In the article the authors reveal technical solutions to increase the efficiency of inverted plain bearings with typesetting inserts made of thermoplastic composite materials by determining their rational parameters. The working hypothesis of the research was the postulate that the efficiency of composite polymeric materials is determined not only by high physical and mechanical and other properties, but also by the rational design of the friction unit. In the article, the authors proposed the developed experimental design of the inverted plain bearing, which differs from the existing ones in that the plastic inserts of the plain bearing are made in the form of prisms with a rectangular cross section, one side of which is an arc. The authors present analytical dependences that allow to determine the load that is perceived by the most loaded liners under the simplest load condition and a purely radial load applied to a radial bearing having a contact angle. The article reveals the results of laboratory tests and found that the total linear wear of the bearings of the sliding bearing in the form of inverted friction pair at 100 hours of continuous operation in a grease environment is 20…25% less than the bearing in the form of direct friction pair.
