The effects of lubricating oil additives on the pitting life of a radial needle bearing and a thrust needle bearing used for a transmission in passenger cars were investigated. Lubricating oil additives formed a tribofilm with tens of nanometers on the rolling surface of the needle bearing, and the difference in the pitting life of the radial needle bearing was about twice and that of the thrust needle bearing was about 30 times according to a lubricating oil additive. The pitting life was related to the hardness of the tribofilm; i.e., the pitting life grew longer as the tribofilm became softer.
