Hydraulivoiteluöljy, often referred to as hydraulic fluid, is a crucial component in hydraulic systems. It serves multiple functions, including transmitting power, lubricating moving parts, cooling the system, and preventing corrosion. Hydraulic fluid is typically a mineral oil-based product, though synthetic and bio-based alternatives exist. The specific properties of the fluid are tailored to the operating conditions of the hydraulic system, such as temperature, pressure, and environmental considerations.

Key properties of hydraulic fluid include viscosity, which dictates its flow characteristics. Too low a viscosity can lead to leakage and reduced efficiency, while too high a viscosity can cause increased friction and heat generation. Thermal stability is also important, as hydraulic fluids must withstand high operating temperatures without breaking down or forming harmful deposits. Oxidation resistance is another critical factor, preventing the fluid from degrading over time due to contact with air. Additives are often incorporated into hydraulic fluids to enhance their performance, providing anti-wear protection, rust and corrosion inhibition, and improved demulsibility (the ability to separate from water).

The choice of hydraulic fluid is vital for the longevity and efficient operation of hydraulic machinery, ranging from construction equipment and manufacturing presses to aircraft control systems. Regular monitoring and maintenance of hydraulic fluid levels and condition are essential to prevent system failures and ensure optimal performance.
