VBKPM12 Series XYZ Manipulators

The KPM12 series is a simple, compact, budget-friendly single bellows XYZ manipulator available as standard with a DN40CF flange size at both ends (DN50CF or DN63CF base flange by request). With a 39mm inner diameter of the bellows, to obtain the full +/-12.5mm XY travel, the sample stage support rod and any associated wiring must be 14mm 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 50-600mm. The manipulator has a maximum 10kg load on the z axis.

Key Features


  • Z travel from 50-600mm in 50mm increments
  • X/Y travel +/-12.5mm vector sum
  • Micrometer scales on all axes for repeatable positioning
  • Resolution: 0.01mm manual, 0.001mm motorised
  • DN40CF base flange with through holes, double-drilled for compatibility with straddled or in-line bolt hole orientations
  • DN40CF top flange with threaded holes
  • Bellows inner diameter 39mm
  • 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
  • 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):
    • Top flange with through holes instead of threaded (TD at end of part number)
    • Handwheel to the rear instead of the top for manually operated versions (G at end of part number)
    • DN50CF / DN63CF base flange (bellows size unchanged)
    • Z axis motorisation with 2 phase stepper motor PKP268MD28B (Oriental) NEMA 23 / 2 Nm
    • X/Y axis motorisation with 2 phase stepper motor PKP244MD15B (Oriental) NEMA17 / 0.4 Nm
    • Linear encoder, motor encoder
    • Limit switches to provide feedback if an axis reaches either end of its travel
