Section 5, Misalignment Vibration at 1 x rpm of Rotor. The most common major vibration amplitude due to misalignment is at a frequency of 1 x rpm. It sometimes is accompanied, or even exceeded, by vibrations at other frequencies such as at 2 x rpm. But for about 90 percent of misaligned machines, the major vibration symptom is at 1 x rpm.
