Explore our leading range of high-performance automotive and industrial lubricants manufactured to strict international standards.
Shandong Longhai Lubrication Technology Development Co., Ltd. is a high-tech enterprise integrating R&D, production, and global sales. For over 15 years, we have built a complete industrial chain dedicated to delivering high-performance lubrication solutions for industrial machinery, heavy transportation, wind energy, and automotive industries worldwide.
Headquartered in Zibo, Shandong, our brand "Century Longhai" along with our international strategic brand British "A Ba" series have gained recognition for engineering lubricants that exceed standard specifications. Our product portfolio is comprehensively insured by the People's Insurance Company of China (PICC), providing our global buyers with total commercial confidence.
Analyzing key drivers reshaping the global synthetic gear oil and industrial lubricants landscape.
Modern industrial gearboxes operate under increasingly compact designs and higher load densities. Synthetic gear oils formulate with high-purity Polyalphaolefins (PAO) and synthetic esters to prevent viscosity breakdown under intense mechanical stress and extreme operating temperatures.
Due to lower internal friction and improved traction coefficients compared to traditional mineral alternatives, advanced synthetics minimize viscous drag. This reduction optimizes power transfer efficiency, lowers overall operating temperatures, and aligns with corporate ESG targets.
By resisting oxidation and thermal degradation, synthetic gear oils maintain their physical properties up to four times longer than mineral oils. This reduces oil changes, minimizes system downtime, and lowers the Total Cost of Ownership (TCO) across complex machinery layouts.
Solving the supply-chain bottlenecks of large-scale procurement agencies, plant managers, and distribution networks.
Procuring lubricants at a global scale requires absolute consistency, certified quality parameters, and structured logistics. Large manufacturers look for suppliers that can deliver standardized formulations across multiple facilities while maintaining stable chemical margins.
Shandong Longhai Lubrication addresses these critical procurement needs through:



How our heavy-duty synthetic gear oils and fluids prevent premature wear across intensive industrial environments.
Wind turbine main gearboxes operate under constant speed variations, shock loads, and high moisture exposures. Our synthetic PAO lubricants offer advanced protection against micropitting, reducing maintenance call-outs in offshore and remote locations.
Operating under fine particulate contaminants and extreme loads, crusher gears and steel rolling mills depend on highly robust extreme-pressure (EP) additive chemistry. Our formulation shields tooth surfaces from scuffing, ensuring high uptime.
Exposure to saltwater raises the risk of corrosion and oil emulsification. Longhai synthetic gear oils utilize advanced demulsibility agents, rapidly shedding water to preserve the load-bearing hydrodynamic oil film.
Underpinned by comprehensive international accreditations ensuring safety, consistency, and engine manufacturer approvals.
Our Zibo production complex is managed under strict international framework standards to meet standard global import compliance. Our certifications include:
These credentials ensure that each shipment meets technical specifications under extreme working parameters, helping commercial operators lower wear risk.









From initial design to global delivery: how we configure custom formulation pipelines.
We analyze the customer’s local operating environments, OEM parameters, target pricing, and viscosity index profiles.
Our laboratory designs custom synthetic bases (PAO, Ester, PAG) paired with premium additive configurations.
We perform rigorous bench tests (including FZG wear testing, four-ball wear scar, and kinematic viscosity assessments).
Utilizing high-speed automated filling lines, we run batches at 1‰-2‰ volumetric accuracy.
We prepare export documentations, sea freight packaging, and direct customs clearing support.
How we integrate sustainable tribology research to align with future industrial machinery designs.
The transition toward electrification, higher power density, and reduced environmental impact requires continuous research. Longhai's engineering team focuses on three key future initiatives:
Expert insights on key tribology questions concerning synthetic gear oils and industrial fluids.
Polyalphaolefins (PAO) synthetic base oils feature a highly uniform chemical structure, lacking the wax components found in mineral alternatives. This structure provides a significantly higher viscosity index (stable performance across temperature shifts), lower pour points for cold operations (-40°C or below), and superior oxidation stability. This extends service lifetimes up to 300% to 400% compared to mineral lubricants.
Micropitting is a type of surface fatigue occurring on gear teeth surfaces, often leading to tooth wear and failure. Our L-CKD industrial gear oils are formulated with advanced extreme-pressure (EP) additives that create a sacrificial chemical film at contact points. This film absorbs extreme loading energy, minimizing micro-cracking and protecting high-precision gearing systems under heavy stress.
Generally, PAO (Polyalphaolefin) and PAG (Polyalkylene Glycol) synthetic lubricants are chemically incompatible. Mixing them will result in fluid separation, viscosity changes, and loss of critical lubrication properties. When switching a system between these bases, a thorough flushing process is required to ensure system reliability.
Each product batch undergoes inspection in our on-site precision laboratory before packaging and dispatch. We test kinematic viscosity (at 40°C and 100°C), viscosity index, pour point, water content, and copper strip corrosion. All procedures follow ASTM and ISO standards, and each shipment is accompanied by a comprehensive Certificate of Analysis (COA) for full traceability.
