This grading system tells you the thickness of the oil and how it is affected by temperature.
Sae 10 weight hydraulic oil.
The higher the grade the thicker the oil and the less it flows.
Viscosity is the thickness of an oil.
Hartland hydraulic sae 10 and sae 20 is a new concept as 10 or 20 weight engine oils do not make very good hydraulic oils.
The higher the grade the thicker the oil and the less it flows.
Often the hydraulic oil for an older tractor is listed using an sae oil weight.
The viscosity of the fluid largely determines the oil temperatures within which the hydraulic system can safely operate.
This would not be a problem if hydraulic oils weren t labeled using the iso system now but they are.
Product description mobil hydraulic 10w is a high performance hydraulic oil formulated from advanced base oils and a balanced additive system designed to satisfy a wide range of heavy duty hydraulic equipment requirements.
Shell hydraulic s1 m 32 oil for hunter original fans only 22732.
Hartland hydraulic sae 10 and sae 20 meet or exceed the following manufacturer s specifications.
The sae society of automotive engineers created a classification table vi scale to show low to high viscosity levels depending on temperature c.
Oil with zinc has additional wear resistant properties to keep hydraulic pumps and equipment working even in high pressure systems.
Originally the scale only went up to 100 c but with advances in hydraulic oil blends the scale now goes above this number.
This heavy duty high pressure oil protects hydraulic jacks from corrosion and wear.
Sae 10w is equivalent to iso 32 sae 20 is equivalent to iso 46 and 68 and sae 30 is equivalent to iso 100.

Use this oil where zinc compatibility or environmental issues are a concern.
Phosphorus additives replace zinc to give it the wear resistance hydraulic pumps and equipment need even in high pressure systems.
As earlier mentioned sae stands for society of automotive engineers.

The higher the number the thicker is the oil.
In this case the 10 represents the thickness of the oil at operating temperature.
Sae established the grading system which includes a numerical code system.
