What is Balance Adjustment?

Balancing adjustment is the process of aligning a rotating part's center of gravity with its axis of rotation. This process aims to minimize the centrifugal forces and vibrations that originate from unbalances in a part's mass distribution, which can lead to serious problems at high speeds. If a part isn't perfectly balanced, it places excessive stress on bearings and machine components during rotation, which can cause noise, energy loss, premature bearing wear, and even machine failure.

A proper balancing adjustment not only ensures the part runs more stably and quietly but also significantly increases the machine's overall lifespan and efficiency. The balancing process is performed by determining the amount and location of the unbalance in a part, then adding or removing weight at the appropriate points. This process is vital for critical components that operate at high speeds, such as fans, turbines, and motor rotors. At MBS Balance, we provide advanced balancing solutions to ensure that every rotating part is adjusted with the highest precision.

The goal of balancing is not an absolute balance but a measurable and documentable tolerance level. Making the part's center of mass coincide with the axis of rotation means, in practice, reducing the residual unbalance below the permissible value corresponding to the G quality grade defined by ISO 21940-11. For this reason, the statement that a part has been balanced carries meaning only together with a target tolerance and a numerical result showing that this tolerance has been reached.

Balancing is done as static (single-plane) or dynamic (two or more planes) according to the part's geometry; in each case, the amount and angle of the unbalance are measured first, then weight is added to or removed from the appropriate plane. A correctly performed balancing extends machine life by reducing bearing load, noise, and energy loss. MBS Balance manages all steps from measurement to correction in compliance with standards, providing repeatable balancing quality.
