In a paper the results of effect the developed making technology on the antifriction properties of new bearings on the nickel alloy EP975-based composite materials with solid lubricant CaF2 additions for high speed printing equipment have been presented. Paper summarizes the formation of new materials’ structure and antifriction properties after new manufacture technology using. It was shown the efficiency of developed making technology for bearings that is confirmed by the results of industrial tests. The results of new composite material’s tribotechnical properties in a comparison with known nickel composite have been presented. Full-scale industrial tests of the new composite bearing materials in friction units of printing machines have been conducted. Visual inspection and measurement of surface roughness show that the contact surfaces of bearings are not damaged, have high quality, and are usable. Industrial tests of ЕP975–CaF2 bearings showed increase in wear resistance by a factor of 3.2 – 6.0 compared with known bearings.
