ASTM D2266 ASTM D4172 Computer-controlled Four-ball Friction Wear Tester ASTM D2783 Lubricant Extreme Pressure Test Machine

PRODUCT INTRUDUCTION

Overview The computer-controlled four-ball friction and wear testing machine complies with the test methods specified in GB/T 12583, GB/T 3142, NB/SH/T 0189, SH/T 0202, SH/T 0204, ASTM D2783, ASTM D2266, and ASTM D4172. It is designed to evaluate the load-carrying capacity of lubricants under conditions of high point-contact pressure involving sliding friction. Key performance indicators include the non-seizure load ($P_B$), the weld load ($P_D$), and the wear scar diameter/wear index. The machine can also be used to conduct long-duration anti-wear tests for lubricants and to measure the coefficient of friction. Features 1. Large-screen panel control 2. Equipped with a toolbox
