Effects of temperature on the properties of HL32 oil in the conventional hydraulic actuators.Present study pays more attention to optimize the performance of the hydraulic system by selecting the accurate position of the traditional hydraulic actuators.  It was used HL32 as working oil, due to its ability to withstand high temperatures (15-200) °C as well as having the best mechanical properties, since the density and viscosity are the most important factors that are extremely affected on the hydraulic system.  Hence, this work examined the effect of the variation kinematic, dynamic viscosity, and the density of HL32 oil on the accurate position of conventional hydraulic actuators.
