Hydraulic systems are the backbone of modern industries where power and motion are generated through fluid technology. The fluid that makes this possible is known as Hydraulic Oils. From construction machinery to manufacturing plants, hydraulic oils ensure smooth, safe, and efficient operations.
At Shri Rattan Traders, we supply high-performance hydraulic oils designed to protect equipment, improve productivity, and extend machinery life. In this guide, we answer the most common questions about hydraulic oils, their types, properties, and benefits.
WHAT IS HYDRAULIC OIL?
Hydraulic oil is a specially formulated fluid used to transmit power in hydraulic systems. It is much more than just a lubricant. It performs several critical functions:
- Transfers power within the system
- Lubricates moving components
- Acts as a sealant
- Cools internal parts
- Removes contaminants
- Prevents corrosion and rust
Hydraulic systems operate on the principle that liquids are nearly incompressible. When pressure is applied, the hydraulic oil transfers force efficiently, allowing heavy loads to be lifted or moved with precision.
If properly selected, hydraulic oils reduce wear, improve system efficiency, and significantly extend maintenance intervals.
TYPES OF HYDRAULIC OIL AND THEIR USES
Hydraulic oils are classified based on base oil composition and application requirements.
MINERAL-BASED HYDRAULIC OIL
Mineral hydraulic oils are derived from refined crude oil. They are enhanced with additives that provide:
- Anti-wear protection
- Oxidation resistance
- Rust and corrosion prevention
- Improved viscosity stability
These oils are cost-effective and widely used in industrial machinery, construction equipment, and agricultural systems.
SYNTHETIC-BASED HYDRAULIC OIL
Synthetic hydraulic oils are chemically engineered to deliver superior performance. They offer:
- Excellent high-temperature stability
- Longer oil life
- Better oxidation resistance
- Improved cold-weather performance
They are suitable for demanding applications where machinery operates under extreme conditions.
FIRE-RESISTANT HYDRAULIC OIL
Fire-resistant hydraulic oils are used in high-risk industries such as:
- Mining
- Steel manufacturing
- Aviation
- Die-casting operations
These oils reduce fire hazards while still maintaining lubrication and power transmission properties.
RAPIDLY BIODEGRADABLE HYDRAULIC OIL
Biodegradable hydraulic oils are designed for environmentally sensitive areas such as:
- Forestry
- Marine systems
- Earthmoving equipment
- Construction near water bodies
They break down naturally and help reduce environmental impact without compromising performance.
FOOD-GRADE HYDRAULIC OILS
Food-grade hydraulic oils are formulated for use in food processing plants where incidental contact with food may occur. These oils meet strict safety and hygiene regulations.
ADDITIVES IN HYDRAULIC OILS
The performance of hydraulic oils largely depends on additive packages.
