Horizontal 1 to 4 plane Balancing Machine

Mass of workpiece is up to 1kg. Suitable for high efficiency balancing of rotors with journals.

  • Balancing plane : 1 and 2 (up to 4 -optional)
  • Workpiece Mass : 1kg max.
  • Rotor dia.: ø100mm max.
  • Belt drive dia.: ø10 to 50mm
  • Journal dia. : ø4 to 25mm
  • Span across Bearings :30 to 200mm
  • Belt drive system :Upward-Tangential
  • Min. Achievable Unbalance :0.1 µm

Small spindle rotors, Motor armatures, Turbine rotors, Fans, Rolls, etc.


  • Realize balancing of flexible rotors by "Multi-speed Multi-plane Balancing Algorithm"
  • Vibration at all rotational speed range can be defused by unique "Multi-speed Multi-plane Balancing Algorithm".

  • Selectable for rotor supports
  • Roller bearing and/or V block bearing

  • Selectable for driving system
  • Upward-Tangential, Downward-Tangential, Underslung

  • Expand measuring planes to 4 planes
  • Conventional balancing planes is up to 2 planes.
    However, in case performing 2-plane balancing of rotary part of high speed rotary machine, check structure and shape of rotary part and select proper No. of Correction plane. Otherwise, it may cause higher order vibration of flexural mode under high speed rotation.
    Sigma’s horizontal balancing machine expands No. of Correction plane until 4 planes at maximum, selecting proper No. of Correction plane freely. So the above mentioned problem can be solved easily.

  • Touch screen operation
  • Small foot print
