The main purpose:

MRH-3 high-speed ring block wear test machine with sliding friction, soaked in oil lubrication condition, the lubrication performance evaluation of lubricants, especially suitable for high-grade automotive gear oil anti abrasion performance of the simulation evaluation, but also can be used for various metal and non-metal materials and coating the wear performance of the. This machine can be used for the determination of friction force, friction coefficient, connecting the computer, recording the temperature time curve, friction time curve. The machine is equipped with high precision measuring device can measure the friction, computer screen display, side wear spot measuring and recording.
