Abstract: The article considers the character of the pairing contact surfaces of the two bushings, made of alloy steel and aluminum alloy, with the guaranteed tightness (N = 0.03 mm) when pressing-in details at cold condition. The highest stress of the material is observed on the inner surface of the bushing of alloy steel in the direction of the coordinate axis Z on the part action of the efforts of pressing-in. This increases the strength of adhesion of the surfaces of the bushings on that side. Presents a comprehensive picture of changes in the direction of the velocity of deformation of materials in the longitudinal and transverse cross sections are pressed bushings. The maximum value of kinetic/internal energy ratio for bushing made of alloy steel is 22 at the end of the time range of the process of pressing-in.
Key words: bushing, pressing-in, stress, aluminium alloy, alloy steel.
