Almasol® Pure Mineral Gear Lubricant (401) is a balanced formulation of base oil, rust and oxidation inhibitors, wear-reducing agents, and other additives that provides the highest level of protection possible without the inclusion of an extreme pressure additive. When transmission and gearbox manufacturers specify a “pure” or “straight” mineral oil gear oil, it should not contain a chemically active EP agent; other additives, however, are still acceptable for inclusion. In addition to other highly desirable additives, the Almasol 401 formulation contains Almasol, LE’s exclusive wear-reducing additive that protects against premature wear and shields metal against corrosive attack.

Longer Gear Life

• Reduces wear with excellent film strength, lubricity and wear-reducing additives
• Climbs gears immediately at startup, assuring immediate lubrication
• Stays in place, even after equipment remains idle for extended periods
• Reduces operating temperatures over ordinary gear oils

Longer Oil Life

• Withstands elevated temperatures without oxidizing and forming sludge
• Resists formation of rust and corrosive acids that can result from moisture
• Is nonfoaming in service

Lower Operating Costs

• Ensures longer gear and lubricant life
• Reduces downtime
• Reduces expenses for labor and parts
• Does not affect seals
