Shell Malleus Grease GL 300

Description

Product Description

Shell Malleus Grease GL 300 is a premium-quality, lead and solvent-free, full EP lubricant specifically developed for the lubrication and protection of open gears and wire ropes. Whether it’s grinding mills, kilns, shovels, draglines, ship loaders, stackers, or reclaimers, this grease ensures exceptional performance even under extreme ambient temperatures and operating conditions. Let’s dive into the details!

Performance of Shell Malleus Grease GL 300

• Exceptional Physical and Mechanical Stability: Shell Malleus GL 300 retains its natural protective properties over its long working life, ensuring consistent performance.
• Excellent Anti-Wear Performance: At working temperatures, speeds, and pressures, this grease forms a protective cushion between large gear teeth and pinions, reducing wear.
• Superb Load Carrying Capacity: Thanks to the inclusion of molybdenum disulfide and other solid lubricants, it effectively reduces gear surface pitting and alleviates “stick-slip” conditions.
• Water Repellent: Resists water wash-off by immersion or spray.
• Corrosion Protection: Shields metal surfaces from corrosion, even in harsh environments like saltwater conditions.

Features of Shell Malleus Grease GL 300

• Unique Blend of Base Oils: It combines high-quality paraffinic mineral and synthetic base oils with carefully selected additives for optimum performance.
• Balanced Formulation: The balanced formulation keeps the lubricant soft and pliable over extended periods, preventing build-up in gear teeth roots.
• Graphite and MoS2: These solid lubricants enhance separation between heavily loaded gear teeth, creating a durable protective film.

Benefits of Shell Malleus Grease GL 300

• Reduced Maintenance: The grease remains pliable, resisting drying out in gear teeth or shrouds, even in dusty conditions.
• Lower Lubricant Consumption: Its tenacious film allows for reduced application rates compared to traditional fluid-type gear lubricants.
• Environmental Compliance: No intentionally added lead or solvents, reducing environmental concerns.
