FIELD: machine building.
SUBSTANCE: self-lubricating sliding bearing contains a metal bush with antifriction polymer coating, at that on the internal surface of the metal bush the ring grooves are made with profile in form of the dovetail, and in them the longitudinally closed resilient elements are installed. The ring grooves with the installed closed resilient elements are filled with antifriction coating. The closed resilient elements are made in form of the hollow rubber rings with the internal and external metal braiding. The outside diameter of the rubber ring does not exceed the minimum width of the ring groove. The rubber ring cavity is filled with paraffin.
EFFECT: increased durability, wear resistance and impact resistance of self-lubricating sliding bearing.
