Dynamic Balancing Rigid Rotors


IKAD Engineering is accredited by the National Association of Testing Authorities, Australia (NATA accreditation number 19655) for Dynamic Balancing of Rigid Rotors up to a maximum weight of 3000kgs.


Rotors are either classified as rigid or flexible. A rigid rotor is one whose service speed when in operation is less than 50% of its first critical speed. The critical speed is the theoretical speed at that causes the object to resonate, which dramatically increases system vibration. Above this speed, the rotor is said to be flexible.

IKAD Engineering utilizes a Schenck hard bearing Balancing Machine Model H40 BU with the following capacities;

  • Maximum Rotor Weight: 3000 kgs
  • Maximum Rotor Diameter: 2600mm
  • Rotor Shaft Diameters: 15mm to 240mm
  • Minimum Journal Centre Line: 170mm
  • Maximum Journal Centre Line: 4700mm

Dynamic Balancing is a process by which a rotor is supported on bearings encased in wheels and rotated about its axis at speed generally less than its service (operational) speed.

In doing so any out of balance forces are measured and recorded. The resultant out of balance forces are corrected by the addition or removal of weight, the position and amount of which is determined and indicated by the machine’s in-built computer.

Rotors are essentially rotating parts of machines and typical examples are;

  • Fans
  • Pump Impellers
  • Turbine Rotors
  • Compressor Rotors
  • Turbocharger Rotors
  • Shafts
  • High Speed pulleys and gears
  • Flywheels
  • Discs
  • Armatures
