Differentially Pumped Rotary Feedthroughs

Differentially pumped rotary feedthrough providing 360 degrees continuous rotation.

The Differentially Pumped Rotary Feedthrough provides 360° of continuous rotary freedom through the vacuum wall of a UHV system. The feedthrough has two stages of differential pumping isolated by graphite-impregnated, expanded viton seals on special sealing surfaces. A pre-loaded ball bearing set accurately controls the rotating stage position.

Application
The Differentially Pumped Rotary Feedthrough can be combined with manipulators and any other precision positioning devices.

Additional information
The feedthroughs are available with worm drive fine adjust option, providing fine angle adjustment. They are also available with an anti-backlash stepper motor.
