MMW-1A Vertical Universal Friction & Wear Test Machine

MMW-1A Vertical Universal Friction Wear Test Machine is similar to an the FALEX MultiSpecimen Test machine in main application and functions, it’s widely used as imitation inspection testing machine in design and develop hydraulic oil, combustion engine oil, gear oil etc..

Perhaps the most versatile commercial system for evaluating friction, wear, and abrasion characteristics of materials, coatings, and lubricants. Numerous Standard Test Methods and Application Specific Custom testing programs are possible due to user selected contact geometries, motions, velocities, temperatures, contact pressures, and test specimen materials allow one test apparatus to meet many test specifications and simulate a broad range of field applications.

Applications include research and development, quality control, product qualification and the evaluation of physical and performance characteristics of materials, coatings, and lubricants. Test studies and a number of technical publications confirm exceptional correlation with field service.
