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 mouth feel of food and the skin feel of cosmetics.
Optimising 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 set up enables an unrivalled number of conditions to be simulated. All three regimes (boundary, mixed and EHL) can be replicated, producing stribeck curves. The test temperature, load and specimen material and geometry can be chosen to further investigate components performance under realistic conditions.
The above features combined with the unique capability of measuring antiwear film build up throughout the test, has propelled the MTM to the position of an industry standard instrument amongst OEM’s, lubricant manufacturers and additive suppliers.
