Linear Displacement Mechanism


  • For Y-shift adjustment or alignment of specimen transfer tools
  • Compatible with ultrahigh vacuum
  • Provides small movement normal (90°) to the axis of a transfer system mainly to correct transporter droop
  • Mounting flange is either a metric tapped 4-1/2" or 6" O.D. CF (also tapped at half-pitch, allowing for "inline" [European] or "straddle" [U.S.] orientation)
  • Support cantilevered loads
  • Work in any orientation—provides horizontal movement if mounted horizontally, diagonal if mounted diagonally, etc.
  • Can provide the extra axis of freedom required for sample hand-off when combined with any standard rack-and-pinion or magnetically coupled transfer arm
  • Can align any flange-mounted instrument
  • Handwheel, optional DC motor, or stepper motor actuation
  • Travel range: ±5mm
  • Bakeable to 250°C (with motor removed)
  • Precision-ground stainless steel guide system
