This research work uses the true viscous fluid flow equation for the thin layer, the continuity equation, and the equation describing the radius of the fused shaft coated with a metal alloy taking into account the mechanical energy dissipation rate formula to find the asymptotic and the exact self-similar solution for the zero and first-order approximation for the radial sliding bearing with the support profile adapted to friction and lightalloy coating for incomplete filling of the working gap. We obtained the analytical dependencies for the fused surface radius of metal coating and the speed and pressure field. Besides, we determined the key operating parameters of the reviewed friction couple, the carrying capacity, and the friction force. The authors assess the impact of the parameters associated with the fusing of the coating of the friction-adapted support profile and the length of the loaded area on the carrying capacity and the friction force.
