The MMW-1 vertical multifunctional friction and wear testing machine uses sliding, rolling, and composite friction forms to select different friction pair forms for testing under a certain contact pressure, in order to evaluate the long-term wear resistance performance of lubricating oil and grease, as well as the friction and wear performance of metal materials. This machine is equipped with three types of friction pairs: four ball, pin plate, and thrust ring. According to user needs, various forms of friction pairs such as ball plate, ball three plate, pin three column, simulated cam, and gear can be provided.
