Unbalance occurs when the rotor’s mass is no longer at the center of rotation.  Unbalance can be caused by many factors:

  • Assembly error
  • Machine tolerances
  • Eccentric components
  • Wear
  • Corrosion
  • Thermal distortion
  • Mechanical distortion
  • Material buildup
  • Bent components
  • Broken components

Many things can prevent the successful correction of unbalance.  Equipment resonance, bearing issues, product buildup, and many more equipment problems can prevent a successful balancing job from being completed.  All Equipment defects should be corrected before attempting to balance equipment.
