Grease and lubricant Four ball friction and wear testing machine
Brief Introduction: The machine is used to evaluate the loading capacity of lubricants in the process of sliding friction o na contact point under very high pressure. The above mentioned capacity including 3 datas to be tested: the maximum load PB under the unstuck condition, sintered load Pd and comprehensive value of wearing during friction ZMZ.
This testing machine composed by machine base, spindle drive, cylinder piston force system, hydraulic station, electronic control cabinet. All digital electric measurement amplification control system and liquid crystal display system. Real-time display test force, friction, speed , test speed, time and temperature.
