The Ring-on-Block Friction and Wear Tester (Model 2M) is a specialized instrument for evaluating the sliding friction and wear performance of materials and surface coatings. The tester utilizes a standard ring-on-block (shaft-bearing) friction pair to accurately measure friction coefficient, wear volume, and wear resistance under varying contact pressures and rotational speeds. The testing process is computer-controlled, ensuring stable data acquisition and high measurement accuracy. The instrument is suitable for research laboratories and industrial quality control.
