In the paper there is presented an investigation on the subject of the substitution of materials used for manufacturing monometallic one-piece sliding bearings. The most widely used material for their manufac-turing is bronze of BrO4Ts4$17 grade which has rather high values of antifriction and strength properties. A whole complex of materials based on aluminum alloys is under consideration. There were investigated eight experimental alloys different with chemistry. In the paper there is described a procedure for carrying out experimental investigations. The comparative tables of the influence of these or those elements upon tribological properties are shown. An evident advantage of aluminum alloys over a compared material – bronze of BrO4Ts4S17 grade is identified. The following tribo-technical properties of experimental alloys such as score-resistance, conformability, durability, frictional moment are considered. Key words: aluminum antifriction alloys, bronze, stress-strain properties, strength, hardness, tribotechnical properties, conformability, scoreresistance, durability, secondary structures.
