What is Dynamic Balancing?
Dynamic balancing definition: “Dynamic balancing is a way of balancing machines by rotating parts quickly and measuring the imbalance using electronic equipment. The imbalance measured can then be corrected by adding or subtracting weight from the rotating parts until the vibration is reduced.”
Basically, all machines have some form of residual vibration. Enormous vibration in rotating machinery can cause high levels of noise and more importantly, significantly reduce the life of components. So, the ideal thing to do would be to remove all causes of vibration and allow the machine to run completely smooth. The process of balancing is the removal or addition of weight to the device, so that this effective mass centre approaches the true axis.
In addition to dynamic balance, there is also static balance. When a part is statically balanced, the centre of gravity is on the axis of the rotation. This means the part will stay stationary at a horizontal axis, without the application of braking force. It also has no tendency to rotate due to the force of the gravity.

Our dynamic balancing machine and procedures
We provide balancing services to companies in the UK who have rotors, fans, impellers or shafts that need to be balanced dynamically. Our dynamic balancing machine can handle loads of up to 500Kg, up to 3 metres in length and can balance them down down to ISO G1, which is the finest grade of balance. We can balance any item up to a service speed of 100,000 Rpm.
After the job is completed, we will deliver all items back to you, with the addition of a balancing certificate highlighting the initial and residual out of balance readings.

Balancing your parts
The balance service we offer covers everything from fan balancing to shaft balancing and much more. Whether you need individual balancing or bulk balancing, our team of specialists are on hand to help. With a highly proficient dynamic balancing machine, we can be sure to provide a professional and efficient service, each and every time.
We typically carry out fan balancing, shaft balancing and rotor balancing, but we cover a vast range of other parts. If the part rotates then we’ve probably already balanced it.
As one of the UK’s leading providers of dynamic balancing, we are the perfect partner to help balance your parts. Offering a nationwide dynamic balance service (carried out in-house at our balancing facility), there’s no reason why you would look elsewhere to have your parts balanced.
Reasons you might require dynamic balancing
- To remove dirt build-up
- Impeller erosion
- Internal part corrosion
- Casting imperfections, voids and inclusions
- Mismatched lengths of keys and keyways
- Thermal and mechanical distortion
- Shifting mass due to loose parts or poorly tapered hub fits
- Previous balancing attempts have been unsuccessful
- Parts haven’t been assembled properly
- Noise reduction
- Vibration reduction/elimination
- Increased performance
- Extended motor life
