Explore our highly engineered industrial and heavy-duty transport formulation catalog. Each batch undergoes rigorous testing to guarantee extreme load and shear resistance.
Established in 2009 and headquartered in the industrial hub of Zibo, Shandong, Shandong Longhai Lubrication Technology Development Co., Ltd. has evolved over 15 years into a leading high-tech enterprise integrating R&D, advanced manufacturing, and global trade. By establishing a robust, vertically integrated supply chain, we deliver premium lubrication solutions tailored to the strict parameters of modern industrial machinery and transcontinental fleets.
Longhai Technology operates with its prominent domestic brand "Century Longhai" alongside the prestigious strategic cooperative brand British "A Ba" series. Our comprehensive catalog ranges from API-certified diesel and gasoline engine oils, hydraulic transmission fluids, high-efficiency turbine and compressor oils, to heavy-duty industrial gear oils, automotive urea solutions, and special formulations for engineering machinery. The absolute reliability of our brand is insured under the comprehensive product liability framework of PICC (China People's Insurance Company), assuring operations managers of maximum asset protection.
Exploring the engineering foundation that makes Longhai Technology a trusted global OEM/ODM manufacturer.
Operating a modernized production complex stretching across 131 acres, our facilities represent the pinnacle of China's Lubrication Factory 4.0 initiative. We have integrated fully automated digital blending manifolds with volumetric metering technology to assure uncompromising product uniformity. Our filling systems run on high-precision closed-loop controls, keeping filling error tolerances within an exceptional 1‰ to 2‰ margin.
By upgrading our production infrastructure to smart automation, we have boosted overall processing and packaging speeds by 20% to 35%. This technological efficiency ensures high-volume orders are fulfilled rapidly, allowing international distributors to maintain optimal safety stock levels while mitigating raw material price fluctuations. From base oil storage to additive blending, and automated drumming to palletizing, every step is traced under strict digital control systems.
How our custom-tailored formulations combat mechanical degradation, thermal stress, and premature component fatigue.
Our heavy-duty industrial gear oils (L-CKD and extreme-pressure worm gear formulations) incorporate advanced organosulfur-phosphorus additives. This forms a robust boundary lubrication layer that prevents micro-pitting and scuffing in heavy mining gearboxes and steel rolling mills under massive shock loads.
Engineered to resist ash deposition, varnishing, and thermal oxidation, our air compressor oils offer superior moisture separation (demulsibility). This minimizes sludge formation, prolongs filter replacement cycles, and keeps discharge temperatures well within safe thresholds.
Our anti-wear hydraulic oil series is formulated with shear-stable viscosity index improvers. This maintains optimum oil-film thickness even under elevated pressures and temperatures, preventing pump cavitation and ensuring seamless transmission of hydraulic force.
Longhai Technology's R&D department is focused on the next generation of industrial fluids. As industries move toward carbon neutrality, we are actively developing bio-based lubricants with high biodegradability and low environmental impact. Our research team partners with top chemical universities to engineer lubricants that optimize energy transmission and reduce mechanical friction coefficients.
Our upcoming technology roadmap focuses on specialized low-viscosity fluids for Electric Vehicle (EV) drivetrains and advanced thermal management oils for hyperscale data centers. By optimizing molecule structures at the synthetic level, our aim is to extend fluid lifespans, decrease waste oil production, and help our global partners meet their Environmental, Social, and Governance (ESG) targets.
From custom chemical formulations to private labeling, we help global distributors build their own premium brands.
Our commitment to international quality standards is backed by strict certifications and rigorous laboratory testing.
Longhai Technology operates under strict adherence to global quality frameworks. The company has passed ISO-9001-2015 quality system certification, ISO-14001-2015 environmental management system certification, and ISO-45001-2018 occupational health and safety management system certification. Our automatic transmission fluid (ATF) series is certified by Mercedes-Benz, indicating compliance with strict European automotive standards.
Our dedicated Quality Assurance laboratory is equipped with state-of-the-art diagnostic instruments, including Inductively Coupled Plasma (ICP) spectrometers, Cold Cranking Simulators (CCS), and High-Temperature High-Shear (HTHS) testers. This allows us to perform real-time quality control checks on raw materials, base oils, and finished goods before shipment, ensuring consistent batch-to-batch performance.
Understanding critical challenges in bulk oil logistics, import tariffs, compliance documentation, and shelf-life stability.
We reduce TCO by extending oil drain intervals and minimizing wear-related component failures. Our formulations are designed to resist oxidation, keeping operational costs low over time.
We supply products in heavy steel drums, IBC totes, or bulk flexitanks. Our logistical connections to major international ports (including Qingdao Port) ensure reliable and timely global shipping.
We prepare all necessary global transport documentation, including REACH declarations, GHS-compliant safety labels, and SDS sheets in multiple languages for easy customs clearance.

L-CKD heavy-duty gear oils are designed for higher mechanical pressures, higher operating temperatures, and severe operating environments compared to medium-load L-CKC oils. L-CKD contains advanced extreme-pressure (EP) additives that prevent contact micro-pitting in heavily loaded industrial gear systems, such as wind turbine gearboxes, cement mills, and heavy mining machinery.
Yes. We provide complete OEM and ODM services, which include custom additive formulation, base oil selection (Group I, II, III, or PAO synthetic), custom packaging, label printing, and certification support. Our blending lines can be adjusted for small test batches or continuous high-volume production runs.
Our factory uses a smart DCS (Distributed Control System) that automates the weighing and mixing of base oils and additives. By monitoring temperature, viscosity, and flow rates in real time, our filling and blending systems keep tolerances within an exceptional 1‰ to 2‰ range, preventing batch variation.
Our facilities are certified under ISO 9001:2015 (Quality), ISO 14001:2015 (Environment), and ISO 45001:2018 (Occupational Health & Safety). Our transmission products have also received official Mercedes-Benz approvals, meeting European performance standards for automotive drivelines.
Standard order processing and shipping lead times generally range between 15 to 30 days, depending on the volume of the order and configuration requirements. Our proximity to the Port of Qingdao provides reliable ocean freight shipping options to major global industrial hubs.
