High-Performance Oil Delivers Superior Lubrication in High-Temperature, High-Load Applications

Duolec Industrial Gear Oil (1601-1610, 1302, 1304) is a high-performance industrial gear oil with ISO grades ranging from ISO VG 46 to 1500. Designed for use in any industrial gear or bearing application that requires a thermally stable, extreme pressure/antiscuff lubricant, it maintains performance even after filtration.

Duolec Industrial Gear Oil contains Duolec, LE’s dual acting additive thatmore

Benefits and Recommendations

Available Container Size

2,100 lb Disposable Tank

Typical Applications

  • Enclosed gearboxes
  • Bowl mills / pulverizers
  • Homogenizers
  • Planetary gears
  • Oil lubricated bearings

Beneficial Qualities

Maintains Performance in Extreme Conditions
  • Possesses high film strength
  • Remains stable despite high temps
  • Resists oxidation and sludge formation
  • Provides wear-reducing and EP/antiscuff protection
Adheres to Metal
  • Contains shear-stable tackifier that allows oil to adhere to metal components
  • Remains tacky during high shear use
Resists Moisture
  • Separates readily from water, continuing to provide effective lubrication
    • Ordinary gear oils will emulsify and foam, causing increased friction and poor lubrication
Filterable
  • Contains no solids that can be removed during filtration
  • Remains within viscosity grade after filtration

Performance Requirements Met or Exceeded

  • ANSI/AGMA 9005-F16
  • AIST 224 (US Steel 224)
  • DIN 51517-3 CLP
  • ISO 12925-1 CKD
  • USDA H2

Proprietary Additives

LE’s proprietary additives are used exclusively in LE lubricants. Duolec® Vari-Purpose Gear Lubricant contains Duolec.

Duolec® dual-acting additive imparts synergistic properties to lubricants, providing both wear-reducing and extreme pressure protection. The result of revolutionary technology designed specifically for use in LE gear lubricants, Duolec increases oil film strength and is temperature activated to provide a protective layer that smooths metal surfaces and minimizes the effects of any contact, thereby reducing friction and preventing surface wear.
