A Practical Guide to Shaft Alignment

advertisement 

The goal of this handbook is to provide basic information and guidelines for implementing proper shaft alignment in standard rotating machine systems. Laser alignment is a critical component of a viable rotating machine maintenance strategy. Each strategy can help to reduce unexpected machine failure on its own, but when combined, they form the hub of a proactive maintenance strategy that can not only identify impending problems but also significantly extend machine operating life.
