MRS-10A Computer Control Four Ball Friction Testing Machine



This machine is used to evaluate the loading capacity of lubricants in the process of sliding friction on a constant point under high pressure. The above-mentioned capacity includes: Maximum load PB under unstuck condition, sintered load PD & comprehensive wearing parameter ZMZ. The machine can carry on abrasive wearing test for a long time to test the friction force and obtain the friction co-efficient of the materials. Equipped with special accessories, it can perform end-face friction test and analogue wearing test of materials. Connected with recorder, it can print the curves of Temperature-Time and Friction Force-Time. Equipped with special device, it can display, test and record the test results of grading crack of friction-pair through computer
