Shaft alignment is a technical skill that is not common in the construction and maintenance professions, but categorized more like a specialty. It requires unique and expensive measurement instruments, some calculation capability, and relies heavily on experience for successful results on heavy, high-speed, or high-temperature machines. At present there are no universally accepted standards that define good results. The U.S. Navy has some alignment specifications, as do some industrial companies. Unfortunately, the various specifications do not appear similar, nor even cover the same subject matter.
