Popis:	The method of calculating the contact strength and service life of cylindrical metal-polymer sliding guides (linear bearings) based on the author's research methodology of the wear kinetics of materials during sliding is given. The influence of load, bushing diameter and radial clearance on the maximum initial pressures in the guide is investigated. According to the developed mathematical model of wear the estimation of influence of composite bushing wear on change of contact parameters such as initial contact pressure and contact angle is carried out. The prediction calculation of guide service life depending on the above-stated factors is also carried out. Quantitative and qualitative regularities of influence of the accepted factors on contact pressure and service life of metal-polymer sliding guides are established.
