Hydraulic Oil
Hydraulics represent systems where energy and power are transferred through fluids. The fluids applied are called hydraulic fluids or hydraulic oils and are used in various types of machinery, equipment, and across industries. Moreover, hydraulic systems and components are applied in agriculture, construction, mining, steel, shipbuilding, aviation, aerospace industry, chemicals, medicine, food, environmental technology, and more. Name any industry in the world and there is a very high chance that it uses a type of fluid technology in stationary or mobile applications.

As with the majority of lubricants, we have the primary categorization into mineral and synthetic hydraulic oils. The first originate from petroleum, while the second are synthesized or created artificially. In addition, there are also fire-resistant fluid-based hydraulic oils that are particularly used in sensitive environments, biodegradable, food-grade hydraulic oils, STOU and UTTO universal mobile hydraulic oils, and aircraft hydraulic fluids.
Properties Of Hydraulic Oil
As we can see from the aforementioned categorization, hydraulic oils have to possess certain properties to be able to meet the requirements of the hydraulic systems and operating conditions. Whether it is heavy-duty or an application that does not have such extreme working conditions, hydraulic oil needs to be:
- non-compressible
- stable in terms of viscosity and in a range of operating and climatic temperatures (high and low)
- fire-resistant
- non-corrosive
- anti-wearing
- resistant to water contamination
- durable
Benefits of Hydraulic Oil
Each hydraulic oil is different and based on its intended application and additives package, it can offer different benefits.
- Protection against corrosion and rust. In other words, hydraulic oils are hydrolytically stable.
- Optimal operations even under extreme working temperatures and conditions thanks to the viscosity stability of hydraulic oils.
- Protection from foaming and formation of sludge and deposits. In return, the system's efficiency, reliability, and performance are increased.
