Provides Exceptional Gear Protection without EP Additive

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.

 N/A

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
