FIELD: mechanical engineering.
SUBSTANCE: invention relates to the field of mechanical engineering, in particular to plain bearings, and can be used in chemical, energy, aviation, transport and other industries in a wide temperature range. The sleeve bearing contains a hollow shaft (2), a bushing (1) with cavities for powder lubrication and a loosening unit. The sleeve (1) is made of a structural material with a low coefficient of thermal expansion. The loosening unit is made in the form of depressions (4) distributed over the cylindrical surface of the shaft (2), connected by radial channels (5) with an axial channel (6) made in the shaft (2). The axial channel (6) is in communication with the gas source, and the radial channels (5) are made inclined towards the shaft rotation.
EFFECT: improving manufacturability and expanding the temperature range of work.
