..., the individual corrosion pits acted as stress raisers and initiated coarse grain spalling. Due to a bending moment on the rotating element, this in turn initiated bending fatigue normal to the longitudinal axis, which propagated through to the bore of the inner ring. Stain marks were visible in the bore...

.... This misalignment can cause vibration and ultimately result in a fatigue failure in the shaft [ 1 ]. A gear shaft is usually subject to a high torsional moment and a bending moment as well as cyclic stresses which, when combined, may cause fatigue in the shaft. These factors may be influenced by stress...
