Engineered lubricants providing unparalleled oxidation stability, gear wear reduction, and optimized fuel economy across intensive operating limits.
Founded in 2009 and headquartered in the prominent chemical industrial cluster of Zibo, Shandong, Shandong Longhai Lubrication Technology Development Co., Ltd. stands as a premier high-tech enterprise. Our company integrates cutting-edge Research & Development, standardized production, and global sales channels. Over more than 15 years, we have built a complete, resilient industrial chain system dedicated to delivering high-performance lubrication solutions to worldwide industrial and heavy transport sectors.
As a highly reliable manufacturer, Longhai Technology operates its proprietary premium brand "Century Longhai" alongside the international strategic cooperation brand—the British "A Ba" (Abro) series of products. Underwritten by the PICC China People's Insurance Company, our oils come with high-tier quality assurance. Our expansive production capabilities cater to diesel engine oils, gasoline engine oils, gear oils, hydraulic transmission fluids, anti-wear hydraulic fluids, specialized engineering machinery oils, natural gas engine oils, fully synthetic lubricants, automotive urea solutions, antifreeze, motorcycle engine lubricants, and customized industrial gear oils.
Analyzing key drivers in tribological science, shifting industrial constraints, and the strategic positioning of Chinese manufacturing.
Modern industrial gearboxes are experiencing unprecedented torque loads and thermal pressures. Traditional lubricants fail under extreme boundaries, leading to micro-pitting and gear fatigue. Formulations modeled on international standards, such as those within the Abro Gear Oil framework, utilize sulfur-phosphorus extreme pressure additives that chemically react with metal surfaces under friction, forming a resilient sacrificial boundary layer.
Global procurement teams prioritize total cost of ownership (TCO) and ESG metrics. Synthesized hydrocarbon base stocks (PAO) coupled with advanced ester chemistry offer long-drain performance. They possess excellent viscosity indexes, minimizing shear loss over thousands of operating hours and reducing hazardous waste generation.
Industrial components operate in volatile climates, from offshore wind farms to desert mining hubs. Global buyers need high pour-point depression and stellar low-temperature flow rates combined with high-temperature shear resistance. Shandong Longhai's strategic British "A Ba" cooperation addresses these international specifications directly.
Shandong Longhai's Zibo facility leverages Industry 4.0 principles to deliver supply chain resilience. Our fully automatic blending and filling production line integrates metering systems designed to achieve an outstanding filling accuracy of 1‰-2‰. By introducing automated PLC-controlled mass flow systems, we have improved filling speed by 20% to 35% relative to legacy installations, resulting in consistent batch stability and rapid order delivery.
By using premium base oils and high-purity imported additives (Lubrizol, Afton, Infineum), Longhai ensures that each batch of gear and motor oils matches strict European and American engineering requirements. This automated manufacturing architecture prevents cross-contamination, ensuring that products achieve high performance even under harsh environments.
Demonstrating technical excellence, quality consistency, and rigorous environmental compliance under global verification protocols.
Our quality system is verified under three key global management systems: ISO 9001:2015 (Quality Management System), ISO 14001 (Environmental Management System), and ISO 45001 / 18001 (Occupational Health and Safety Management System). Our automatic transmission lubricants have also attained the prestigious Mercedes-Benz Certification.
Through our advanced testing laboratory, we verify every metric—including kinematic viscosity at 40°C and 100°C, viscosity index, flash point, pour point, copper strip corrosion properties, and water separation characteristics (demulsibility). This guarantees that our gear oils and hydraulic oils remain stable in demanding operations.

Our R&D engineers answer critical technical and supply questions from global procurement managers.
A: L-CKC (Medium-Duty) and L-CKD (Heavy-Duty) are distinct industrial gear oil classifications defined by their load-bearing capacity and formulation chemistry. L-CKC is designed for gear systems operating under mild to moderate loads, utilizing anti-wear agents to shield gears. L-CKD, however, is formulated with an advanced extreme pressure (EP) additive package, giving it the load-carrying capacity needed to prevent micro-pitting in high-load gear systems. It also features superior thermal oxidation stability, protecting machinery at temperatures exceeding 100°C.
A: We maintain batch consistency through our automated blending and filling technology. Our 131-acre facility utilizes PLC systems to regulate formulation metrics like heating, mixing, and raw material injection. The mass flow meters on our filling lines ensure accuracy within 1‰ to 2‰, preventing human error. Additionally, we run physical-chemical tests on every batch before packaging, retaining reference samples for future tracking.
A: Under heavy loads, the hydrodynamic oil film between gear teeth can collapse, leading to direct metal-on-metal contact. Sulfur-phosphorus extreme pressure (EP) additives are engineered to solve this. At high temperatures, these compounds react with the metal surface to create a high-strength chemical layer. This sacrificial film shears easily, preventing metal transfer, adhesive wear, and scoring of gear teeth.
A: Buyers should look for three core credentials: first, ISO management certifications (ISO 9001:2015, ISO 14001, and ISO 45001/18001); second, IATF 16949 for automotive supply chains; and third, OEM-specific approvals like our Mercedes-Benz transmission fluid certification. These credentials verify that the factory operates under strict quality, environmental, and safety frameworks. Product liability insurance, such as our coverage from PICC, also provides an additional layer of financial protection.
