Horizontal 1 to 4 plane Balancing Machine

Shaft center axis is fixed by own bearings, high-precision balancing can be performed.

  • Balancing plane : 1 and 2 (up to 4 -optional)
  • Workpiece Mass : 80kg max.
  • Rotor dia.: ø195mm max.
  • Belt drive dia.: ø20 to 125mm
  • Span across Bearings :160 to 720mm
  • Belt drive system :Underslung
  • Min. Achievable Unbalance :depend on rotational speed

Rotor shafts of spindle, Turbine rotors of jet engine, 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
  • Small foot print
