Overview

The SH120 fully automatic four ball machine lubricant anti wear tester is mainly used to evaluate the bearing capacity of lubricants in the form of sliding friction under extremely high point contact pressure conditions. Including three indicators: maximum non card bite load Pb, sintering load Pd, and comprehensive wear value ZMZ, different evaluation indicators can be selected according to the various uses of lubricants in practical applications. This four ball friction testing machine can also perform long-term wear resistance tests on lubricants, measure friction coefficients, and record friction and temperature curves. Equipped with a dedicated wear spot measurement system, it can achieve the calculation screen display, measurement, and recording of friction pair wear spots. Special attachments can also be used for simulating end face wear and material testing. 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. Through the use of servo motors, air springs, and closed-loop control software, it achieves automatic zeroing, automatic loading, automatic holding, automatic testing, automatic unloading, automatic measurement of the diameter of the wear spot and taking photos. With one click operation and data storage, it has fast testing speed, minimal error, good repeatability, no pollution, no noise, and high efficiency.
