Hydraulic Oil
Trent's range of grease lubricants is manufactured to deliver dependable performance in demanding industrial applications. Developed to high standards, our products provide reliable protection against wear, friction and corrosion, helping to maximise machinery performance and minimise downtime.
Hydraulic oil, also known as hydraulic fluid, is a specially formulated lubricant used to transfer power within hydraulic systems. It enables smooth and efficient movement of machinery components while also providing cooling and corrosion protection.
Hydraulic oil acts as both a power transfer medium and a lubricant. It reduces friction and wear, protects against rust and oxidation, removes heat from the system and helps seal internal components to maintain system pressure.
Common types include mineral-based, synthetic and biodegradable hydraulic oils. Each type offers different advantages. For example, synthetic fluids perform better in extreme temperatures, while bio-based options are environmentally friendly alternatives.
Mineral hydraulic oils are refined from crude oil and provide reliable performance in standard applications. Synthetic hydraulic oils are chemically engineered for enhanced stability, longer service life and superior performance in demanding or high-temperature conditions.
Biodegradable hydraulic oils are made from synthetic esters or vegetable-based materials. They provide effective lubrication while breaking down naturally in the environment, making them ideal for use in sensitive areas like agriculture, marine and forestry operations.
The correct hydraulic oil depends on your system’s pressure, temperature range and operating environment. Check the manufacturer’s specifications for viscosity grade (e.g., ISO VG 32, 46 or 68) and performance standards such as DIN or ISO classifications.
This depends on the application, working conditions and oil quality. Regular monitoring of oil cleanliness and oxidation levels can help determine when a change is due. Synthetic oils typically last longer than mineral types.
Mixing hydraulic oils is not recommended, as it can affect performance and stability. If switching oil types or brands, fully drain and flush the system before refilling with the new oil to prevent contamination.
Signs include reduced system efficiency, unusual noise, increased operating temperature, discolouration or a burnt odour. These indicate oxidation, contamination or water ingress. All of these issues can damage hydraulic components.
Store hydraulic oils in a clean, dry environment away from direct sunlight, moisture and temperature fluctuations. Keep containers tightly sealed to avoid contamination with dust, dirt or water.
Yes. Used hydraulic oils should be collected and processed through approved recycling or disposal facilities. Never release used oil into drains, soil or waterways, as it can cause serious environmental harm.
