Great Wall® 7007 General Aviation Grease

Wide-Temperature, High-Speed Lubrication for Aviation and Precision Equipment
(Equivalent Performance to Klüber ISOFLEX LDS 18)

Great Wall® 7007 General Aviation Grease is a high-performance, multi-purpose lubricating grease originally developed for aviation applications and later widely adopted in precision industrial and civilian equipment. It is formulated by thickening high-quality synthetic base oil with a soap-based thickener system and enhanced with structural improvement agents and antioxidant additives. This advanced formulation provides excellent lubrication reliability over a wide temperature range and under high-speed operating conditions.

Designed to meet the stringent requirements of aviation lubrication, Great Wall® 7007 delivers stable performance in both extremely low temperatures and elevated operating environments. Its balanced physical and chemical properties make it suitable not only for aircraft-related components, but also for a wide range of high-speed bearings, precision spindles, and low-temperature machinery in non-aviation industries.

In terms of application performance, Great Wall® 7007 General Aviation Grease is equivalent to Klüber ISOFLEX LDS 18, and can be used as a direct substitute in many aviation and precision bearing lubrication scenarios.

Product Formulation and Design Concept

Great Wall® 7007 is based on a synthetic oil platform, providing excellent low-temperature fluidity and stable viscosity characteristics. The soap-based thickener system ensures good mechanical and colloidal stability, allowing the grease to adhere reliably to lubricated surfaces without excessive oil separation or grease loss. High-efficiency antioxidant additives further enhance resistance to oxidation, enabling the grease to maintain long-term stability during continuous operation at elevated temperatures.

For applications requiring enhanced corrosion protection, Great Wall® 7008—a related product in the same series—incorporates additional rust-preventive additives. However, 7007 remains the standard choice for general aviation and high-speed bearing lubrication where balanced performance is required.

Key Performance Advantages

Excellent High and Low Temperature Performance
Great Wall® 7007 operates reliably across a wide temperature range from -60°C to +120°C. At extremely low temperatures, it maintains sufficient fluidity to ensure smooth bearing start-up and reduced torque. At higher temperatures, it resists softening and degradation, allowing lubrication components to function normally under continuous thermal stress.

Outstanding Oxidation Stability
The grease exhibits excellent resistance to oxidation, preventing hardening, sludge formation, or performance deterioration during long-term operation. This characteristic ensures stable lubrication under sustained high-speed or moderately high-temperature conditions.

Superior Mechanical and Colloidal Stability
Great Wall® 7007 maintains strong adhesion to lubricated surfaces, even under high centrifugal forces generated by high-speed rotation. Its good mechanical stability prevents grease displacement, leakage, or excessive oil separation, ensuring consistent lubrication performance throughout service intervals.

Reliable Lubrication and Wear Protection
By forming a stable and continuous lubricating film, the grease effectively reduces friction and wear between bearing surfaces. This helps minimize noise, vibration, and bearing wear, contributing to longer service life and improved equipment reliability.

Applications

Originally developed as an aviation lubricating grease, Great Wall® 7007 is suitable for:

• Aircraft motor bearings and gears

• Operating mechanism pivots and assembly connections

• Lubrication of certain instruments and meters

• High-speed ball bearings

In non-aviation fields, it is widely used for:

• Grinding machine spindles operating at 5,000–20,000 r/min

• Spinning and twisting machine spindle bearings operating continuously at 2,000 r/min

• Airflow spinning spindle bearings at 3,600 r/min

• Bearings of outdoor electromechanical equipment in cold regions (e.g., DC generators)

• Instrument motor bearings

• High-speed household micro motors (electric shavers, crushers)

• Bearings of low-temperature liquid transfer pumps (methane and ethane reflux pumps)
