Unbalance is one of the most common causes of premature failure in rotating machinery. This is caused from the uneven distribution of mass around an axis of rotation. If you repair a machine, replaced bearings, or performed other service and still experience noise and vibration, you were most likely experiencing unbalance. If not corrected, damage will happen again.

Reasons for Balancing:
A rotor can have material buildup (dirt or grease on fans) or material loss (erosion on material moving fans), bearing wear that affects the center of rotation (severely worn parts need to be replaced before balancing), shaft distortion due to residual stress relaxation, structural changes, or speed increases. This causes vibration that will result in premature failure of bearings and other machine components. It can also result in cracks and other structural defects that could cause catastrophic failure.
The purpose of dynamic balancing is to reduce centrifugal forces that cause damage or discomfort to people near the vibration.
Why & When Would You Choose Field Balancing?
Our Field Balancing Procedures can correct unbalance on in-service equipment right at your facility. This is done by attaching weights or grinding and drilling away material.
As long as there is access to the rotor, dynamic balancing in the field eliminates the need to remove, transport to a balancing shop and reassemble a machine, which is very labor intensive and costly.
Balancing in the field - in the rotor's existing bearings and mounting structure under normal operating conditions can sometimes have a better end result. Lower vibration amplitudes due to unbalance may be achieved with field balancing due to the structural conditions when the rotor is in place.
