VBMAX25 Series XYZ Manipulators

The MAX25 series is a large single bellows XYZ manipulator available as standard with a DN100CF base flange (DN160CF or DN200CF by request), and a DN100CF moving flange (DN63CF by request). Unlike the PM125, the XY table is at the bottom rather than the top for maximum rigidity and a more compact minimum flange to flange distance for the respective travels. With a 102mm inner diameter of the bellows, to obtain the full +/-25mm XY travel, the sample stage support rod and any associated wiring must be 52mm diameter or less. The manipulator can be supplied with all axes manually-operated, motorised Z axis or with all 3 axes motorised. Z travels are available from 50-700mm. The manipulator has a maximum 40kg load on the z axis.

Key Features


  • Z travel from 50-700mm
  • X/Y travel +/-25mm vector sum
  • Bellows inner diameter 102mm
  • Micrometer scales on all axes for repeatable positioning
  • Resolution: 0.01mm manual, 0.001mm motorised
  • DN100CF base flange with threaded holes
  • DN100CF top flange with threaded holes (with through holes for travels >200mm)
  • UHV compatible, bakeout up to 230ºC (motors have to be removed if motorised)
  • Flanges 316LN, tube and bellows 316L stainless steel
  • Pressure range 1 bar – 1×10-11 mbar
  • Maximum load on Z axis 40kg
  • Two positionable mechanical limits for the Z axis to limit the travel within its range
  • Options available (not listed in the table below, please ask):
    • DN63CF top flange
    • DN160CF or DN200CF base flange
    • Base flange with through holes rather than threaded (length A increases by 35mm)
    • Manual handwheel at the top instead of the bottom for handwheel version (O at end of part number, adds 35mm to length B)
    • motorisation of Z axis with 2 phase stepper motor PKP 299 D 45B (Oriental) NEMA 34 / 6 Nm
    • motorisation of XY axes with 2 phase stepper motor PKP268MD28B (Oriental) NEMA 23 / 2 Nm
    • Linear encoder, motor encoder
    • Limit switches to provide feedback if an axis reaches either end of its travel
