A ball-on-disc instrument for measuring the frictional properties of lubricated and unlubricated contacts under a wide range of rolling and sliding conditions.
The MTM is our most versatile instrument with a wide range of applications, such as improving fuel economy and engine efficiency, developing new formulations for railway greases, reducing the wear of artificial joints, and perfecting the mouthfeel of food and the skin feel of cosmetics.
Optimizing the friction and wear properties of a system can significantly improve performance and reduce operating costs. Testing lubricants and materials under realistic contact conditions is imperative to understanding where improvements can be made. The unique ball-on-disc setup enables an unrivaled number of conditions to be simulated. All three regimes (boundary, mixed, and EHL) can be replicated, producing Stribeck curves. The test temperature, load, specimen material, and geometry can be chosen to further investigate component performance under realistic conditions.
The above features, combined with the unique capability of measuring antiwear film buildup throughout the test, have propelled the MTM to the position of an industry standard instrument among OEMs, lubricant manufacturers, and additive suppliers.
