Dynamic balancing is done by testing the roller into a computer-controlled dynamic balancing system at its normal operating speed. It then determines the location and amount of counterweight needed.

A roller core can become imbalanced in two ways: static and dynamic imbalance. Static imbalance is described as the roller rolling to its heavy side when made to rotate freely. On the other hand, a dynamic imbalance is the generation of a rocking motion or vibration when the roller is rotated to its operating speed.Rubber rollers that are especially heavy, large, or have high operating speeds are typically inspected and corrected for dynamic imbalance.
