Rotary-Linear, Precision

  • Continuous rotary motion and 1/2 inch linear travel
  • Manual or Motorized actuator
  • Rotary position lock
  • UHV compatible materials
  • Welded bellows seal
  • Bakeable to 230ºC
  • Del-Sealº CF port mount

Precision rotary-linear motion feedthroughs are low backlash instruments with a rotary display resolution of 0.1" and a linear display resolution of 0.001". Full revolution of the linear drive translates into 0.025" of linear travel with a maximum overall linear travel of 0.500".Welded stainless steel bellows, a unique off-axis wobble design and the use of rotary shaft bearing supports provide long life and smooth operation. Feedthroughs are available on 2-3/4" diameter Conflat® compatible Del-Seal™ CF metal seal flanges. Motorization options are available for both linear and rotary drive components. If motorization is required on both drives, add each option number to the end of the base part number. Note that the entire linear drive mechanism (manual or motorized) will rotate when the rotary drive is actuated. This must be considered when allocating space for its installation. Motor controls are not included with the motorization options and must be purchased separately.
