One.Product Description:

  SGW-10A computer control automatic 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 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.The wear resistance of metallic materials or non-metallic materials can also be studied with special attachments.

  The “one button full-automatic ”of  high allocation four ball machine  can quickly and automatically lock the pb/pd value, which can save a lot of working time and steel ball, and is efficient for testing institutions and scientific research institutions.
