The new standards in shaft alignment and machinery installation are a must-have for anyone involved in rotating machinery.
Without a doubt the most important aspect for rotating machinery is the installation or re-installation of the machine. There are other factors, such as operational procedure and design faults – even incorrect lubrication – however, the main factor is the installation. This is the critical element that dictates the life expectancy of the machine. The famous study of Nowlan and Heap tells us that only 11% of rotating machines run to their full life expectancy. Even if you disputed this study, consider the billion-dollar Industrial Supply Industry that supply’s us with chains, sprockets, belts, sheaves, pumps, motors, gearboxes and so on. If we say that the study is correct then we have to admit that we do not do a good job as installers and maintainers of rotating machines.
