This graduate thesis talks about sliding bearings, parts of each machine or engine that allow long-term rotation of journal or shaft. Work covers concepts and explanations related to the purpose, constructional design, sliding bearing wear mechanisms and the actual analysis of sliding bearing used in the (non)combat vehicle military technique. The concept of work is divided into five chapters to show how the design itself and the choice of sliding bearing is very demanding procedure. The first chapter presents the introduction to graduate thesis, followed by a description of the purpose, the choice of material and the design of the sliding bearings. In the third chapter, the mechanisms of damage are listed, the types and appearance of the damage as well as the analysis of the failure of the sliding bearings. In the fourth chapter, an analysis of worn wear of a sliding bearing of a (non)combat vehicle of military technique was carried out, where the material of the bearing sleeves, the bearing shell wear pattern and the working conditions of the sliding bearing shell were analyzed, also proposing possible measures for achieving greater waer resistance were given. At the end of the work, a conclusion was drawn that emphasizes the importance of choice between materials and constructional designs when slide bearing is made as well as comments on the performed analysis.
