Established in 2009 and headquartered in Zibo, Shandong, Shandong Longhai Lubrication Technology Development Co., Ltd. stands at the forefront of China's high-tech lubricant research, production, and distribution network. For over 15 years, our enterprise has diligently optimized a complete industrial chain, committing our technical depth to providing advanced, ultra-reliable gear treatment oils and industrial lubrication formulas across global shipping, mining, automotive, and heavy industry sectors.
By leveraging our indigenous core brand "Century Longhai" alongside our highly specialized international collaboration brand, the British "A Ba" series, we present a diversified portfolio engineered to withstand extreme environment demands. The entire range of our formulations, from passenger vehicle motor oils to heavy-duty industrial gear oils, is fully backed by product quality liability insurance from the People's Insurance Company of China (PICC), establishing a foundation of trust and operational reliability for our global client base.
Modern gear treatment oils must do more than form a physical barrier. Longhai’s chemistry utilizes extreme-pressure (EP) additive packages that dynamically react with metal substrates under localized heat, creating a sacrificial nano-tribofilm. This layer prevents metal-to-metal welding and micro-pitting under high-torque, slow-speed conditions.
As the global market transitions toward carbon neutrality, our laboratory is actively developing biodegradable, saturated synthetic ester base-stocks. These lubricants exhibit high flash points, outstanding thermal stability, and natural rapid biodegradability, crucial for offshore wind turbines and marine propulsion gears.
Our future-focused formulas integrate specialized molecular markers compatible with real-time fluid analysis sensors. Operators can track changes in oxidation indices, moisture contamination, and viscosity shifts online, transforming periodic lubricant replacement schedules into a precise predictive-maintenance paradigm.
Operating a modernized, 131-acre manufacturing center, Longhai combines scale with high operational intelligence. By investing over 5% of annual revenue into scientific research and development, our facility integrates fully automated blending systems that guarantee high batch-to-batch repeatability and formulation precision.
Our automated production lines employ weight-based metering systems. This secures a filling accuracy variance of just 1‰ to 2‰. In parallel, it elevates process efficiency, increasing automated packaging output by 20% to 35% over legacy blending configurations.
Equipped with ASTM-standard testing equipment (including gas chromatography, ICP metals emission, and high-frequency reciprocating rig wear testers), our laboratory certifies each production run against rigorous international standards before dispatch.
We source premium mineral base stocks and advanced synthetic PAO polymers globally. Strategic raw material stockpiling allows us to mitigate logistics delays and commodity price volatility, ensuring reliable, on-time deliveries to our global buyers.
Industrial drivetrains face challenging operational conditions depending on their environment. Our tailored lubrication solutions deliver optimized performance, long component lifespans, and minimal equipment downtime.
Gears in ball mills, rotary kilns, and crushers endure heavy shock loads and highly abrasive dust. Longhai’s gear treatment oils are formulated with high-viscosity-index base fluids and high concentrations of extreme-pressure additives. This structure absorbs severe mechanical shock, seals boundary contacts, and repels micro-particulate wear.
Wind turbine gearboxes operate under variable loads in remote, cold, or offshore areas. Our high-performance fully synthetic formulations offer exceptional low-temperature fluidity alongside high shear stability. They prevent micro-pitting, reduce internal friction, and protect the system against moisture-induced corrosion.
Constant exposure to humidity and saltwater calls for robust emulsification resistance. Longhai formulations separate cleanly from water, preventing the formation of corrosive emulsions. They safeguard critical gear surfaces and bearings even in damp marine environments.
We believe quality is the core of our business. Shandong Longhai Lubrication has established a rigorous quality management system to ensure our products meet or exceed global industrial requirements. Our facilities operate under three primary management certifications:
Additionally, our automatic transmission lubricants carry formal approval from Mercedes-Benz, validating their compatibility and shear-protection capabilities in demanding gear applications.
We deliver custom chemical formulations and packaging solutions to support and scale global lubricant brands.
Our lab develops fully synthetic and semi-synthetic lubricant formulations customized to specific equipment demands, local climates, and market positioning. Every formula complies with API, ACEA, and relevant ISO/DIN standards.
