MeTraVaC® rotary feedthroughs

The mechanical rotary feedthroughs of the MeTraVaC® series enable the transmission of movements in vacuum systems by means of magnetic force coupling.  Due to the principle, there is no need for dynamic seals, bellows or fluids for force coupling. Due to the one-piece basic housing, the rotary feedthroughs offer leakage-free UHV operation. Shielding of the atmospheric-side rotary handle provides the conditions for use in magnetically sensitive environments. The stainless steel vacuum-side shaft rotates in the dry-lubricated ball bearings, ensuring a bakeout temperature up to 250°C.
