Ball-on-disc instrument for measuring the frictional properties of lubricated and unlubricated contacts under extreme pressures and a wide range of rolling and sliding conditions.
The unique ball and disc set up enables mixed rolling and sliding conditions to be simulated. All three regimes ( boundary, mixed and EHL ) can be replicated whilst applying extreme load and realistic temperatures and speeds. The frictional properties of lubricants and additives can be analysed under realistic conditions for quick comparison between formulations.
The ETM System comprises a single integrated mechanical and electronic control unit, separate FES, cooler and power supply and a PC with data logging software
