Section 6, Axial Vibration Symptoms Due to Shaft/Coupling Misalignment. ... Some use the rule that when the axial vibration reaches at least 50 percent of the radial vibration (horizontal or vertical), the source for the vibration is coupling misalignment. This rule is a reasonably good one but, unfortunately, is not always reliable. ...
