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 contemporary industrial ecosystem, heavy-duty machinery, wind turbines, mining conveyors, and automotive gearboxes operate under increasingly severe conditions—characterized by high micro-pitting, extreme shock loads, and elevated thermal stress. Leading gear lubricant oils serve as the lifeblood of these mechanical systems, preventing direct metal-to-metal contact, reducing frictional drag, and dissipating operational heat.
Global procurement managers and tier-1 distributors constantly search for dependable suppliers capable of delivering ISO-certified, high-performance formulations that comply with stringent international specifications (such as AGMA, DIN 51517 Part 3, and US Steel 224). The market demand for synthetic gear oils and specialized industrial lubricants is expanding rapidly, driven by the global transition toward energy-efficient machinery and extended maintenance intervals.
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.
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.
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 passed ISO-9001-2015 quality system certification, 14001 environmental management system certification, 18001 health management system certification. Automatic transmission Mercedes-Benz certification has laid the foundation for the healthy development of the company and the stability of product quality. The company strictly follows international standards and introduces foreign production processes and testing technologies to ensure that the products can still perform excellently under extreme working conditions, helping customers improve equipment efficiency and reduce maintenance costs.
