What is balancing, what are the types of balancing machines, and how is balancing done? Everything you need for vibration-free, efficient and long-lasting rotating equipment — in one guide.
Balancing is the process of correcting uneven mass distribution in a rotating part so that its center of mass aligns with its axis of rotation.
Every part that rotates at high speed — fans, turbines, rotors, shafts, turbochargers — generates centrifugal force and vibration when it carries mass imbalance. This vibration leads to premature bearing wear, noise, energy loss and, in severe cases, machine failure. Proper balancing solves these problems at the source.
Through balancing, your machine runs more quietly and stably, energy efficiency improves, and equipment life is significantly extended. That is why balancing is an indispensable engineering discipline in modern industrial production.

View →For testing the flow performance of turbo and engine parts. Enable optimization through precise measurement.
View →Balancing consists of two essential phases: measurement and correction. Here are the core steps of precise balancing.
The part is cleaned and securely mounted on the machine with suitable adapters. Correct mounting that reflects real operating conditions is the key to accurate measurement.
The part is rotated; precise sensors detect vibration. The software calculates the amount (grams) and angular position of the imbalance and displays it.
Based on the data, weight is added (welding, bolts) or material is removed (drilling, milling) opposite the imbalance, aligning the center of mass with the axis of rotation.
The part is re-tested. The cycle repeats until residual imbalance falls within the tolerance accepted by standards such as ISO 21940.
Advanced software such as MBS Balance's iBalancer digitalizes this process, making it faster, more precise and more intuitive while minimizing operator error.
Discover the iBalancer software →Every rotating part needs balancing. That is why balancing machines are used across a very wide industrial spectrum.
From automatic solutions that keep pace with mass production lines to flexible machines for custom projects, balancing is available for every sector.
See the full product range →ISO 21940 is the international standard defining the mechanical vibration and balancing quality of rotating rigid rotors. Balancing continues until the part falls within the tolerance classes defined by this standard, ensuring equipment safety, performance and lifespan according to internationally accepted criteria.
