From the vacuum-compatible screw to the complete vacuum chamber.
Mechanical Transfer Components
Our mechanical rotary unions use magnetic attraction to transmit rotary motion into a vacuum environment. A shaft with permanent magnets is rotatably mounted in the completely hermetically sealed housing on the vacuum side. On the atmosphere side, there is a rotating handle with permanent magnets with opposite poles. The arrangement of the magnets enables you to achieve optimum force coupling and thus precise transmission of a rotary movement from the atmosphere side into the vacuum.
