Misalignment | Power-MI

Misalignment occurs when there is little accuracy in the alignment between pairs of components, such as coupling elements, bearings, shafts and pulleys. Misalignment usually manifests with strong vibration in the axial and radial directions. Axial readings can present the first harmonics of the rotating speed, 1x, 2x and 3x RPM.
