Vibration Due To Shaft Misalignment

2009-10-21  The more severe the misalignment, the closer the phase differences will be to 180 degrees. 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.
