A dependence have obtained for determining the design tolerance of fit, as one of the characteristics of the model of parametric failure of a joint with an interference fit, the calculation is carried out taking into account the wear rate and the parameters of its dispersion at a certain resource and a given probability of failure-free operation. On the example of calculating a connection with an interference fit, it have shown that the choice of a fit without a margin of accuracy cannot ensure the operational reliability of the connection, but only guarantees the absence of failures at the initial stage of work – during the warranty period. It have proven that with the right choice of fit accuracy, it is possible to achieve a significant increase in the resource of failure-free operation.
