MD35LB hollow range

MD35LB hollow range

MD35LB series

CF40, 2.75" OD flange, Hollow MagiDrive series

MD35LB is a medium/high-torque, medium-stiffness rotary feedthrough. The MD35LB is provided with calibrated thimble, brake and timing pulley as standard. An adjustable rear flange enables rotation of position prior to fixing. The large 27mm clear bore allows a component to pass through the centre, such as a heater module, a feedthrough or a cold lance.

Key features

  • 27mm clear bore 
  • Magnetically-coupled fail-safe design rotary feedthrough
  • Medium/high torque
  • No bellows or dynamic seals
  • Bakeable to 250°C
  • Zero backlash under low load
  • True UHV performance

High Precision Motorisation Option with <0.02 degrees angular precision

Using the Hypoid Drive on our MultiCentre multi-axis precision stages the angular precision achieved is typically <0.02 degrees.
 This is an important figure of merit as users of MultiCentre manipulators may be performing various angle resolved experiments such as X-ray Photo-electron Diffraction (XPD) where such precision is key.
