The machine can change temperature, load, speed, friction materials, friction surface roughness, hardness and other parameters and change the lubricant state (no oil lubricant, lubricant or oil immersed lubrication) in various cases, friction between the friction pair to achieve different simulation test.
 This machine can simulate rolling, sliding and rolling sliding friction composite movement form, with a variety of friction pair, such as pin on disk (with big disk and the small, single needle and three needle) firction pair, four ball friction pair, the thrust ring, ball on disc, etc. Can complete a variety of point, line, surface friction simulation experiment. Can be used to assess lubricant, metal, paint, coating, rubber, ceramics and so on friction and wear properties of metarials.
