1.Introduction

MRS-10A computer control Four-Ball Tester  , 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. It can record frictional force and temperature curves. It also can measure the dimension of the wear scar and display the wear scar on the PC screen.
