Advanced formulated synthetic lubricants and motor oils designed for extreme wear protection and high temperature stability.
Open gears in heavy machinery, such as rotary cement kilns, ball mills, SAG mills, and coal pulverizers, are subject to some of the most aggressive working environments. Unlike enclosed gear systems that operate within oil baths or oil circulations, open gears run in boundary or mixed lubrication regimes under extremely slow sliding speeds, massive dynamic shocks, and continuous exposure to particulates (clinker, coal dust, mineral slurry).
Proper lubrication is critical to prevent abrasive wear, pitting, spalling, and scuffing. Our specialized open gear lubricants are engineered with premium synthetic base fluids (including polyalphaolefins and esters), high-viscosity index mineral stocks, and a unique additive matrix containing organic polymers, extreme pressure (EP) agents, and solid lubricants like molybdenum disulfide (MoS2) and high-purity graphite.
Established in 2009 and headquartered in the historic industrial hub of Zibo, Shandong, Shandong Longhai Lubrication Technology Development Co., Ltd. is a high-tech enterprise integrating R&D, advanced production, and international logistics. For over 15 years, we have built a complete industrial chain system dedicated to offering robust, highly optimized lubrication solutions for global industrial and transport operations.
As a reliable lubricants manufacturer, Longhai Technology operates our proprietary brand "Century Longhai" alongside international strategic partnerships, including the British "A Ba" series. Our portfolio spans diesel engine oil, gasoline engine oil, gear oil, hydraulic transmission oil, anti-wear hydraulic oil, special engine oil for engineering machinery, natural gas engine oil, full synthetic oil, automotive urea, antifreeze, motorcycle oil, and heavy industrial specialty lubricants.
To ensure global client trust, our brand is fully insured by the PICC (People's Insurance Company of China), providing comprehensive quality liability assurance for all operational machinery.
How our Zibo manufacturing base guarantees international quality and high supply speed.
Equipped with computerized batching and weight-controlled inline blending units, we eliminate manual error. Viscosity variation is strictly maintained within ±0.5% of the control center limit.
Our fully automatic filling lines utilize highly responsive electromagnetic flow meters. Ensuring 1‰ to 2‰ high accuracy while increasing overall packing speeds by 20% to 35% over traditional machinery.
Collaborating closely with leading research universities, our labs house ICP-OES elemental analyzers, rotary viscometers, FZG test stands, and thermal stability analyzers to continuous optimize our products.
Zibo is a core petrochemical powerhouse in China. This proximity to raw base oil supply streams—including Group II hydrocracked base oils, Group III synthetic isoparaffins, and major additive manufacturers—ensures Shandong Longhai has direct pipeline and secure domestic transport access. We lower raw material transport overheads and extend these cost savings to our global partners without compromising technical specifications.
Longhai Technology has constructed a rigorous Quality Management Matrix. We have successfully passed the international standards ISO 9001:2015 quality system certification, ISO 14001:2015 environmental management system certification, and ISO 45001:2018 / 18001 occupational health and safety management system certification.
In addition, our transmission oils have secured OEM approvals, including Mercedes-Benz certifications, ensuring full structural compliance with demanding drivetrain and transmission requirements globally. Every batch of lubricants produced undergoes strict ASTM testing protocols prior to shipping.
Deep customized solutions for heavy engineering industries where standard lubricants fail.
Ore processing mills (SAG & Ball mills) operate continuously under high vibration and high levels of dust contamination. Our open gear greases form a tough protective film that repels abrasive rock fragments and prevents surface scratching, increasing the operating life of ring gears by up to 45%.
Rotary kilns operate under high temperatures, radiating intense heat onto driving open gears. We produce solvent-free, highly adhesive open gear lubricants with superior thermal stability that will not carbonize, drip, or ignite under continuous contact temperatures up to 250°C.
Slewing ring gears on offshore cranes and wind turbines are exposed to salt spray and humidity. Our open gear lubricants incorporate strong rust inhibitors and water-resistant synthetic polymers, resisting wash-off from harsh seawater waves.
From custom chemical formulations to package branding design, we enable rapid go-to-market solutions.
Tailor synthetic and mineral ratios, viscosity parameters, and additive selections (such as food-grade, biodegradable, or graphite-free) to match your local regional climate and machine requirements.
We handle volume production and low-volume pilot test runs. Whether filling small pails (18L), standard drums (200L), or intermediate bulk containers (IBC tanks, 1000L).
We provide chemical safety sheets (MSDS), SGS verification reports, analysis certificates (COA), and third-party laboratory verification for easy customs clearance.
Our packaging support includes design, barcode implementation, multilingual label printing, and global supply logistics directly to your distributor warehouse.
For high-load industrial systems, selecting the appropriate base oil defines operational longevity. Mineral base oils are suitable for stable temperatures, but synthetic Polyalphaolefins (PAO) and Esters offer excellent thermal stability, lower coefficient of friction, and high viscosity index. They maintain protective oil films even at extreme temperatures, helping reduce gear stress and lower overall carbon emissions.
By blending high-molecular-weight polymers, we create lubricants with excellent shear stability and water washout resistance, keeping machinery running smoothly under tough weather conditions.
Our streamlined process ensures your custom lubricants are delivered efficiently.
