Abstract:

A hybrid ceramic/steel angular contact ball bearing is experimentally modelled using a modified four-ball machine. Ceramic ball surfaces are artificially damaged with ring pre-cracks. Rolling contact fatigue failure modes are studied after testing with high contact stresses and speeds. The ceramic ball surface and subsurface are analysed in detail using electron microscopy and a dye-penetration technique. © 1993.
