Four Ball Wear Tester for Grease

KR-AW20 automatic four-ball machine Lubricating grease anti-wear tester is in the form of sliding friction and is mainly used to evaluate the load-bearing capacity of lubricants under extremely high point contact pressure conditions. Including the maximum non-seizure load Pb, sintering load Pd, comprehensive wear value ZMZ and other three indicators, in actual applications, different evaluation indicators can be selected according to the various uses of the lubricant. The four-ball friction tester can also do long-term anti-wear tests of lubricants, determine the friction coefficient, and record friction and temperature curves. With special accessories, simulation tests of end-face wear and materials can also be carried out. The design principle of this machine is based on the loading stability of the lever four-ball machine, combined with the loading characteristics of the servo valve. The servo motor, air spring, and closed-loop control software can realize automatic resetting, automatic loading, automatic maintenance, automatic testing, automatic unloading, automatic Measure the wear scar diameter and take pictures, one-key operation, one-key data storage, fast test speed, minimal error, good repeatability, no pollution, no noise, and high efficiency.
