AW 220 Antiwear Hydraulic Oil is a high-performance hydraulic fluid designed for use in a variety of hydraulic systems, providing superior protection and efficiency under moderate to high-pressure conditions. The "220" refers to the viscosity grade of the oil, and "AW" stands for Anti-Wear, indicating the oil's primary function of preventing wear on critical components. This oil is ideal for industrial, mobile, and heavy-duty machinery, where reliability and long-term operation are crucial.

1. Viscosity Grade (220):

   • The "220" in AW 220 hydraulic oil indicates the kinematic viscosity of the oil at 40°C, measured in centistokes (cSt). For AW 220, the viscosity is approximately 220 cSt at 40°C.

   • This viscosity grade is considered medium-to-high and is ideal for hydraulic systems that operate under moderate to high pressure and in moderate to high-temperature environments. It's commonly used in equipment that requires stable fluid flow at higher pressures, ensuring efficient operation of pumps, valves, and other hydraulic components.

2. AW Classification (Anti-Wear):

   • The AW classification means the oil is formulated with anti-wear additives, providing protection against metal-to-metal contact and reducing wear on critical hydraulic components such as pumps, motors, and valves. This ensures the longevity of the equipment and reduces the risk of failure due to wear-related damage.

   • AW oils also include additives to combat other issues such as:

     • Oxidation: Prevents breakdown of the oil at high temperatures, extending its operational life.

     • Corrosion: Protects internal system parts from rust and corrosion caused by water or moisture contamination.

     • Foam formation: Prevents air bubbles from forming within the oil, which can lead to inefficiencies and damage.

3. Additives:

   • Anti-wear agents: These additives create a protective layer on metal surfaces, preventing direct contact between moving parts and reducing friction, wear, and tear.

   • Oxidation inhibitors: Extend the oil’s service life by preventing it from breaking down under high temperatures, keeping the fluid clean and effective.

   • Rust and corrosion inhibitors: Prevent rust formation and corrosion in the system, which is particularly important in humid or wet conditions where moisture contamination is a concern.

   • Anti-foam agents: These additives reduce foam and air entrainment, ensuring that the hydraulic fluid flows consistently and efficiently, maintaining optimal system pressure.
