Good viscosity-temperature characteristics. Hydraulic tractor laser grader Viscosity-temperature characteristic refers to the degree to which the viscosity of the oil changes with the temperature, usually expressed by the viscosity index. The larger the viscosity index is, the smaller the viscosity of the oil in the hydraulic system decreases with the increase of temperature, Hydraulic tractor laser grader so that the internal leakage of the hydraulic system is not too large. The viscosity index should not be lower than 90.
Good wear resistance and lubricity. The purpose is to reduce mechanical friction and ensure that there is sufficient oil film strength under different conditions such as pressure, Hydraulic tractor laser grader speed and temperature.
