"WebOct 21, 2009 · 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. " - Bearing misalignment
