MM-W1A vertical universal friction and wear testing machine

MM-W1A vertical universal friction and wear testing machine, its main purpose and function are similar to the US FALEX6# multi-purpose sample test machine (Multi-Specimen-Test Machine ), and with our company MM-W1 vertical universal The use of the friction and wear tester is basically the same.

 

The machine has a frictional form of rolling, sliding or sliding composite motion under a certain contact pressure. It has a stepless speed regulation system, which can be used to evaluate lubricants, metals, plastics, and coatings under extremely low speed or high speed conditions. Friction and wear properties of layers, rubber, ceramics, etc., such as low-speed pin plate (with large and small plates, single and three needles) friction function, four-ball long-term anti-wear performance and four-ball rolling contact fatigue, ball-bronze three-piece lubrication Performance, as well as tests for thrust washers, ball-disc and stick-slip properties.
