- Characteristics: High-temperature polyurea grease, ester oil industrial lubricant, bearing grease, waterproof rust protection grease.

- Base Oil: Formulated with premium ester oil as the base oil, offering outstanding lubricity and thermal stability.
- Thickener: Polyurea thickener provides the grease with a suitable consistency and excellent mechanical stability.
- Additives: Contains specialized additives to deliver superior water resistance and corrosion protection, effectively preventing rust and corrosion in bearings and other components within humid or corrosive environments.
- Viscosity: The kinematic viscosity of the base oil at 40°C is approximately 425 mm²/s, representing a higher viscosity grade. This ensures robust oil film strength under elevated temperatures and heavy loads, guaranteeing effective lubrication.

- High-Temperature Environment Machinery: Well-suited for rolling bearings in applications such as printing machines, electric motors, fans, and clothes dryers. It facilitates lifetime lubrication at temperatures below 150°C, minimizing maintenance expenditures and downtime.
- Specialized Industrial Components: Frequently employed for the lubrication of components like carriers and guide rollers, sprocket hubs, and sealed shielded rolling bearings, demonstrating exceptional performance under high-temperature and heavy-duty operating conditions. It effectively addresses issues like bearing fractures, carbon buildup, grease loss, and seal wear in rotary joints of steam-heated setting machines, as well as rolling bearings in oven motors, fans, and exhaust fans.
- Bearings with Varying Contact Loads: Primarily intended for the lubrication of bearings subjected to point contact loads. It can also be utilized for bearings with linear contact loads and a significant proportion of sliding friction, such as cylindrical roller bearings or tapered roller bearings.
