Choosing a Hydraulic Fluid and Viscosity

Viscosity is another major factor for choosing a hydraulic fluid. All the advantageous or exclusive properties of a hydraulic oil are useless if the viscosity grade of the oil is not in-sync with the operating temperature of the given system.Inappropriate viscosity can lead to under utilization of the potential component life. There are a number of factors involved in setting the appropriate fluid viscosity grade for a given hydraulic system, such as:

The initial viscosity at the lowest ambient temperature.Utmost anticipated operating temperature which is actually determined by the maximum ambient temperature.Proper and permissible viscosity range as per the components of the system.Though making a choice regarding the suitable hydraulic oil is a little difficult, hence, here are few tips which can help you make a definitive choice for the same that too according to your hydraulic system and application.
