PP & XPP Range

PP & XPP Range

Linear & rotary magnetically-coupled transfer arm


High-performance magnetically-coupled combined linear/rotary devices, designed for sample transfer. Both linear and rotary motion of the sample achieved via a single actuator with stroke length from 304mm to 1524mm.

The PowerProbe provides both linear and rotary motion of the sample, via a single actuator. 

For demanding UHV applications,  we recommend choosing the XPP option with rolling metal & ceramic bearings for smooth low friction actuation with minimal outgassing.  Click here to learn more about our XPP option.



Key Features

  • Linear and continous rotary motion
  • Unrivalled 140N axial coupling strength with 4Nm torque
  • Bakeable to 2500C without having to remove the outer magnets
  • Exceptional axial stiffness 
  • Zero backlash under low load
