FIELD: mechanical engineering, in particular, structures of rocket-artillery armament. SUBSTANCE: the novelty in the plain bearing is the presence of annular heat-removing member, whose width equals the thickness of the bush, the inside diameter equals the outside diameter of the shell. EFFECT: enhanced reliability of armament specimens due to expansion of the field of application of polymeric composite materials in the friction assemblies by enhancing their heat-removing capacity. 1 dwg
