In order to study the tribological properties of different hydraulic oils under different motion modes, four-ball tester and block-on-ring tester were used to optimize the test parameters and evaluate performance of commercial hydraulic oils. The results showed that the optimized test methods under the form of point and line motion modes can better evaluate the extreme pressure and anti-wear performance of hydraulic oi. There was a negatively correlation between extreme pressure and anti-wear performance; this method can provide a basis for the reasonable selection of lubricating oil in hydraulic system.
