Explore our top-tier industrial gear oils, heavy-duty diesel engine protection fluids, and high-performance specialized lubrication formulations engineered for extreme conditions.
Shandong Longhai Lubrication Technology Development Co., Ltd. — Pioneering Global Industrial Lubrication Standards Since 2009.
Shandong Longhai Lubrication Technology Development Co., Ltd. was established in 2009 and is headquartered in Zibo, Shandong. It is a high-tech enterprise integrating R&D, production and sales. The company has been deeply involved in the lubricant industry for more than 15 years, has built a complete industrial chain system, and is committed to providing high-quality lubrication solutions for the global industrial and transportation fields.
As a reliable lubricant manufacturer in the industry, Longhai Technology owns its own brand "Century Longhai" and the international strategic cooperation brand British "A Ba" series of products. The products cover diesel engine oil, gasoline engine oil, gear oil, hydraulic transmission oil, anti-wear hydraulic oil, special engine oil for engineering machinery, special oil for natural gas, full synthetic oil, automotive urea solution, antifreeze, special engine oil for motorcycles, industrial oil, automatic transmission oil and many other lubricant varieties. The brand is insured by PICC China People's Insurance Company and quality insurance.
In the modern macroeconomic environment, heavy-duty industries, maritime shipping, and wind power generation require supreme gear lubrication to minimize friction losses and thermal breakdown. Gear lubricants operate under extreme boundary lubrication regimes where micro-asperities experience high contact pressures.
Our advanced formulations incorporate sulfur-phosphorus Extreme Pressure (EP) additives that chemically bond with metal surfaces, preventing scuffing, micropitting, and catastrophic gear tooth failure. By optimizing viscosity-temperature profiles, Longhai industrial gear oils extend equipment overhaul intervals by up to 40%.
Driven by innovation, precision engineering, and rigorous quality control systems.
Longhai Technology has always insisted on innovation-driven development. Its annual R&D investment accounts for more than 5% of its annual revenue. It has established strategic cooperation with many universities and scientific research institutions to continuously optimize lubrication technology and promote industry progress. At present, the company's production base covers an area of 131 acres, with an annual production capacity of 200,000 tons. It is equipped with intelligent production lines and precision laboratories to meet the customized needs of different customers.
In terms of market layout, Longhai Technology has built a sales network covering the whole country. Its products are sold well in 139 cities in 29 provinces, autonomous regions, municipalities and special administrative regions, and are exported to overseas markets, winning the trust of many leading companies in the industry.
The company has advanced blending and fully automatic production and filling equipment. The filling production line adopts the principle of metering filling, which is suitable for filling various lubricating oils and ensures the filling accuracy of 1‰-2‰. While ensuring the filling accuracy, it increases the filling speed by 20%-35%, effectively increases the work efficiency, and realizes the standardized production of the enterprise. It guarantees the delivery speed and quality of our company to a great extent.
Meeting rigorous global compliance standards with tailored industrial application strategies.
Our R&D roadmap focuses on biodegradable synthetic base fluids, graphene-enhanced anti-wear nanotech, and energy-efficient low-viscosity gear oils. As wind turbines and robotics demand higher torque density, Longhai anticipates future lubrication requirements by developing nano-lubricants capable of self-healing micro-surfaces under extreme thermal stress.
We maintain strict adherence to ISO 9001:2015 quality systems, ISO 14001 environmental standards, and OHSAS 18001 health management. Furthermore, our automatic transmission formulations hold official Mercedes-Benz certifications, ensuring seamless compliance across global regulatory jurisdictions.
