What is ISO 32 hydraulic oil?

Protects hard-working hydraulic systems from the stress of high-pressure, high-load and heavy-duty operations. Remains fluid in cold temperatures for immediate cold-weather flow. Special anti-wear additives and rust inhibitors provide optimum protection to expensive equipment.

What does ISO 32 mean?

The numbers indicate to the nearest whole number, the mid points of their corresponding brackets. For example, ISO viscosity grade 32 relates to the viscosity bracket 28.8 to 35.2 mm2/s, the mid point of which is 32.0 mm2/s.

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. The viscosity of the fluid largely determines the oil temperatures within which the hydraulic system can safely operate.

What does 32 mean in hydraulic oil?

The hotter the temperature, the thinner the oil becomes and the colder the oil, the thicker. So, for example, a hydraulic system operating in a cold climate like Tasmania would run better with a lower viscosity grade of 32. The oil would be thinner and have less resistance to flow on start-up.

Hydraulic Oil Types



What's the difference between ISO 32 and AW 32?

These oils perform at the same grade as their ISO counterparts. An AW 32 hydraulic oil is going to be at 32cSt at 40°C for instance. The difference here is that there are additives contained within the oil.

What does ISO stand for in oil?

ISO VG stands for “International Standards Organization Viscosity Grade” and is reported in numbers ranging from 2 all the way up to 1500. This number is critical because a lubricant's viscosity is the single most important factor when selecting the right oil for your machinery.

What is the difference between SAE and ISO?

There is no significant difference between ISO (International Standards Organisation) or SAE (Society of Automotive Engineering). Both organisations provide test standards to allow the ability to reliably compare published filter ratings among manufacturers.

What is the difference between ISO 46 and ISO 32 hydraulic oil?

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.

Can you mix AW32 and aw46 hydraulic oil?

"Is it all right to mix an R&O hydraulic oil with an AW hydraulic oil in a hydraulic application?" Mixing oils with different additive packages is never recommended. Doing so could compromise the additive performance of both constituents, cause corrosion of component surfaces and lead to increased mechanical wear.

What does ISO hydraulic mean?

Hydraulic oil grades

ISO VG – ISO Grade (where ISO is the International Standards Organisation) – the higher the VG number the more viscous the fluid is. The VG number tells you which hydraulic oil is thicker.

How do I read ISO numbers?

ISO codes show 3 sets of separated numbers. These numbers refer to ranges depicting the number of particles 'larger than' 4 micron, 6 micron and 14 micron per 1mL respectively. Obviously, as 6 micron and 14 micron particles are both larger than 4 micron, those particles are all also present in the first number.

Is AW 46 hydraulic oil the same as ISO 46?

ISO 46 simply refers to the vicosity. AW stands for "Anti Wear". Your AW Hydraulic Oil ISO 46 is going to be the same thing as AW-46. It's just that the words are rearranged in a different order.

Is AW 32 hydraulic oil the same as ISO 32?

AW 32 hydraulic fluids have an International Standards Viscosity Grade or ISO VG of 32. This is the thickness of the fluid tested at 40 degrees Celsius. ISO VG 32 has good cold weather flow capabilities and its thickness is equivalent to a SAE 10 weight lubricant.

Is all hydraulic oil the same?

Not all hydraulic fluid is the same.

Hydraulic fluid varies just as much as the fluids in your car. 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.
