Vibration Due To Shaft Misalignment

Oct 21, 2009· When the vibration is at a frequency equal to shaft speed (1×), phase is the best tool for distinguishing between misalignment and unbalance. Take several phase readings at each point to ensure accurate phase data that may vary due to speed changes. When axial vibration at 1× or 2× is 50 percent or more of radial vibration, suspect misalignment.
