In order to evaluate the influence of fine particle bombarding (FPB) process on the surface strength of the carburized steel, the FPBed disks were fatigue tested using a ball-on-disk type testing machine under a constant loading, From the test results, there was a good possibility that the FPB process after carburizing will be available for the purpose to increase the fatigue life by the improvement of the abnormal layer. In this paper, in order to discuss the influence of FPB on the lubricating condition from the view point of rolling fatigue strength, the oil film thickness was calculated using a commercial software based on the Reynolds equation according to elast-hydro dynamic (EHL) theory. At the initial fatigue stage, it was estimated that the oil film thickness on the FPBed disks was the thickest in all test disks. While, the EHL pressure on the FPBed disks indicated the highest value. The lubricating condition on the FPBed disk at the initial fatigue stage was not always superior to the others.
