Abstract: Literature review has revealed that operation lifetime of roller bearings is a factor determining reliability of automotive machinery. In order to increase the lifetime of roller bearings, it is proposed to modify their grease. This method can be applied during machinery operation and does not require for additional chemical–thermal and mechanical treatment of bearings involving complicated and expensive equipment. A modified grease was experimentally developed on the basis of Lithol-24, Russian standard GOST 21150-87 with nanosized metal particles obtained by plasma recondensation. Comparative tribological experiments of commercial grease and nanosized grease demonstrated efficiency of the latter. The acquired experimental results demonstrated that gamma-percentile life of the bearings operating with the developed grease was by 2.4–2.8 times higher than that of the bearings operating with the commercial grease.
