Explore our top-performing industrial and automotive formulations, engineered to withstand extreme shear and thermal challenges.
Understanding the molecular dynamics, extreme pressure performance, and fluid film boundaries that protect global machinery.
In modern industrial manufacturing, machinery is continuously subjected to heavier loads, higher operating temperatures, and tighter mechanical tolerances. Under these extreme stresses, conventional lubricants experience severe viscosity breakdown, leading to metal-to-metal contact, accelerated wear, and catastrophic equipment failure. High Viscosity Gear Oils are specifically engineered to address these operational vulnerabilities by maintaining a thick, robust hydrodynamic oil film under high-shear, low-speed, and heavy-torque conditions.
At the core of Shandong Longhai's high viscosity formulations lies a deep understanding of boundary lubrication physics. By selecting premium, high-viscosity index base stocks and marrying them with state-of-the-art additive packages, we ensure that our gear oils resist thermal degradation and shearing forces, providing a secure barrier that prevents micro-pitting, scuffing, and fatigue-induced surface failures.
Developing high viscosity lubricants (such as ISO VG 320, 460, 680, and specialized 1000+ grades) requires precise base oil selection and molecular structure stability:
We are actively researching next-generation solutions to address future industrial challenges:
From deep mining operations to off-shore wind power generators, our high viscosity gear oils keep critical equipment running.
Wind turbine gearboxes operate under high transient forces and harsh environmental fluctuations. Our high viscosity synthetic gear oils resist micropitting, a structural failure common in wind applications, protecting internal gears and extending service intervals in remote offshore sites.
Heavy ball mills, crushers, and excavation shovels function in extremely dusty environments with constant shock loading. Our formulations utilize advanced tackifier chemistry and anti-wear agents to seal out moisture and dust, preventing abrasive wear under the highest loads.
Hot rolling mills demand lubricants that perform reliably at high temperatures and resist water washout from process cooling sprays. Longhai CKC and CKD gear oils are optimized to demulsify rapidly, allowing water separation and continuous, reliable wear protection.
How Shandong Longhai combines massive production scale, quality insurance, and automated logistics to support global customers.
Located in Zibo, Shandong, our state-of-the-art production base covers over 131 acres, housing an annual production capacity of 200,000 tons of high-quality lubricants. Our facilities are equipped with fully automated intelligent blending systems and high-precision laboratories to meet custom requirements.
Our packaging facilities utilize a dynamic volumetric metering system, maintaining an accuracy tolerance of 1‰ to 2‰. This system increases packaging throughput by 20% to 35% compared to standard machinery, ensuring that we meet short lead times and maintain rapid global delivery schedules.
