Engineered to deliver ultimate wear protection, high viscosity stability, and enhanced performance across transport and industrial fleets.
Delivering high-tech manufacturing capacity and precise formulation control to global heavy-duty markets.
Modern gearboxes operate under increasingly harsh conditions: higher torque densities, compact structural designs, and extreme operational temperature ranges. In high-demand settings like wind turbine main gearboxes, heavy steel mills, and transit drive axles, lubricants are subject to intense shear force and heat. These conditions trigger micro-pitting, oxidative breakdown, and premature component fatigue.
As a leading Chinese gear oil lubricant manufacturer, Shandong Longhai Lubrication Technology Development Co., Ltd. continuously monitors these key global shifts:
International procurement departments face several challenges when choosing a long-term lubricant manufacturer in China. It is not just a matter of price; operators look for partners who can guarantee reliability, consistency, and compliance:
Purchasing managers look beyond the initial purchase price, focusing on how a lubricant helps prevent micro-cracks, extends equipment life, and cuts down on maintenance costs.
B2B buyers require formulations certified to international standards, including DIN 51517 Part III (CLP), US Steel 224, AGMA 9005-E02, and specific OEM approvals such as Mercedes Benz.
Established in 2009 and headquartered in Zibo, Shandong, Shandong Longhai Lubrication Technology Development Co., Ltd. is a high-tech enterprise integrating R&D, production, and sales. For over 15 years, we have been deeply involved in the lubricant industry, building a comprehensive industrial supply chain to serve the global industrial and transport sectors.
Longhai Technology manufactures its proprietary brand "Century Longhai" alongside our international strategic partner brand, the British "A Ba" series. Our wide product portfolio includes diesel engine oil, gasoline engine oil, gear oil, hydraulic transmission oil, anti-wear hydraulic oil, special engineering machinery engine oil, natural gas engine oil, fully synthetic oil, automotive urea solutions, antifreeze, motorcycle engine oil, industrial gear oil, and automatic transmission fluids.
To ensure customer peace of mind, all products are fully insured by PICC China People's Insurance Company, backed by comprehensive liability and quality guarantees.
Our 131-acre production base features an annual output capacity of 200,000 tons, supported by intelligent, fully automated production lines. Our blending facilities use metered-filling systems to guarantee high levels of accuracy and process efficiency:
Custom formulations designed to protect equipment and optimize performance in extreme conditions.
Our L-CKC and L-CKD industrial gear oils are formulated with sulfur-phosphorus extreme pressure additives. They prevent gear surface scuffing and micro-pitting in heavy equipment, such as mining drives, cement mills, and steel mill rolling gearboxes.
Designed for heavy trucks and buses, our API GL-5 and MT-1 gear lubricants provide excellent shear stability. They maintain a reliable protective film under high shock loads, helping to extend the service life of final drives and differentials.
Our premium anti-wear hydraulic fluids are designed to resist thermal breakdown and oxidation. They protect high-pressure hydraulic pumps, reduce deposit formation, and ensure smooth servo-valve operation in manufacturing machinery.
Tailored formulations designed to meet your specific regional regulations, performance requirements, and branding standards.
We formulate semi-synthetic and fully synthetic gear oils and lubricants engineered to your exact performance standards. We adjust viscosity profiles, pour points, and add specialized additives to meet API, ACEA, AGMA, and DIN specifications, making sure the product performs well in your specific target climate and operating environment.
Whether you need extreme low-temperature fluidity for wind turbines in cold climates or high thermal stability for tropical industrial gearboxes, our engineering team can formulate the exact solution you need.
To ensure quality and reliability for our international partners, Longhai Technology operates under strict quality management frameworks. We have obtained core certifications that verify our commitment to clean, safe, and high-performing production processes:
All finished batches undergo strict testing in our laboratory using ASTM and DIN standards, ensuring they perform reliably in demanding field conditions.
