1. Core Performance

1. Wide Temperature Adaptability
   Operating temperature range: -73°C to 121°C. Maintains excellent startup performance in extreme cold (e.g., low starting torque at -73°C), meeting the low-temperature startup requirements of high-precision instruments. Outstanding oxidation stability at high temperatures ensures long-term reliability.

2. Extreme Pressure (EP) and Anti-Wear Properties
   Formulated with lithium soap-thickened synthetic oil and EP/anti-wear additives. Suitable for medium-to-heavy load applications, such as aircraft control system gears and transmission screws. Effectively reduces friction and wear, extending equipment lifespan.

3. Environmental and Safety Compliance
   Free of heavy metals (e.g., lead, cadmium) and nitrites, ensuring harmlessness to both the environment and human health. Complies with modern environmental standards.

4. Stability and Protective Performance
   Excellent colloidal stability, water resistance, and anti-corrosion properties. Protects metal surfaces in harsh environments (e.g., humidity, salt spray) to prevent rust.

2. Application Scenarios

1. Aircraft and Helicopters

• Control Systems: Moving joint boxes, bearings, and cockpit lock transmission components.

• Transmission Parts: Helicopter pins and specific transmission mechanisms.

• Gears and Screws: Heavy-load components like aircraft gearboxes and transmission screws.

2. Precision Instruments and Electronic Devices
   Used for bearings in instruments, cameras, and electronic equipment, as well as sliding surfaces of low-startup-power devices. Ensures stable long-term operation of precision components.

3. Import Substitution
   Complies with U.S. military standard MIL-G-23827B, serving as a domestic alternative to imported products like Aeroshell Grease 7. Reduces reliance on foreign products with significant economic benefits.

3. Standards and Certifications

• Domestic Standard: Chinese Military Standard GJB 942-1990.

• International Alignment: Meets MIL-G-23827B specifications and NATO standards.

4. Usage Precautions

1. Cleanliness and Compatibility
   Clean lubrication points thoroughly before application to avoid contamination. Conduct compatibility tests when in contact with plastic components.

2. Avoid Mixing
   Do not mix with other greases to prevent performance degradation.

3. Storage Requirements
   Store sealed in a clean, dry, and dark environment. Reseal containers after opening to prevent moisture or contaminants.

5. Technical Upgrades and Comparisons

• Upgrade Background: Replaces earlier models (e.g., 7008, 7012) with significantly improved low-temperature performance (-73°C) and high-temperature durability (121°C), achieving international advanced levels.

• Comparisons:

• Lubricant 7254: Contains molybdenum disulfide additives for higher-load scenarios (e.g., heavy-duty gears).

• Lubricant 7014: Designed for large passenger aircraft gears with superior low-temperature resistance.

6. Production and Supply

• Primary Manufacturer: Sinopec Research Institute of Petroleum Processing (RIPP).

• Packaging: 3.0 kg per canister, 6 canisters per box.

Summary: Lubricant 7253 has become a core material for domestic aviation equipment due to its wide temperature adaptability, high-load capacity, and eco-friendly properties. It is widely used in aircraft, precision instruments, and transmission systems, enabling import substitution and technological independence.
