From a standpoint of axle design, a detailed statistical information about the fatigue limit of press-fitted axles is required. Little data are, however, available for the design of press-fitted axles. The objective of the present paper is to obtain a basic information on the scatter of fatigue limits of the press-fitted axles for the statistical evaluation of design safety factors, and then to confirm the allowable stresses given in JIS (Japan Industrial Standard) for the axle design. In the present paper, the rotating bending fatigue test was made on the normalized or quenched and tempered medium carbon steel axles. The stair-case method was applied to investigate the statistical properties of fatigue limit of the press-fitted axles. The results show that the standard deviations which are the measure of scatter in the fatigue limit are 0.22 kg/mm^2 for the normalized and 0.63 kg/mm^2 for the quenched and tempered steel axles.
