Experimental results of the rolling contact hybrid ceramic/steel contact with refrigerant lubrication and their failure mechanisms due to various induced defects are presented in this paper. Fatigue life performance of ceramic bearing elements in relation to indents and radial cracks and their location, position within the Hertzian contact and geometry are discussed. Rolling contact fatigue test programme is provided. The fatigue life performance of the rolling elements with respect to various artificially induced surface defects is studied and the results are discussed and presented in this paper. Surface profiles of the failed specimens, using various techniques were obtained during this research and are presented.
