The use of polymers and polymer composites in various tribological situations has become state of the art. Nevertheless, further developments are still under way to explore new fields of application for these materials and to tailor their properties for more extreme loading conditions. This overview describes how to design polymeric composites in order to operate under low friction and low wear against steel counterparts. Particular emphasis is focused on the incorporation of spherical nanoparticles, often in combination with classical tribo-fillers, for the tribological improvement of thermoplastics and thermosets. The principle effects are demonstrated by describing practical examples of various fields of application. These include (a) high temperature polymer composite coatings for hybrid bushings used in automotive components under the hood, (b) friction torque limiters for damped flywheel clutches in modern automotives, (c) epoxy based particulate composites for thick covers of calendar rollers in the paper making industry, and (d) thersetting nanocomposite coatings for automotive engine pistons, to mention only a few.
