  • Continuous rotary motion and 8 inch linear travel
  • Manual actuator
  • UHV or HV compatible materials
  • Differentially pumped, Dual Viton® elastomer shaft seal
  • Bakeable to 100ºC
  • Del-Seal™ CF and Kwik-Flange™ port mounts

Differentially pumped direct drive rotary-linear motion feedthroughs are a basic and economical solution for vacuum applications requiring both rotary and linear motion. Their simple construction provides 100 lb-in of manual rotational torque.

The rotary shaft is supported by two phosphor bronze bearings and uses dual Viton® elastomer shaft seals. The region between the seals can be differentially pumped through the 1/8" female pipe thread port provided and thus attain UHV compatibility to 10-9 Torr. Feedthroughs are available on industry standard Conflat® compatible 2-3/4" diameter Del-Seal™ CF metal seal flanges or ISO KF NW40 Kwik-Flange™ port mounts.
