Horizontal 1 to 4 plane Balancing Machine

Flexible rotors can be balanced efficiently.

  • Balancing plane : 1 and 2 (up to 4 -optional)
  • Workpiece Mass : 30kg max.
  • Rotor dia.: ø250mm max.
  • Belt drive dia.: ø20 to 120mm
  • Journal dia. : ø15 to 70mm
  • Span across Bearings :150 to 1,000mm
  • Belt drive system :Upward-Tangential
  • Min. Achievable Unbalance :0.1 µm

High speed spindles, Turbo blowers, Cross flow fan, Drive shafts etc.


  • Realize balancing of flexible rotors by "Multi-speed Multi-plane Balancing Algorithm"
  • Flexible rotor which is very difficult to balance can be easily balanced by multi-speed multi-plane balancing algorithm.
    Before high speed field balancing of assembly, each rotating components should be balanced by this balancing machine, then peaks of resonances can be suppressed.

  • 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
