Heavy Duty

  • 2 to 6 inch linear travel
  • Manual actuator
  • UHV compatible materials
  • Welded bellows seal
  • Bakeable to 100ºC
  • Del-Seal™ CF port mounts

Heavy duty linear motion feedthroughs allow linear displacement of larger in-vacuum samples and components. This feedthrough has basic, rotary manual actuation and does not provide position indication. Position must be determined by visual inspection of the in-vacuum sample or component. A heavy duty acme thread lead screw provides 1" of linear travel for every six revolutions of the actuator knob. Unlike conventional motion feedthroughs, heavy duty models have a reentrant welded bellows configuration.

All feedthroughs are constructed using high grade vacuum compatible materials. Feedthroughs are available on industry standard Conflat® compatible Del-Seal™ CF metal seal flanges.
