The authors carried out an experimental investigation on the fatigue failure of engine bearings by means of a combination of a slider and bearing metal on a reciprocating bed. Cracks were generated under the condition of mixed lubrication in the vicinity of the contact areas at the stroke ends of the reciprocating bed, where the friction force abruptly increased and reversed its direction. A unique relation similar to the usual fatigue curve was obtained by plotting the friction force against the cycles to failure in place of normal load. The conclusion was further confirmed by an experiment using another testing machine generating an alternating tangent force without sliding.
