Four Ball Wear Tester

Applicable Testing Standard:
- GB/T12583-98 lubricant extreme pressure performance measurement (four ball machine method)
- GB3142-82 lubricant bearing capacity measurement method (four goals)
- SH/T0189-92 lubricant anti-wear performance measurement (four ball machine method)

Overview:
Out Computer control four ball friction testing machine, 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 non seizure 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.
