It is well known that misalignment is one of the greatest causes of failure in rotating equipment. In fact, research demonstrates that more than 50% of machine breakdowns are the direct result of poor alignment. But correcting misalignment can be a challenge. Misalignment can have many causes. Alignment is not a static condition. Alignment changes. Effectively countering the factors that influence or alter alignment depends on understanding how the alignment of your machine changes over time and with use.
