First, product introduction:

MMW-1A friction and wear tester is a frictional form with rolling, sliding or sliding rolling under certain contact pressure. It has a stepless speed regulation system and can be used to evaluate the friction and wear properties of lubricants, metals, plastics, coatings, rubber, ceramics and other materials, such as low speed pins, at very low speed or high speed. The disc (with a large plate and small plate, single needle and three needle) friction function, four ball long anti wear performance and four ball rolling contact fatigue, ball - Bronze three lubrication performance, and thrust washer, ball - disc, mud wear, rubber seal ring seal moment and stick slip friction performance test. The test machine has a wide application in the field of tribology, petrochemical, mechanical, energy, metallurgy, aerospace, colleges and universities, research institutes and other departments.
