Shaft Alignment Level 1

This 3 day course provides the basic information and guidelines to implement quality shaft alignment for standard rotating machine systems.

Laser alignment is an essential component of a viable maintenance strategy for rotating machines. In isolation each strategy can help to reduce unexpected machine failure, but taken together they form the hub of a proactive maintenance strategy that will not only identify incipient problems but allows extending machine operating life considerably.

Each section covers one or two examples of the available methods for measuring the required parameters, although many of these methods are available.
