What is AW32 Hydraulic Oil?

AW32 is a specific grade of hydraulic oil defined by its viscosity. The “AW” stands for “Anti-Wear,” indicating that the oil contains additives designed to reduce friction and wear in hydraulic systems. The “32” refers to its kinematic viscosity at 40°C, measured in centistokes (cSt). This viscosity rating signifies the oil’s resistance to flow at a specific temperature.

Understanding Viscosity: The Key to Hydraulic Performance

Viscosity is the most important characteristic of hydraulic oil. It determines how easily the oil flows through the system, lubricates moving parts, and dissipates heat.

• Too Low Viscosity: If the oil is too thin, it won’t provide adequate lubrication, leading to increased wear and potential damage to the hydraulic pump and other components. It can also result in internal leakage, reducing the efficiency of the system.
• Too High Viscosity: If the oil is too thick, it will create excessive resistance to flow, leading to increased energy consumption, higher operating temperatures, and sluggish performance.

AW32 is a commonly recommended viscosity grade for log splitters because it strikes a balance between providing adequate lubrication and allowing for efficient operation in a wide range of temperatures.

Why AW32 for Log Splitters?

Log splitters typically operate under demanding conditions, including high pressures and varying temperatures. AW32 hydraulic oil is designed to withstand these conditions and provide reliable performance.

• Anti-Wear Additives: The anti-wear additives in AW32 oil form a protective layer on metal surfaces, reducing friction and wear. This is particularly important in log splitters, where the hydraulic pump and cylinder are subjected to high stress.
• Viscosity Stability: AW32 oil maintains its viscosity over a wide range of temperatures, ensuring consistent performance in both hot and cold weather.
• Oxidation Resistance: AW32 oil is formulated to resist oxidation, which can lead to the formation of sludge and varnish that can clog hydraulic systems.
• Corrosion Protection: AW32 oil contains corrosion inhibitors that protect metal components from rust and corrosion.

Alternatives to AW32: Choosing the Right Viscosity

While AW32 is a common recommendation, the ideal viscosity grade for your log splitter may vary depending on the manufacturer’s specifications and the operating environment. Always consult your log splitter’s owner’s manual for the recommended hydraulic oil type.

In colder climates, you might consider using a lower viscosity oil, such as AW22, to improve cold-weather start-up performance. In warmer climates, a slightly higher viscosity oil, such as AW46, may be more suitable to maintain adequate lubrication at higher temperatures.

Important Note: Never mix different types of hydraulic oil, as this can lead to compatibility issues and reduced performance.
