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))
