%X The decision of contact problems taking into account the wear process of nano- and macro-surfaces of sliding bearings of piston machines has great importance for forecasting their durability. Wear processes of the surfaces create tension change on the contact area. The paper focuses on the mathematical modelling of the wear process of the insert of sliding bearings made of self-lubricating material, taking into account contact deformation using the elements of nanomechanics. The differential equation of a contact condition of this bearing is deduced and solved. A method is developed to define the intensity of the wear of the insert of sliding bearings made of self-lubricating material. There is determined the expression for definition of dimensionless parameters of speed of wear of the surface of the insert of sliding bearing. The method developed for estimation of intensity of the wear process allows us to operate this process and to find the optimum value of wear of mobile couplings of sliding bearings.
