FIELD: mechanical engineering, in particular, structures of artillery guns. SUBSTANCE: the novelty in the ball bearing is the presence of a combination of screw and annular grooves filled with solid lubricant, which serve as lubricant reservoirs and through which abrasive materials are removed from the friction surface. EFFECT: enhanced reliability of artillery gun due to elimination of dry friction and reduction of abrasive wear in triboconjugations. 2 dwg
