ANSI/ASA S2.75-2017/Part 1 Shaft Alignment Methodology, Part 1: General Principles, Methods, Practices, and Tolerances
Abstract
In 2010, the Vibration Institute sought to establish a certification for shaft
alignment technicians, similar to their certification for vibration technicians and analysts.
Various alignment tool vendors and industry consultants had published tolerances for acceptable alignment of flexible
couplings, but these varied among sources. Machinery manufacturers published various shaft alignment
guides for their specific machines, but these varied widely in methodology and acceptable tolerances.
Some industry specific standards did exist such as the API standard for machine installation, but these
were not easily applied outside of those specific industries. The Vibration Institute then launched an
effort in conjunction with the Acoustic Society of America, (ASA), to produce a shaft alignment standard
that could be applied broadly across industries, and that would form a basis for the development of a
certification for shaft alignment technicians. The standard presented here is the culmination of that
effort.
