Abstract: Problem statement and its connection with important scientific or practical tasks. The search for technical solutions aimed at improving the reliability of connections of parts of ship's technical means (STM) is a topical issue in the design and operation of ship systems. The necessary level of safety and reliability is laid down at creation of ship knots and units, in the course of operation only support of the parameters set at designing due to the correct maintenance and repair that is connected with time and financial expenses is possible. One of the ways to increase the reliability of joints of STM parts is to increase their service life by increasing their wear resistance. There is a lot of research work aimed at improving the anti-wear properties of the surfaces of the connection "sliding bearing", their geometry, materials and technologies of their manufacture. Design experience shows that changing the profile of the contact surfaces several hundredths of a millimeter changes the contact planes and pressures by 2 ÷ 5 times and significantly affects the distribution of internal force factors. The purpose of this study is to determine the patterns of wear of the surfaces of the connection "shaft-sliding bearing". [1] Key words: ship technical means, microgeometry of a surface, frictional fatigue, connection "shaft-sliding bearing", radius of curvature of a wave.
