Tribological properties of polymer-based journal bearings

Polymer-based materials are widely used due to their good corrosion resistance, self lubrication, and wear resistance properties at low speeds and but are not suitable for lubrication in journal bearings. High performance engineering polymers ensure desired properties for journal bearings and give good tribological results. In this study, tribological behaviors of polymer-based PE, PA, POM, PTFE, and Bakelite bearings have been investigated and evaluated. As a result, the highest wear resistance has occurred in PA and POM bearings.
