Using the developed methodology for calculating hybrid (metal-polymer) plain bearings, a study of the effect of temperature on the contact parameters and their resource was conducted. Metal-polymer bearings with a bushing made of polyamide PA6 reinforced with glass or carbon dispersed fibers were considered. The calculation of the maximum initial contact pressures and their change due to wear of the bushing was performed. The predictive estimate of resource of the investigated bearings at various loadings was carried out. Quantitative and qualitative patterns of changes in the maximum initial contact pressures and bearing resource with increasing temperature were established. Studies show that the decrease in the modulus of elasticity due to increasing temperature leads to a decrease in the maximum pressure and increase the resource of metal-polymer bearings, which is useful. This phenomenon is due to a decrease in the rigidity of the polymer composite.
