Product Details

SH120 automatic four-ball friction testing machine,The design principle of this machine absorbs the stability of the lever four-ball machine andand combines the loading charcteristics of the servovalve.Automatic zero clearing, automatic loading, automatic holding, automatic test, automatic unloading, automatic measuring and taking pictures of spot diameterare realized by servo motor, air spring and closed-loop control software. one-click operation, data storage and one-click storage.

in the form of slide friction, is used for the loading capacity evaluation of lubricants in the high pressure point contact condition. It can test the maximum nonseizure load PB, sintered load PD and composite wear value ZMZ of lubricants .The four-ball friction test machine can also be used as lubricant for long time wear resistance test, determination of friction coefficient, recording friction and temperature curve. It also can measure the dimension of the wear scar and display,measurement and recording the wear scar on the PC screen.
