Rotary motion feedthroughs impart motion via an all-metal bellows seal. The shaft is supported on MoS₂-coated ball bearings. They can be used used to define a polar axis for a sample or probe. They provide 360° continuous rotation and are mounted on top of XYZ Manipulators or translators to provide rotational axis freedom. They are also used separately where precision angular orientation is needed.

               Rotary motion feedthroughs are available with customshaft lengths and ends for your specific application. Probe extensions are also available. All are available with optional stepper or DC-servo motor drive.

Other styles, sizes and configurations available.
