The MRH-3 high-speed ring block friction and wear testing machine uses sliding friction and ring block wear to evaluate the sliding friction coefficient of metal materials and the lubrication performance of various lubricants under oil immersion lubrication conditions. It is particularly suitable for evaluating the anti scratch performance of medium and high-end automotive gear oils, as well as for evaluating the lubrication performance of solid lubricating materials and conducting wear tests on various metal and non-metal materials.
