-rings made of a magnetic fluid around the rotating shaft. Specially shaped shafts and housings in combination with strong magnets ensure that the ferrofluid forms a smooth and flexible yet vacuum-tight barrier.

Benefits of this tehnology include long maintenance intervals, operation reliability and high rotation speed and tranfer of high torque forces.
The feedthroughs can be cooled using water or helium.

We provide a wide selection of different models or the possibilty to design and manufacture custom feedthroughs according to your specifications.

Typical applications are any kind motion transfer that require rotational movement in vacuum systems such as substrate holders, transport rolls or swivel blinds.

A selection of feedthroughs can be found in our Onlineshop.
