High-Performance Synthetic Oil Provides Reliable, Long-Lasting Protection for Heavily Loaded Gearboxes


Duolec® Syn Gear Lubricant is formulated with 100 percent synthetic base fluid to ensure excellent high- and low-temperature performance. The synthetic base fluid also provides oxidation stability, which contributes to long lubricant life and a reduction in costly lubricant changeovers.


Duolec Syn Gear Lubricant provides uninterrupted operation and long service life for expensive gear applications, including heavily loaded gearboxes that are exposed to temperature extremes. With its special blend of clean gear technology additives, Duolec Syn Gear Lubricant works to prevent deposit formations in high-temperature applications and will not break down over time. The lubricant also provides exceptional low temperature flow properties, protecting gears during the coldest startups.


Featuring Duolec®, LE’s proprietary additive that reduces friction and increases oil film strength, Duolec Syn Gear Lubricant is able to withstand incredible loads and stresses from heavy-duty applications such as pulverizer gear units.

Proprietary Additive

 N/A LE’s proprietary additives are used exclusively in LE lubricants. Duolec® Syn 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.
