Performance of Shell Malleus Grease GL 25

• Exceptional Physical and Mechanical Stability: This grease retains its natural protective properties over its long working life, ensuring consistent performance.
• Excellent Anti-Wear Performance: At working temperatures, speeds, and pressures, Shell Malleus GL 25 forms a protective cushion between large gears (such as girth and bull gears) and pinion teeth.
• Superb Load Carrying Capacity: Thanks to the inclusion of molybdenum disulfide and other solid lubricants, tooth contact zone temperatures are reduced, gear surface pitting is minimized, and stick-slip conditions are alleviated.
• Water Repellent: Shell Malleus GL 25 effectively resists water wash-off, whether by immersion or spray.
• Corrosion Protection: Metal surfaces are shielded from corrosion, even in hostile environments like saltwater conditions.
• Environmental Compliance: Shell Malleus GL 25 is intentionally free from lead and solvents.

Features of Shell Malleus Grease GL 25

• Balanced Formulation: The unique blend of high-quality paraffinic mineral and synthetic base oils ensures pliability over extended periods, preventing lubricant buildup in gear teeth roots.
