VBMDS2-40 Dual concentric axis transfer rod DN40CF

High quality UHV magnetically-coupled dual axis transfer rod with linear motion and two independent rotation axes. Standard travels from 300-1000mm in 100mm increments.

Key Features


  • Flange Size: DN40CF with through holes
  • In-vacuum shaft diameter (outer shaft for first rotation): 20mm
  • In-vacuum shaft diameter (inner shaft for second rotation): 6mm with a flat on one side
  • Air side support attachment: M8 threaded hole, 10mm deep
  • Rotation 1 and rotation 2: 0-360º, independent motion
  • Transferrable axial force: 50 N
  • Transferrable torque: 2 Nm (axis1), 1Nm (axis 2)
  • Maximum bakeout temperature: 230ºC (UHV compatible)
  • Pressure range: 1bar- 10-11 mbar
  • Helium leak rate: <1×10-10 mbar l s-1
  • Options available (please ask!):
    • stop ring (Part number VB-MDS-AR)
    • port aligner (Part number VB-JUMEM40#)
    • Transfer tool / sample holder
    •  attachment to remove the rotation axis and change to linear-only motion (Part number VB-MLH)
    • attachment for remote operation, especially useful for longer transfer rods (Part number VB-MDF)
    • X-table to provide an additional vertical or lateral movement (Part number VBX40-12)
    • Stepper motor operation of both axes (increased flange size of DN100CF for this option)
