1. A single- or multi-layer, longitudinal or transversal slide bearing, for uni- or bi-directional shaft movement, lubricated with liquid lubricants. It is characterised in that on at least one slide surface of the bearing, there are two layers of known lubricants, in the form of a liquid lubricant (3) and grease (4) with a smooth friction in the solid phase, permanently bound to at least one slide surface of the bearing, assuming the form of a 15 to 450 micrometer thick layer. Friction-generated heat is not carried away. A geometrical grid of indentations is made always on only one of the slide surfaces of the bearing. The indentations in the shape of V-blocks (5) with closed volumes or in the form of 1.5 mm deep transversal notches (6), and they cover from 40 to 75 percent of the slide surface. The surface is covered with grease (4) and liquid lubricant (3) which fill together the grid of indentations and cover the slide surfaces with a lubricating film. The film has the form of a volumetric high-pressure thermal-hydrostatic-hydrodynamic oil pad, with the interference of thermo-elastic oil volume expansion waves in closed indentations due to hydrostatic and hydrodynamic resistance of the indentation grid and to elastic deformations of the slide surface geometry. Geometrical structural elements (7) through (11) for feeding slide surfaces with liquid lubricant are shaped on the slide surface of the bearing shell. The elements have the form of a spherical lubricating recess or lubricating groove, which ends with a trepanation recess linked to lateral cut-outs. There are also spherical recesses near the edges of the slide surface of the bearing shell.
