What Is Aviation Grease?
Aviation grease is crafted to meet strict aerospace standards. Its core ingredients are:
- Base Oil: Provides the lubrication film. Options include synthetic esters or PAO for wide temperature performance.
- Thickener: Bentonite clay or lithium complex to maintain consistency under load and speedZhongTian.
- Additives: Extreme-pressure agents, anti-oxidants, rust inhibitors, and anti-wear compounds enhance protection.
General Aviation Grease 7008 by Zhongtian Petrochemical combines synthetic base oil with a high-grade thickener and specialty additives to deliver consistent performance from –60 °C to +120 °CZhongTian.
Key Performance Features
1. Wide Temperature Range
Operates from –60 °C to +120 °C without losing film strength or becoming brittleZhongTian.
2. Mechanical Stability
High-speed bearings and control linkages generate shear stress. Aviation grease resists breakdown, ensuring a stable lubricating film.
3. Moisture Resistance
Aircraft often face humid or wet conditions. This grease repels water, preventing corrosion and washout.
4. Noise Reduction
Its refined formula minimizes gear and bearing noise, enhancing passenger comfort and equipment diagnostics.
5. Extended Service Life
Low volatility and high oxidation stability reduce re-lubrication intervals and maintenance downtime.
