Determination of wear resistance of new greases

With the development of The Times, the new generation of grease wear resistance measurement methods have also changed. Let's discuss how to measure it! A new generation method for measuring wear resistance of lubricating grease (four-ball machine method (SH/ T0204-92)). This method uses test temperature (75(1.7); Speed (120050) r/min) load) 3922) N; At the end of the test, the average diameter of the three ball marks was measured.

Grease extreme pressure measurement method (four-ball machine method) SH/T0202-92) under the specified load, the above steel ball rotates down the static three steel balls, the speed is (177060) R /min the grease temperature is (278))
