Great Wall 7029A Urea Grease

High-Temperature, Water-Resistant Grease for Heavy-Duty Industrial Bearings

Great Wall 7029A Urea Grease is a premium industrial lubricating grease formulated with high-quality base oil thickened by an organic urea thickening agent, combined with extreme-pressure, anti-oxidation, anti-corrosion, and rust-inhibiting additives. The product is engineered to deliver long service life, stable lubrication, and reliable protection for bearings operating under high temperature, heavy load, humid, and chemically aggressive environments.

According to consistency grade, 7029A is available in 0#, 1#, 1.5#, and 2#, allowing users to select the most suitable grade for different lubrication methods, including manual lubrication and centralized lubrication systems. The grease complies with Q/SH PRD224-2008 and ZD.221-2005 technical standards.

Excellent Oxidation Stability and High-Temperature Resistance

One of the most significant advantages of Great Wall 7029A is its outstanding oxidation stability, which effectively prevents grease hardening, oil degradation, and deposit formation during prolonged high-temperature operation. With a drop point above 330°C and low evaporation loss (≤1.2% at 150°C for NLGI 2 grade), the grease maintains its structure and lubricating film even under continuous thermal stress.

This performance makes 7029A particularly suitable for steel plant continuous casting lines, rolling equipment, and cement production machinery, where bearings are exposed to sustained high temperatures.

Balanced High- and Low-Temperature Performance

7029A urea grease offers reliable lubrication across a wide operating temperature range, ensuring stable bearing performance from low temperatures to elevated operating conditions. Its low similar viscosity of 893 Pa·s at –10°C (NLGI 2) ensures acceptable start-up torque and smooth bearing operation, while maintaining sufficient film strength at higher temperatures.

This balanced temperature performance allows equipment to operate reliably during seasonal temperature changes or fluctuating process conditions.

Superior Water Resistance and Chemical Stability

The grease demonstrates excellent resistance to water washout, making it highly suitable for wet, humid, or water-splash environments, such as water pump bearings, cooling sections of steel mills, and cement plant equipment exposed to moisture.

In addition, 7029A shows good resistance to acidic gas media, allowing it to perform reliably in environments containing corrosive gases or industrial fumes. This chemical stability significantly extends bearing service life and reduces unplanned downtime.

Good Pumpability and Lubricity

Great Wall 7029A urea grease features good pumpability, even in centralized lubrication systems, ensuring smooth grease delivery without pipeline blockage. This characteristic is especially important in large-scale industrial plants where centralized lubrication is widely used.

Its excellent lubricity and load-carrying capability help form a strong and stable lubricating film, reducing friction and wear in ball bearings, roller bearings, and plain bearings under medium to heavy loads. As a result, bearing wear is minimized, maintenance intervals are extended, and overall operating costs are reduced.

Typical Applications

Great Wall 7029A Urea Grease is designed for long-term lubrication of medium and heavy-duty bearings operating under harsh industrial conditions, including:

• Continuous casting machine bearings in steel mills

• Conveyor roller bearings

• Water pump bearings

• Cement plant bearings and gears exposed to water

• Centralized lubrication systems in metallurgical plants

Recommended operating temperature range: –10°C to +150°C

Multiple steel plants have successfully replaced conventional lithium and aluminum complex greases with 7029A, effectively solving problems such as grease line blockage, rapid grease loss, and insufficient lubrication, resulting in significantly reduced maintenance workload and improved production continuity.
