1. applications

The MMW-1A Universal Friction and Wear Testing Machine evaluates the friction and wear performance of lubricants and various materials under a specific contact pressure through sliding, rolling, and combined motion friction forms. Based on customer requirements, it can be equipped with multiple friction pairs, including pin-on-disk (with large and small disks, single and triple pins), four-ball, thrust ring, ball-three-plate, pin-three-plate, simulated cam, and gear configurations, enabling diverse friction and wear tests. Leather friction testing can be achieved using the pin-on-disk friction pair, where the disk fixture holds the leather sample and the pin fixture holds the test specimen. This machine can operate under extremely low or high-speed conditions to assess the friction and wear performance of materials such as leather, lubricants, metals, plastics, sandpaper, coatings, rubber, and ceramics. It is widely applicable in tribology-related fields and meets the needs of industries like petrochemicals, machinery, energy, metallurgy, and aerospace for developing, testing various mid-to-high-end oil and grease products, as well as emerging materials and new processes in friction and wear testing.
