7023 Low Temperature Aviation Lubricating Grease

Reliable Low-Temperature Protection for Critical Aviation Systems

SINOPEC 7023 Low Temperature Aviation Lubricating Grease (also known as Great Wall 7023A) is a high-performance, multi-purpose low-temperature grease developed specifically for aviation and precision mechanical systems operating under extremely cold conditions. It is formulated with synthetic base oil thickened by an organic gelling agent, combined with carefully selected anti-oxidation, anti-rust, and corrosion-inhibiting additives, ensuring stable lubrication, protection, and reliability over a wide temperature range.

Designed to meet demanding aerospace standards, 7023 aviation grease complies with GJB 2660-96 (Type B) and GOST 6267-74, making it suitable for both military and civil aviation applications, as well as other precision equipment exposed to severe low-temperature environments.

Outstanding Low-Temperature Performance

One of the key advantages of SINOPEC 7023 is its exceptional low-temperature fluidity and torque performance. With a similar viscosity of only 744 Pa·s at –50°C, the grease remains workable and pumpable even under extreme cold, ensuring reliable lubrication during cold starts and continuous operation in high-altitude or polar environments. This significantly reduces start-up resistance, wear, and the risk of lubrication failure.

Excellent Protection and Lubricity

7023 aviation grease provides superior rust prevention and corrosion protection, effectively shielding steel and copper alloy components from moisture, oxidation, and aggressive environments. The product passes copper corrosion and protective performance tests, confirming its suitability for long-term metal protection.

Its excellent lubricity and load-carrying capability help reduce friction and wear in bearings, sliding surfaces, and moving mechanisms, extending component service life and lowering maintenance costs. This makes it especially suitable for aviation systems where reliability and safety are critical.

High Stability and Adhesion

The grease exhibits excellent colloidal stability and mechanical stability, preventing oil separation, softening, or leakage during long service intervals or under vibration. With a high drop point of 244°C, 7023 maintains structural integrity under temperature fluctuations.

In addition, its strong adhesion ensures the grease remains firmly attached to lubricated surfaces, even in complex or vertical assemblies, preventing grease loss and ensuring continuous protection.

Typical Applications

SINOPEC 7023 Low Temperature Aviation Lubricating Grease is widely used for the lubrication, protection, and preservation of aviation components, including:

• Aircraft gun systems

• Landing gear retraction and extension mechanisms

• Aircraft control and operating systems

• Bearings and sliding parts requiring low-temperature performance

Operating temperature range: –60°C to +120°C

Handling and Storage Recommendations

• Clean all lubricated parts thoroughly before application.

• Do not mix with other greases, as incompatibility may cause performance degradation.

• Seal the container promptly after use to prevent contamination by moisture or dust.
