Explore our certified range of industrial greases, gear systems lubricants, and heavy-duty motor oils designed to maximize thermodynamic efficiency and structural protection.
Established in 2009 and headquartered in Zibo, Shandong, Shandong Longhai Lubrication Technology Development Co., Ltd. has spent over 15 years developing high-precision lubrication systems for the world's most demanding physical environments. As a trusted Offshore Petroleum Manufacturer and industrial partner, we engineer custom formulations designed to survive critical deepwater pressures, heavy industrial stresses, and intense thermal ranges.
Operating under our signature proprietary brand "Century Longhai" alongside the internationally renowned British "A Ba" series, our product landscape extends from precision industrial hydraulic formulations to marine-grade turbine solutions. Backed by extensive quality coverage from PICC (China People's Insurance Company), we build redundancy and safety into every mechanical system we touch.
Understanding the critical shift in subsea lubrication mechanics, ecological compliance, and structural asset reliability.
Strict adherence to international environmental protocols (VGP compliance) is steering global procurement towards bio-degradable, low-toxicity hydraulic formulations that perform under extreme pressures without threatening fragile marine ecosystems.
With capital investments reaching record levels, oil and gas drillers prioritize high-performance base stocks to extend asset operation spans. Modern solutions must prevent cavitation and oxidation inside deepwater equipment.
Exploration of deeper geological layers exposes lubrication systems to intense hydrothermal variables. Modern formulations must prevent viscosity breakdown at temperatures exceeding 150°C and pressures above 10,000 PSI.
Procuring raw lubricants for heavy maritime operations requires absolute batch-to-batch consistency. The modern global procurement agent seeks specialized, pre-certified compounds that prevent unexpected downtimes on drilling platforms and tankers.
Longhai addresses these micro-requirements by delivering anti-wear hydraulic oils, turbine oils, and air compressor fluids engineered with advanced shear stability. By deploying state-of-the-art additive chemistries, we suppress micro-foaming, eliminate oxidation sludges, and optimize energy transmission ratios in multi-stage power transfer systems.
How our automated manufacturing infrastructure ensures 1‰-2‰ filling precision and rapid international delivery.
At the center of our 131-acre industrial manufacturing campus, Shandong Longhai employs high-capacity digital blending reactors and automated packaging networks. By automating volumetric metering systems, we guarantee high-precision filling tolerances between 1‰ to 2‰, minimizing product giveaway and eliminating external dust contamination risks.
Our intelligent system optimization has successfully increased raw filling speeds by 20% to 35%, giving global distributors and industrial operators the ability to fulfill high-volume orders under compressed turnaround schedules. Every batch undergoes gas chromatography testing, microscopic wear verification, and thermal cycle testing inside our precision chemical laboratories.
Custom chemical formulations designed specifically for private labeling, extreme operating temperatures, and unique industrial equipment requirements.

In heavy marine exploration, quality failure translates directly to massive financial and environmental liabilities. Shandong Longhai mitigates risk by operating under rigid management guidelines. Our facilities maintain certified compliance with ISO 9001:2015 (Quality Management), ISO 14001:2015 (Environmental Management), and ISO 45001/18001 (Occupational Health & Safety).
Additionally, our high-performance transmission fluids hold formal Mercedes-Benz certifications, demonstrating our capability to deliver OEM-grade quality that meets strict European engineering criteria. Every production process is documented, tracing back raw base stock inputs to their respective refining locations.






How we are preparing next-generation lubricating fluids to meet global carbon neutrality and automation standards.
Developing carbon-based nanostructured boundary lubricants. These additives self-assemble into microscopic anti-friction protective layers on internal gears, lowering component temperatures and reducing parasitic power losses by up to 4%.
Formulating advanced polyol esters derived from sustainable sources. These fluids deliver rapid bio-degradation profiles in water environments while matching the oxidative stability of conventional mineral oils.
Connecting lubrication physical status data with machine learning frameworks. By analyzing chemical changes remotely, we help fleet managers run predictive maintenance cycles and extend drain intervals safely.
Addressing the core technical considerations of procurement engineers and drilling superintendents.
