These fluids are used in almost any industry that requires equipment and machinery for production with special fluid technologies for both mobile and stationary applications.
Types of industrial hydraulic oils and their applications
Here is a brief guide to the various kinds of industrial hydraulic oils and their diverse uses:
Mineral-based hydraulic oils
These come from fractions of crude oil and they also get refined to a stage where they accomplish suitable properties of lubrication. They are also boosted with suitable additives.
Mineral based hydraulic oils come with anti-oxidation, anti-rust, anti-wear, and other attributes. They are petroleum-based and are often low-cost choices for industries. They safeguard hydraulic machinery and systems against contamination by water, wear, and corrosion while enhancing the oil’s demulsifying properties and the overall viscosity index which enhances overall resistance to temperature changes.
Synthetic-based hydraulic oils
These oils were tailored for making up for the issues with the mineral oil variety. They are chemically produced and offer better performance, especially at higher temperatures. However, they may be costlier propositions in some cases.
Fire-resistant fluid-based oils
These industrial hydraulic oils are used for applications that have higher probabilities of fire, including mining, aviation, die-casting, and steel mills. They are comparatively more affordable than synthetic oils as well. The additive usage system enhances protection against corrosion while lowering foaming and friction alike.
Rapidly Biodegradable Hydraulic Oil
This segment meets new-age environmental standards while also ensuring better compatibility from an ecological perspective. They are used throughout mobile and stationary applications in forestry, industrial, tunnel building, mining, and earthmoving equipment. They come in several sub-types and categories.
Food-Grade Hydraulic Oils
These oils are tailored as per global regulations on additives and base oils alike. They also come with several sub-categories which are suitable for food industry usage where no direct contact happens with food. Several kinds of base oils are used for such lubricants.
STOU and UTTO Universal Hydraulic Oils
These are majorly used for the transmission systems of tractors and are widely used throughout the agricultural sector.
Aircraft Hydraulic Oils
These are used in the aviation sector and are known for their resistance to high pressure and extreme temperatures along with fluctuations. They come with excellent thermal stability along with a higher viscosity index as well. They also have fire-resistance properties along with being free from any contaminants.

How to choose the right industrial hydraulic oil grade
Industrial Hydraulic Oil- A Basic Guide
Industrial hydraulic oil is the cornerstone of any hydraulic machine. Naturally, such machines generate sizable quantities of heat and this may lead to issues with their motors and pumps while damaging internal hydraulic system components also.
This is where an industrial hydraulic oil helps greatly in working as a transfer medium, whereby power is transferred within the machinery seamlessly. Alternatively, these fluids may also function as coolants, sealants, and even lubricants. Thus, they have multiple uses in hydraulic brakes, excavators, power steering systems, and other industrial machinery.
All such fluids come with chemical additives fused to base oils. The additives help in enhancing the overall performance of these base oils while also boosting the overall performance of the components of hydraulic systems alongside. They can also work to enhance overall foaming resistance and corrosion resistance attributes while coming with water-resistance features. A majority of systems function with several types of fluids including multi-grade engine oil, automatic transmission fluids, and other regular anti-wear oils. Which grade should you choose? This will depend on your usage and equipment type.
Choosing the right industrial hydraulic oil grade- Viscosity grade concept
The viscosity grade is often the same name as the industrial hydraulic fluid grade. This is the most essential aspect when you choose any hydraulic fluid or oil. This is the be-all and end-all since the other properties will not make a difference if the viscosity grade does not sync with the system’s operational temperature range. Choosing the wrong grade will mean that your hydraulic system components become vulnerable to degradation or quick damage.
How to choose the right industrial hydraulic oil grade?
How can you choose the best possible industrial hydraulic oil grade? Here are some pointers that you should keep in mind:
- The starting viscosity that happens at the minimum ambient temperature.
- The expected maximum operating temperature is determined by the maximum ambient temperature.
- The optimum and permissible viscosity range for the components of a hydraulic system.
Here are the average values for viscosity requirements at permissible and optimum levels for specific components:
| Component Type | Minimum Permissible Viscosity (cSt) |
Minimum Optimum Viscosity (cSt) |
| Axial Pistons | 10 | 16 |
| External Gears | 10 | 25 |
| Internal Gears | 20 | 25 |
| Vanes | 25 | 25 |
| Radial Pistons | 18 | 30 |
When is multi-grade industrial hydraulic oil necessary?
In case your hydraulic oil has to function at freezing or chilly temperatures or even in tropical conditions during summer, then multi-grade industrial hydraulic oil will be a necessity for you. This will help maintain proper viscosity levels with permissible restrictions throughout a diverse spectrum of operating temperature ranges. If the viscosity of the fluid can be upheld throughout the optimal range, which is usually between 25-36 centistokes, then the total hydraulic system’s efficiency will naturally get a massive boost.
This will mean that in specific circumstances, the usage of these types of oils will lead to lower consumption of power for the system in question. This will mean lower consumption of fuel for any mobile hydraulic machinery as well. However, the VI or viscosity index should be carefully scrutinized, especially while dealing with mobile equipment which may have a smaller reservoir.
Turbulent flow and high shear rates may lead to scenarios where the molecular bonds are destroyed. When you choose, ensure that the minimum permissible viscosity values of the manufacturer are scaled up a minimum of 30% for making up for this aspect.
When is mono-grade hydraulic oil necessary?
You should use mono-grade industrial hydraulic oil in case of any system with a narrower range of operating temperature and also for maintenance of the optimal levels of fluid viscosity. These are situations where you should use a mono-grade option instead of multi-grade oil.
