The article deals with the issues of the influence of accuracy parameters on the reliability and durability of assembly units of machine units. The accuracy of the connection is determined by the type of fit, formed gaps and tightness. Compliance with accuracy standards significantly reduces the level of external losses from marriage. However, a variety of deviations and tolerances of the elements of parts can lead to a wide range of fits, which is not economically viable. Insufficient accuracy can lead to damage to parts, leakage of liquids and gases, as well as to a decrease in the performance of the machine as a whole. Therefore, machine manufacturers are striving to improve the accuracy of the connection of parts and the use of more precise production methods. Seating systems simplify the manufacturing process and reduce the number of metal cutting tools needed.
