32 is thinner, No. 46 is medium and No. 68 is thicker. Generally speaking, if the temperature is low in winter, use #32 & #46 hydraulic oil with a lower viscosity, and use #68 hydraulic oil with a higher viscosity in summer.

What is the difference between AW32 and AW 68?

AW32 is approximately a 10 weight oil with the additives ▪ AW46 is approximately a 15 weight oil with the additives ▪ AW68 is approximately a 20 weight oil with the additives AW –provides many of the advantages of premium hydraulic oil at a moderate price.

What is the difference between ISO 32 and ISO 68 hydraulic oil?

Viscosity grades

ISO grades measure viscosity at 104°F(40°C). When you look at, for instance, ISO 32 hydraulic oil it will flow much more quickly than ISO 68 hydraulic oil. Different viscosities are better for different applications in the field.

Hydraulic oil 68 grade is most commonly used for hydraulics with vane-, piston-, or gear-type pumps, especially where pressures exceed 1000 psi. They can also be used to lubricate lightly loaded reciprocating compressors.

What does aw in AW32 mean?

AW stands for anti-wear – R&O oils with an anti-wear additive package.

SAE 10W is equivalent to ISO 32, SAE 20 is equivalent to ISO 46 and 68, and SAE 30 is equivalent to ISO 100.

How do I choose hydraulic oil?

Conclusion: how to select the right hydraulic fluid?
Select the right viscosity at the given operating temperatures to ensure the highest efficiency and to meet the system requirements.Select the suitable AW additives: Zn or Zn free anti-wear protection additives.Check on viscosity index.

What is ISO 32 oil?

What is AW ISO 32 hydraulic oil? AW Hydraulic Oil is premium grade oil designed for use in all hydraulic systems where anti-wear hydraulic oil is recommended. All grades are rust and oxidation inhibited and contain an effective anti-wear additive and anti-foam additives to release entrained air rapidly.

What is compatible with ISO 32 hydraulic oil? SAE 10W is equivalent to ISO 32, SAE 20 is equivalent to ISO 46 and 68, and SAE 30 is equivalent to ISO 100. As you can see, there is a bit of a difference between ISO 68 and SAE 30.

What is AW32 oil?

Clarity Hydraulic Oils AW 32 are formulated with premium base oil technology and an ashless (“zinc-free”) additive system that provides exceptional oxidation stability, water separability, foam suppression, and protection against wear, rust and corrosion.

Are all hydraulic oils the same?

Not all hydraulic fluid is the same.

Hydraulic fluid can come from conventional oil, but it can also be formulated from synthetic stock. Hydraulic fluid can also be glycol-based, a water/glycol mix, or even nearly 100% water in some applications.

What weight is AW32 hydraulic oil?

AW32 is approximately a 10 weight oil with the additives. AW46 is approximately a 15 weight oil with the additives. AW provides many of the advantages of premium hydraulic oil at a moderate price.

At what temperature does hydraulic oil burn? A typical petroleum based hydraulic fluid has flash point that range from 300 to 600 degrees fahrenheit and an auto ignition temperature of 500 to 750 degrees fahrenheit.

What weight is AW 68 hydraulic oil?

contains AntiFoam additives. AW32 is approximately a 10 weight oil with the additives ▪ AW46 is approximately a 15 weight oil with the additives ▪ AW68 is approximately a 20 weight oil with the additives AW –provides many of the advantages of premium hydraulic oil at a moderate price.
