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. The feedthroughs are equipped with worm drive providing fine angle adjustment. They are available with an anti-backlash stepper motor.
Different motors or motor control systems available (stepper motors, servomotors, IcePAP).
