Expanded Technical Insights

Our Heavy-Duty Gear Oil is formulated with synthetic base oils and high-performance additives to meet the rigorous demands of modern machinery. Its shear-stable viscosity index improvers ensure consistent lubrication across a broad temperature spectrum, while its advanced EP additives react chemically with metal surfaces under extreme pressure to form a sacrificial protective layer. This layer prevents welding and scoring, even in high-stress applications such as rock-crushing or heavy hauling.

Independent laboratory tests confirm a 40% reduction in wear compared to conventional gear oils, translating to longer component life and lower total cost of ownership. The oil’s low-friction properties also contribute to energy savings, making it an eco-conscious choice for fleet operators.

For applications involving wet brakes or hydraulic systems, consult our technical team for compatibility guidance.

Environmental & Safety Compliance

Biodegradable Additives: Minimize environmental impact in case of leaks.
Non-Toxic Formulation: Safe for use in ecologically sensitive areas.
RoHS and REACH Compliant: Free from hazardous heavy metals.
