The paper considers the application of polymer composite materials in friction units of downhole oil pumps. The proposed scheme test samples of various composite materials paired with a steel roller adopted by the size of the spots wear using the criterion of resistance. As it is shown significant influence on the wear resistance of the friction pair, working in the crude oil environment, has not only the composition but also the reinforcing fibers direction. The best re-sults were obtained for a sample of polyamide reinforced with 50 % of high molecular weight synthetic fibers placed perpendicular to the friction surface.
