Background. The object of research is vacuum pumping systems as an example of complex technical systems. The subject of the study is to increase the reliability of vacuum pumping systems by replacing rolling bearings with sliding bearings made of modern nonmetallic composite materials. The purpose of the work is to consider the possibility of introducing non-metallic composite materials to optimize the physical properties of parts and assemblies leading to an increase in the reliability of elements and structural units of units.
Results. The brands of modern non-metallic materials and their characteristics are considered. The main criteria for the choice of antifriction material are determined, and methods are proposed that confirm the effectiveness of the proposed solution to increase the life of bearings in the friction nodes of complex technical systems. Examples of the introduction of polymer composite materials in various fields of engineering are given.
Conclusions. Wide temperature range and low values of friction coefficients of nonmetallic composite materials will allow to extend substantially the life cycle of the friction nodes of complex technical systems, thereby increasing the reliability of the system operation.
