What Is Great Wall 7019-1 (No.2) EP High Temperature Grease?
Great Wall 7019-1 (No.2) is a No.2 consistency extreme-pressure composite lithium-based high-temperature grease, formulated with semi-synthetic base oil, composite lithium thickener, and compounded with exclusive extreme-pressure, anti-oxidation, anti-rust, and anti-wear functional additives. Complying with Q/SH PRD234-2008 enterprise standards, it features stable colloidal structure, moderate NLGI 2 consistency, and excellent overall performance.
Different from common single lithium greases, this EP grease is professionally optimized for dual working conditions of high temperature and heavy load. It supports a continuous operating temperature range of -30°C to 150°C, with short-term peak temperature resistance up to 180°C. It effectively resists thermal aging and heavy-pressure friction damage, serving as a dedicated lubricant for high-temperature bearings, gears, chains, and coupling transmission parts in heavy industries.
Core Technical Specifications & Product Features
-
NLGI Grade 2 Moderate Consistency Standard No.2 grease density ensures stable adhesion on vertical and high-speed rotating parts, no excessive oil bleeding or dry-out. It adapts to centralized grease filling and manual refueling, suitable for diversified industrial lubrication methods.
-
Ultra-High Dropping Point (Over 300°C) Extremely high dropping point delivers excellent high-temperature resistance. It will not melt, drain, or lose viscosity under long-term 150°C continuous working conditions, maintaining complete lubricating film integrity for high-temperature equipment.
-
Professional EP Extreme-Pressure Performance Built-in extreme-pressure additive system forms a tough anti-friction protective film on metal surfaces. It effectively disperses instantaneous heavy load and impact pressure, preventing metal direct contact, dry friction, and mechanical pitting wear under heavy-duty operation.
-
Excellent High-Temperature Anti-Oxidation Stability The composite formula strongly suppresses thermal oxidation and grease aging. It minimizes carbon residue, varnish, and sludge generation during long-hour high-temperature operation, keeping bearing interiors and transmission components clean and extending relubrication cycles greatly.
-
Wide Temperature Adaptability Maintains good low-temperature fluidity at -30°C, ensuring smooth cold startup of workshop and outdoor industrial equipment without stalling or lubrication failure. It stably adapts to seasonal temperature changes and complex working conditions.
-
Reliable Anti-Rust & Anti-Corrosion Performance Provides effective rust and corrosion protection for metal components in humid, dusty, and high-temperature workshop environments. It isolates oxygen and moisture, reducing equipment corrosion failure during operation and standby periods.
Key Engineering Advantages for Heavy Industry
-
Solves High-Temp Heavy-Load Wear Pain Points Ordinary greases lose extreme-pressure performance at high temperatures, causing severe component wear. 7019-1 No.2 grease retains stable EP lubrication performance under both high heat and heavy load, protecting core transmission parts and reducing equipment failure rate.
-
Reduces Long-Term Maintenance Costs Superior anti-oxidation and anti-aging properties extend grease service life and maintenance intervals. It reduces frequent refueling and component replacement costs, improving industrial production continuity.
-
Stable Shear & Mechanical Stability Resists long-term high-speed shear and mechanical impact. The grease structure will not thin out or fail easily, maintaining consistent lubrication effect for continuous 24/7 industrial operation.
-
Strong Environmental Adaptability Adapts to high-temperature, humid, dusty, and heavy-vibration industrial workshop environments, with excellent comprehensive durability far exceeding ordinary general-purpose greases.
