Heavy Duty, Micrometer

  • 2 inch linear travel
  • Manual, precision micrometer actuator
  • UHV compatible materials
  • Welded bellows seal
  • Bakeable to 100ºC
  • Del-Seal™ CF port mount

Heavy duty, micrometer driven linear motion feedthroughs allow linear displacement of heavier samples and components with the accuracy and precision of fine pitch thread micrometers. These devices provide position indication on both rotary and linear scales with display resolutions of 0.0001" on the rotary scale and 0.025" on the linear scale. A full revolution of the rotary scale translates into 0.025" of linear travel. Unlike conventional motion feedthroughs, heavy duty models employ reentrant welded bellows construction allowing the use of sturdier and larger diameter shafts. Models with two inch maximum travel are offered on 2-3/4" Conflat® compatible Del-Seal™ CF metal seal flanges.
