One Axis Manipulators

High Stability Linear Shift

Description

The High Stability Linear Shift is a UHV transfer mechanism that is fabricated from a pair of flanges, connected by an edge welded bellows. The free flange moves towards the fixed flange in a controlled, precise motion whilst maintaining parallelism. It incorporates a linear guide shaft that moves on linear bearings. Its action is similar to the Z Slide manipulator, but with slightly reduced travel length and overall positioning resolution. The standard mounting flange is DN 40CF or DN 63CF. The shift is actuated by a handwheel and can work in any orientation.

Application

The High Stability Linear Shifts are used in applications that don’t require the higher precision and graduated movement of other linear motion devices. They are normally used for:

  • Manipulation of surface science tools with respect to the sample position
  • Manipulation of evaporation and sputter sources
  • 
Manipulation of electron and X-ray sources
  • Manipulation of quartz oscillators
  • Sample transfer applications

Additional information

The High Stability Linear Shifts are designed for the linear movement of instruments with minimum tilt or wobble in the movement, maintaining precision alignment before and after pump-down
