Angular Misalignment
Angular misalignment produces a bending moment on each shaft, and this generates a strong vibration at 1X and some vibration at 2X in the axial direction at both bearings, and of the opposite phase. There will also be fairly strong radial and/or transverse 1X and 2X levels, but in phase.
Angular Misalignment
Misaligned couplings will usually produce fairly high axial 1X levels at the bearings on the other ends of the shafts as well!
