Product Overview

This grease is formulated with a semi-synthetic oil thickened with complex soap, enhanced with extreme pressure (EP), anti-oxidation, and anti-rust additives. Compared with standard lithium-based greases, it offers higher operating temperature, longer service life, and superior anti-wear performance under micro-motion, designed for medium-to-heavy load and high-temperature applications.

Key Features

  • Excellent Extreme Pressure & Anti-Wear Performance: Maximum non-seizure load PB = 1236 N; total wear value ZMZ = 699, effectively protecting medium-to-heavy load bearings, gears, and other components.
  • Superior High Temperature Performance: Dropping point > 300°C; evaporation (180°C, 1h) = 1.9%; resistant to flow loss and degradation, suitable for high-temperature baking equipment.
  • Oxidation Stability: Prevents grease degradation at high temperature, extending service intervals and equipment life.
  • Reliable Corrosion & Rust Protection: Passes 45# steel corrosion test; protects metal components in humid environments.
  • Good Low Temperature Flow: Apparent viscosity (-20°C, 10 s⁻¹) = 1084; maintains lubrication and ensures smooth startup.
