Plain bearings are an important part of many large and critical units and assemblies used in the mining industry. They are widely used in power equipment, powerful pumps, compressors, electric motors and internal combustion engines (ICE). Plain bearings usually include an anti-friction bushing, part of the shaft surface (bearing journal) and an oil layer between them. These are complex and critical parts in which dangerous defects may occur and which directly affect the durability, accuracy and reliability of the entire assembly. To ensure high reliability of equipment with plain bearings used in complex equipment, it is necessary to ensure their quality control, as well as a sufficient level of monitoring the technical condition and diagnosing emerging defects. This is one of the main operational tasks that the personnel of the maintenance and diagnostic services of enterprises have to constantly solve. This paper presents a comparative analysis of the quality of plain bearings for internal combustion engines of various manufacturers. The performance properties of bearings are given depending on the composition. The results of chemical analysis of the base, cover and intermediate layers of ICE liners are presented. Comparative characteristics of plain bearings are given in terms of the chemical composition of the layers and their thickness for various manufacturers: Cummins POL (Poland), Cummins CCEC (China), WETZ (Russia). Recommendations are formulated to improve the performance of plain bearings.
