The expediency of using parts made of polymer composites in moving joints of machines in the oil and fat industry is shown. The use of experimental moving joints provided an increase in the resource from 500 hours to 1080 hours minimum. Diagnostics of experimental moving joints revealed that some of them have signs of transfer of the composite material to the steel shaft. This is explained by the following factors: the presence of the transfer effect and operation at high temperatures of 140 °C. The operating modes of the equipment are maintained. Most of the experimental parts made of polymer-composite material are in a running-in state, as wear has not been recorded in them.
