ASTROL HYDRAULIC OIL AW68

Alef Grup Astrol Hydraulic Oil AW 68

Hydraulic systems play a vital role in high-pressure applications such as construction equipment, agricultural machinery, industrial presses, and heavy-duty machines. To ensure these systems operate efficiently, safely, and with a long service life, selecting the right hydraulic oil is essential.

Alef Grup Astrol Hydraulic Oil AW 68 is a high-performance hydraulic oil formulated with Anti-Wear (AW) additives and designed with an ISO VG 68 viscosity grade. It delivers superior performance in medium- to high-pressure hydraulic systems, reduces wear, and helps extend overall system life.

Hydraulic mechanisms operating with piston, gear, and vane pumps are constantly exposed to high pressure, variable loads, temperature fluctuations, and extended working hours. Under these demanding conditions, the use of a reliable hydraulic oil becomes indispensable for maintaining operational efficiency and safety.

Developed specifically for medium- and high-pressure systems, Astrol Hydraulic Oil AW 68 is particularly suitable for machinery operating under heavy-duty conditions. Its ISO VG 68 viscosity ensures the formation of a strong oil film, minimizing friction and supporting consistent lubrication.

What Is AW 68 Hydraulic Oil?

AW (Anti-Wear) Additives:
Help prevent wear on metal components within the hydraulic system—especially piston, gear, and valve pumps—extending system life and lowering maintenance costs.

ISO VG 68 Viscosity:
With approximately 68 cSt viscosity at 40°C, it forms a durable oil film under high pressure and heavy loads, effectively reducing friction.

Application Areas:
Suitable for piston, gear, and vane pumps; hydraulic presses; cranes; excavators; loaders; and other mobile or stationary hydraulic systems.

Designed for equipment operating under heavy loads and high temperatures, AW 68 provides stable performance across a wide temperature range.

Technical Features and Advantages

Superior Wear Protection:
AW additives protect piston, gear, and valve pumps from metal damage even under intense pressure, extending pump and cylinder life while preserving system performance.

High Temperature and Oxidation Resistance:
Hydraulic oils naturally face oxidation during prolonged operation. Astrol AW 68, formulated with high-quality base oils and advanced additives, resists oxidation, varnish, and sludge formation—helping keep the system clean and efficient.

Corrosion and Rust Prevention:
Metal components in hydraulic systems are vulnerable to moisture and water exposure. AW 68 contains rust inhibitors that reduce maintenance costs and support long-term durability.

Multi-Purpose Usability:
Suitable for both stationary and mobile hydraulic systems, providing dependable lubrication for cranes, excavators, loaders, forklifts, and industrial presses.

Excellent Water Separation and Anti-Foam Properties:
Water contamination can lead to emulsification and foam formation. AW 68 separates water quickly and uses anti-foam additives to maintain consistent hydraulic performance.

Stable Viscosity Across a Wide Temperature Range:
Its ISO VG 68 viscosity helps preserve lubrication and flow characteristics in both low and high temperatures, ensuring reliable operation in diverse climates.

Thermal Stability and Long Shelf Life:
Resistant to high temperatures and capable of maintaining its properties during long-term storage, offering logistical and inventory advantages.

Suitable Systems

• Industrial Applications: Hydraulic presses, injection and molding machines, machining equipment

• Construction and Agriculture: Cranes, excavators, loaders, forklifts, tractors, and other heavy-duty machinery

• Mobile Hydraulic Systems: Truck-mounted cranes, hydraulic lifting systems, and mobile work equipment

• Pump Types: Piston, gear, and vane pumps

Benefits of Using Astrol AW 68

Extended System Life:
Reduces the effects of wear, corrosion, and oxidation, prolonging pump and cylinder lifespan.

Lower Maintenance Costs:
Minimizes sludge, deposits, and rust formation, helping extend maintenance intervals.

Efficient and Stable Operation:
Provides effective lubrication even under high pressure, improving system efficiency.

Wide Range of Applications:
Allows multiple machines and systems to operate with a single oil type.

Economic Advantage:
Fewer breakdowns and maintenance requirements translate into long-term cost savings.

Important Considerations and Application Tips

Check Compatibility:
Always confirm that your hydraulic system is suitable for AW 68, especially in sensitive valve and pump systems where manufacturer recommendations are critical.

Oil Changes and Filtration:
Regular oil replacement and filter checks prevent the accumulation of contaminants and metal particles.

Control Water and Moisture:
Although AW 68 separates water effectively, preventing water ingress into the system remains essential.

Choose the Correct Viscosity:
In extremely cold climates, lower viscosity oils such as AW 46 or AW 32 may be more appropriate.

Compliance with Standards:
Verify compatibility with standards such as DIN, ISO, Denison, and Vickers to ensure warranty protection and optimal performance.
