SH120 automatic four ball machine grease wear resistance tester is in the form of sliding friction, under the condition of extremely high point contact pressure, mainly used to evaluate the bearing capacity of lubricants.
In practical application, different evaluation indexes can be selected according to different uses of lubricants.
automatic lubricant grease four ball wear testing machine
The four-ball friction testing machine can also do lubricant long-term wear resistance test, determination of friction coefficient, record friction and temperature curves.
The use of special accessories, can also carry out the end face friction and material simulation test.
The machine design principle draw lever four ball machine load stability on the basis of the characteristics of the loading of the servo valve by servo motor, air spring, closed-loop control software to realize automatic reset, automatic loading, automatic stay, automatic test, automatic unloading and automatic measurement spot diameter and take pictures, a key operation, the data storage is a key save the test speed, small error, good repeatability, no pollution, no noise, high efficiency.
