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

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

Watch our Balancing Know-How: Diagnosing Unbalance video for a quick introduction to diagnosing machinery unbalance with vibration analysis. Pair it with our 2-plane VIBWORKS Field Balancer to identify and correct unwanted consequences of equipment unbalance to achieve an optimal balancing job!
