Engineered to deliver ultimate hydrodynamic performance and maximum system protection under extreme operational loads.
Navigating thermodynamic strains, strict carbon regulations, and equipment lifetime optimization in modern manufacturing.
Modern air compressor units account for up to 10% of global industrial electricity usage. Our high-efficiency synthetic formulations minimize boundary friction losses, reducing industrial power draw by up to 4.5% compared to conventional lubricants.
From cryogenic processing facilities in sub-zero regions to metallurgy plants operating in tropical climates, lubricants must maintain viscosity indexes above 150 to prevent thermal breakdown, component shearing, and severe varnish buildup.
Stricter global chemical registrations (such as EU REACH, USA TSCA, and China IECSC) require advanced industrial lubricants to offer biodegradability and minimized heavy metal footprints, ensuring complete environmental and workplace safety.
Shandong Longhai Lubrication Technology Development Co., Ltd., established in 2009 and headquartered in the industrial hub of Zibo, Shandong, is a premier high-tech enterprise integrating scientific research, product development, large-scale production, and global export channels. Spanning over 15 years of industry excellence, we have established a highly specialized and vertically integrated industrial chain model.
We take pride in our flagship domestic brand, "Century Longhai", alongside our strategic international cooperation brand, the British "A Ba" series. Our comprehensive product portfolio is formulated to meet strict global specifications. Our lines feature diesel engine oils (API CK-4 to CF-4), premium gasoline engine oils (API SP, SN, SL, SJ), advanced industrial gear oils (L-CKC/L-CKD), anti-wear hydraulic fluids, specialized transmission oils, motorcycle lubricants, and high-efficiency air compressor fluids. Every batch is fully backed and insured by PICC (People's Insurance Company of China) for absolute quality assurance and client peace of mind.
Sustained R&D investments, automated blending lines, and robust logistical operations that empower global enterprises.
Our blending and filling plant utilizes high-precision automated flow meters, guaranteeing an filling tolerance of 1‰ to 2‰. By integrating closed-loop control systems, filling speeds are optimized by 20% to 35% over legacy setups. This ensures high-throughput output capacity, stable viscosity control, and reliable product purity from base stocks to retail packaging.
Collaborating with top material-science research institutes and key universities, Shandong Longhai houses state-of-the-art laboratory testing. We perform continuous kinematic viscosity tests, ASTM D92 flash point evaluations, oil shear stability measurements, and copper strip corrosion checks to maintain international standards across all operational parameters.
Strict quality control processes verified by global certification bodies to guarantee consistent industrial performance.
To ensure high compliance standards, Shandong Longhai operates under a rigorous triple management system: ISO-9001-2015 (Quality Management System), ISO-14001-2015 (Environmental Management System), and ISO-45001-2018 / 18001 (Occupational Health and Safety Management System).
Our heavy-duty products hold notable international approvals, including official Mercedes-Benz (MB) certifications for automatic transmissions and commercial fleet applications. These certifications provide global procurement directors with verified proof of premium quality and component safety under extreme heat, heavy shear stress, and extended drain intervals.















The molecular engineering behind premium air compressor fluids and industrial gear oils.
In rotary screw and reciprocating compressors, lubricants must form a highly stable seal between the high-pressure screws or pistons. Traditional oils suffer from mechanical shear stress, reducing viscosity at the contact zones and leading to metallic friction. Longhai's synthetic blends contain shear-stable viscosity index improvers that maintain the lubricant film even at operational temperatures exceeding 110°C, minimizing energy draw and component wear.
Additionally, our lubricants are formulated with specialized metal deactivators and rust inhibitors, preventing moisture from corroding key internal compressor surfaces, even when operating in humid coastal or offshore environments.
Oxidation is the primary cause of oil breakdown, leading to carbon deposits, sludge, and varnish. These contaminants clog filtration systems, coat heat exchangers, and trigger emergency thermal shut-downs. By utilizing premium Group II and Group III synthetic base stocks blended with advanced hindered phenol and diphenylamine anti-oxidants, Century Longhai lubricants resist thermal-oxidative degradation.
This allows for significantly longer service life—increasing standard mineral-oil drain intervals from 2,000 hours to over 4,000–8,000 hours in synthetic oil installations, keeping your operations online and lowering overall maintenance overhead.
Tailoring oil formulations, technical specs, and packaging to meet your precise brand requirements and market goals.
Our OEM/ODM services cover everything from base oil selection to custom additive packages (anti-wear, anti-foaming, extreme pressure), designed for specific equipment specifications and diverse climate conditions. We support small-scale trial runs through to bulk international shipments. With our in-house lab validation and quick-turnaround production lines, we help you bring premium quality lubricants to your market under your own brand.
A systematic workflow designed to ensure smooth, efficient, and quality-controlled international operations.

How our custom-tailored industrial lubricants support diverse operational environments worldwide.
In heavy steel rolling mills, gear assemblies and hydraulic lines are subjected to immense shock loads and extreme temperatures. Our high-viscosity-index industrial gear oils (such as L-CKD) are formulated to prevent gear teeth micropitting, reduce foaming, and separate quickly from water contamination, keeping critical production machinery running without interruption.
Excavation systems operate under dust-heavy and highly abrasive conditions. Here, engine and hydraulic oils are vulnerable to soot load buildup and chemical oxidation. Our heavy-duty diesel engine oils (such as CH-4 and CI-4 PLUS) feature robust dispersant chemistry that holds particulate soot in suspension, preventing oil thickening and protecting engine components from premature wear.
Chemical processing relies heavily on continuous gas compressors, where the process gases can dissolve into the oil, reducing its viscosity and leading to mechanical failure. Longhai designs synthetic polyglycol and PAO-based oils that resist chemical washout and dilution, ensuring stable film thickness and maintaining gas compression efficiency.
