Sliding and rolling bearings are the basic components of machine construction. In machine systems operating at high speeds (>600 RPM) and not frequently performing stop-start movements, the use of sliding bearings is more meaningful both technically and economically. The oil film formed between the shaft and the bearing is of great importance for the efficient operation of sliding bearings. In this study, the increase in bearing performance was investigated by creating pockets on sliding bearing surfaces by shot peening. In the study where tin bronze was used as the sliding bearing material, it was aimed to increase both the fatigue strength of the bearing material and the adhesion surface of the oil by shot peening. Different oil pocket structures were created on the bearing surfaces by using different peening parameters and lubrication performance was tried to be increased by using nanoparticle-added oil as a lubricant. In the experimental study where nanosilver-added oil was used, it was aimed for nanoparticles to act as a tribological performance agent on the lubrication pockets. According to the results, ~125 HV hardness increase was achieved on the material surface and the fatigue life of the material was increased by 7 times. It was determined that the bearing performance increased under the conditions of using low Almen intensity peened and nanoparticle added lubricant.
