Alignment Application Notes
Alignment Application Notes
To achieve ideal machine alignment, the shaft centerline of one machine
element (such as a motor) must coincide with the centerline extension of
another machine shaft (such as a pump) during operation. In more complex
applications, three or more elements may be aligned in a train.
Misalignment can occur both horizontally and vertically. Most misaligned
machines have a combination of offset and angular misalignment (see fol-
lowing figure).
