Precision-balanced machines run more smoothly and suffer fewer failures – plus they consume less energy. Precision balancing must be part of your reliability improvement strategy.
A precision-balanced rotor reduces the centrifugal forces on the shafts, bearings, and the supporting structure. Unbalance sucks the life out of rotating machinery, greatly increasing the likelihood of premature failure. In addition, unbalance can result in structural failure, poor product quality, and noise that disturbs workers and neighbors of the plant site.
The course is designed to establish the fundamentals and then cover each of the common balancing techniques.
