Imbalances on rotating machines are often the cause of disruptive vibrations and noise. During imbalance, the principal axis of inertia or centre of gravity of the rotating machine component is outside its axis of rotation. By adding or removing masses, the centre of gravity or the principal axis of inertia can be shifted so that both coincide with the axis of rotation. This process is called balancing. The machine component is then balanced and runs without vibration.
