Antiwear Hydraulic Oil

Antiwear hydraulic oil (AW hydraulic oil) is a premium-grade hydraulic fluid specifically formulated to reduce wear in high-pressure, high-load hydraulic systems. The "AW" stands for Antiwear, indicating that the oil contains special additives—most commonly zinc dialkyldithiophosphate (ZDDP)—that protect metal surfaces from friction, scoring, and premature damage. These oils also provide excellent oxidation stability, rust and corrosion protection, foam resistance, and sludge control, making them ideal for demanding environments.

AW hydraulic oils are essential for the reliable operation of a wide range of hydraulic equipment, including pumps, valves, motors, and cylinders used in construction machinery, manufacturing equipment, agricultural vehicles, and industrial systems. Common applications include hydraulic presses, injection molding machines, CNC tools, forklifts, skid steers, excavators, loaders, cranes, backhoes, mining drills, tractors, and harvesters. Whether you're maintaining a fleet or servicing shop equipment, antiwear hydraulic fluid is critical for protecting components and minimizing costly downtime.

Common AW Hydraulic Oil Grades and Their Uses:

• AW 32 – A lightweight oil ideal for cold climates or precision indoor equipment requiring fast flow and low resistance.

• AW 46 – The most widely used viscosity, suitable for moderate temperatures and general-purpose hydraulic systems.

• AW 68 – A heavier grade for high-temperature or heavy-duty applications like loaders and excavators.

• AW 100 – Used in extremely hot environments or systems with high operating temperatures and slow-moving components.

• AW 150 – Designed for heavy industrial equipment where very thick, protective oil is required to maintain film strength under intense load.

All AW hydraulic fluids conform to ISO VG viscosity grades and are compatible with systems requiring antiwear protection, such as those operating under the standards of Denison, Vickers, Parker, Bosch Rexroth, and Eaton.

Available Packaging Options:

• 5-gallon pails – Great for shop and on-site service use

• 55-gallon drums – Ideal for standard industrial consumption

• 275-gallon totes – Best for bulk users and fleet maintenance operations
