FIELD: sliding bearing units with slit type inserts for turbine aggregates of heat power plants. SUBSTANCE: the most loaded portion of lower insert is provided with pocket separating working surface of that portion by two circumferential lands. Separation duct in outlet portion (according to rotation sign) of shaft is joined with radial oil draining duct. There is recess in mean cross section of separating pocket in direction to oil draining duct. At side turned to shaft said recess is provided with cover plate closing it. Recess is connected by means of by-passing ducts with non-through grooves provided on working surface of strips at both sides of pocket. A part of exhaust oil fed from separation pocket to recess passes through by-passing ducts into non-through grooves and returns on working surfaces of lands. EFFECT: enhanced conditions for lubricating bearing units in modes of emergency oil supply. 3 cl, 4 dwg
