WebMar 22, 2015 · This edge loading resulted in basically half the bearing taking the load causing high babbitt temperature and high peak film pressure. Babbitt fatigue is caused by dynamic loads on the babbitt surface. Typically in bearings of this type the dynamic loads are caused by vibration and result in peak film pressure fluctuations.

WebApr 1, 2024 · Some bearing steel balls show a local bulge or oval shape, but the surface of the steel ball after peeling is bright and complete. When the size of the steel ball is small or the fracture extrusion and wear are serious, the rolling direction of the material cannot be determined, and it is difficult to carry out conventional fracture analysis.
Web7. Bearing Fits 7.1 Interference For rolling bearings the bearing rings are fixed on the shaft or in the housing so that slip or movement does not occur between the mated surface during operation or under load.
