Great Wall® 7019-2 Extreme Pressure High-Temperature Grease
Reliable Lubrication for High-Load and High-Temperature Industrial Equipment
Great Wall® 7019-2 Extreme Pressure High-Temperature Grease is a high-performance industrial lubricant specifically developed for equipment operating under high temperatures and heavy loads. It is formulated with deeply refined mineral base oil thickened by a composite metal soap system and enhanced with a carefully balanced additive package including extreme pressure (EP), anti-wear, antioxidant, and rust-preventive agents. This advanced formulation provides stable lubrication performance, strong load-carrying capability, and reliable protection for bearings and friction pairs in demanding operating environments.
The product is designed to accommodate various lubrication methods. NLGI Grade 1 grease is suitable for centralized lubrication systems, while NLGI Grades 2 and 3 are ideal for manual grease application, offering flexibility to meet different equipment requirements and maintenance practices.
Product Overview
Great Wall® 7019-2 is engineered to deliver long-lasting lubrication under conditions where conventional greases may soften, flow away, or degrade rapidly. Its composite metal soap thickener provides excellent thermal stability, allowing the grease to maintain consistency and adhesion at elevated temperatures. The refined mineral oil base ensures adequate oil film strength to support heavy loads while maintaining reliable lubrication over extended service intervals.
By combining high-temperature resistance with strong extreme pressure and anti-wear properties, 7019-2 effectively reduces friction and wear, helping to protect critical components and improve overall equipment reliability.
Key Performance Features
Excellent High-Temperature Resistance
7019-2 demonstrates outstanding resistance to high operating temperatures. Even when friction points are exposed to elevated heat or high ambient temperatures, the grease resists softening and leakage. This ensures that bearings and friction surfaces receive continuous lubrication, effectively extending bearing service life under high-temperature conditions.
Strong Extreme Pressure and Anti-Wear Performance
The grease provides excellent EP and anti-wear characteristics, enabling it to withstand heavy loads and certain impact loads commonly encountered in industrial machinery. It forms a durable protective film that minimizes metal-to-metal contact, reduces surface fatigue, and prevents premature component failure.
Good Oxidation Stability
7019-2 exhibits reliable oxidation stability, preventing grease degradation during prolonged operation. This characteristic ensures a longer usable life of the lubricant, reduces the formation of harmful oxidation by-products, and supports extended relubrication intervals.
Reliable Rust and Corrosion Protection
With effective rust-preventive additives, the grease provides continuous protection for lubricated parts, shielding metal surfaces from corrosion caused by moisture, humidity, or harsh operating environments. This contributes to improved equipment durability and reduced maintenance costs.
Environmentally Responsible Formulation
The product does not contain heavy metals, nitrites, or other substances harmful to human health. Its formulation is designed to avoid introducing new environmental pollution, making it suitable for use in modern industrial operations with higher environmental and safety requirements.
Technical Standard Compliance
Great Wall® 7019-2 Extreme Pressure High-Temperature Grease complies with Q/SH PRD 332-2010, ensuring consistent product quality and performance reliability for industrial applications.
