Field Balancing Apparatus

The imbalance of a rotating machine part may cause harmful vibrations in the entire machine. A familiar example is unbalanced tyres on a car. In rotating machines such as turbines or pumps, vibrations due to imbalance lead to comfort problems or even damage related to overloading. If this balancing is done not on a particular machine but directly on the machine in operation located on-site, it is known as field balancing. These cause annoying and unpleasant vibrations in the steering. This is why almost all rotating parts are balanced.
