Established in 2009 in the industrial heartland of Zibo, Shandong, Longhai Technology has emerged as a state-of-the-art enterprise specializing in research, formulation development, and global trade of high-tier lubrication products.
Over the past 15 years, our engineering divisions have successfully formulated premium alternatives to top-grade global fluids. By maintaining our domestic hallmark brand "Century Longhai" alongside our strategic international cooperation brand, the British "A Ba" series, we offer comprehensive product lines to world-class OEMs and industrial operators.
To provide our global client base with total peace of mind, all our lubricant grades are fully insured by the People's Insurance Company of China (PICC), guaranteeing comprehensive quality protection and cross-border commercial liability assurance.
Understanding the chemistry, specification alignment, and cost-benefit paradigms of modern driveline procurement.
Modern heavy equipment demands multi-grade performance (e.g., SAE 75W-90, 80W-90, 85W-140). Our formulations align with ASTM D445 standards, keeping kinematic viscosity stable under temperature spikes of over 150°C and maintaining low flow resistance at sub-zero temperatures.
By utilizing high-dose Sulfur-Phosphorus Extreme Pressure (EP) additives alongside localized friction modifiers, our gear lubricants effectively prevent micro-pitting and scuffing on heavily loaded hypoid gears, echoing premium performance baselines.
Operational environments involving marine transit or humid excavation require gear oils with high demulsibility and rapid air-release properties. Our custom blends restrict air entrainment, preventing oil film collapse and component oxidation.

Adapting tribological engineering to support high-efficiency, low-carbon mechanical operations across global industries.
Friction-related energy loss in long-haul fleets represents a significant cost factor. Longhai's high-performance synthetic gear oils are designed to extend oil drain intervals (ODI) up to 100,000 miles. By maintaining a stable, low-friction fluid film across a wider thermal spectrum, fleet operators minimize fuel consumption and transmission failure rates.
Continuous steel casting and rock crushing machinery generate massive shock loads and particulate contamination. Our worm and industrial gear oils employ advanced organo-metallic additives. These chemicals bond directly to metal surfaces, providing sacrificial wear layers that absorb high impact stresses without compromising oil stability.
Wind turbine gearboxes are subjected to rapid wind velocity changes, which can lead to micro-pitting. Our L-CKD heavy-duty gear oils are specifically engineered with micro-pitting resistance. This prolongs component lifespan and minimizes costly offshore or high-altitude turbine maintenance operations.
As global environmental standards tighten, Longhai Technology's R&D department (which receives an annual investment of over 5% of our revenue) focuses on three key future initiatives:
Uncompromising quality control is essential to ensuring batch reliability in global trade.
Our company is fully certified under the ISO 9001-2015 Quality Management System, ISO 14001 Environmental Management System, and OHSAS 18001 Health Management System. We also hold official Mercedes-Benz transmission fluid certification, demonstrating our ability to meet the most demanding European passenger car and commercial vehicle standards.
Operating from our 131-acre manufacturing center, we utilize fully automatic, precision-metered blending and filling lines. Our system delivers a filling accuracy of 1‰-2‰ while increasing packing speeds by 20% to 35% compared to standard systems. This enables us to guarantee short lead times even for large international bulk orders.
Custom formulations tailored to your local environmental conditions, market standards, and equipment specifications.
Whether you require high-viscosity index mineral bases or fully synthetic PAO/ester alternatives, our laboratory customizes formulations to meet API, ACEA, and DIN specifications.
We offer packaging solutions from 1-liter plastic bottles to 200-liter metal drums and intermediate bulk containers (IBC), featuring multi-lingual labeling for global markets.
Every batch undergoes automated laboratory validation, confirming parameters such as Flash Point, Pour Point, Copper Strip Corrosion, and Four-Ball Wear index before dispatch.
We manage customs clearance, safety data sheet (SDS) compliance, and cargo logistics, ensuring hassle-free delivery to destination ports worldwide.
A streamlined, standardized process that ensures transparent verification, manufacturing, and distribution.
We analyze equipment specifications, operating temperatures, and viscosity requirements.
Our laboratory creates custom additive matrices tailored to match or exceed target brands.
We perform third-party testing and dispatch samples to confirm customer specification alignment.
We initiate automated blending, filling, and logistics packing for shipping container transit.
Our technicians provide fluid analysis support and advice on optimizing oil drain intervals.
