Engineered to deliver exceptional thermal stability, shear resistance, and structural wear protection under severe operational environments.
Analyzing tribological demand profiles, structural efficiency requirements, and molecular performance factors shaping modern industrial operations.
In the era of high-precision heavy machinery and deep decarbonization mandates, the global industrial sector faces an unprecedented tribological challenge. Lubrication is no longer merely a maintenance overhead; it is a critical vector for mechanical integrity, energy conservation, and system lifecycle extensions. Across mining, metal processing, automated manufacturing, and logistics networks, the mechanical interfaces operate under tighter tolerances, higher thermal gradients, and heavier loads.
Friction accounts for approximately 20% of global primary energy consumption. High-performance synthetics minimize boundary-friction energy losses, contributing to direct electrical and fuel conservation in large-scale rotating equipment.
Heavy duty applications call for extreme pressure (EP) additives that chemically react with metal surfaces to build high-strength boundary films, protecting critical gear teeth against micro-pitting under high shock loads.
Modern synthetic oils exhibit high oxidation stability, resisting the creation of sludge and corrosive acids. This allows plants to extend drain intervals up to 4x compared to conventional API Group I/II mineral oils.
"The strategic alignment between mechanical design and tribological chemistry determines the productivity limits of heavy manufacturing. Formulations must be customized at a molecular level to handle localized environmental pressures, including moisture, extreme temperatures, and chemical exposure."
Established in 2009 and headquartered in Zibo, Shandong, Shandong Longhai Lubrication Technology Development Co., Ltd. is a premier high-tech enterprise integrating research and development, manufacturing, and global exportation. Over the course of 15 years, Longhai has established an integrated supply chain system, delivering tailored lubrication solutions across automotive, marine, aerospace, and general industrial sectors.
Under our proprietary brand "Century Longhai" and via international strategic alliances with British "A Ba" series, our catalog spans heavy-duty diesel engine oil, high-spec gasoline motor oil, industrial gear oil, anti-wear hydraulic oil, special gear oil for natural gas power, urea solutions, and premium motorcycle oils. The long-term reliability of our products is underpinned by comprehensive quality insurance underwritten by PICC (People’s Insurance Company of China).
Operating from a state-of-the-art 131-acre smart production site, we run fully automated blending lines capable of outputting 200,000 tons annually. Our laboratories are equipped with analytical instruments (ICP emission spectrometers, gas chromatographs, and automated viscometers) to verify compliance at every production milestone.
Leveraging specialized chemical engineering resources, packaging machinery, and compliance mechanisms to construct custom brands.
Synthesizing fully synthetic base oils (PAO, Esters) with customized additive packages matching API, ACEA, and specific OEM specifications.
Flexible batch sizes, supporting both specialized small trial runs and multi-thousand ton commercial orders without production delays.
Every custom batch is documented with a Certificate of Analysis (COA) containing elemental spectroscopy and physical properties verification.
Complete packaging development including custom container modeling, multilingual label design, and compliance-driven documentation support.
Our automated filling plant utilizes high-precision mass flow meters and volumetric piston filling lines. Unlike standard timing-based filling systems, our metering technology maintains precision tolerances of 1‰ to 2‰, preventing product waste and ensuring volume compliance for international shipping.
Simultaneously, our automated systems improve filling output by 20% to 35% relative to conventional configurations. This technological margin enables our logistics department to guarantee fast lead times, regardless of the order volume or package profile (1-liter bottles, 4-liter canisters, 18-liter pails, or 200-liter drums).
Delivering high-integrity boundary lubrication, structural protection, and fluid life across major industrial environments.
Industrial hydraulic systems in injection molding, construction machinery, and steel mill controls operate under high fluid velocities and close tolerances. Our Longhai Anti-Wear Hydraulic Oil features shear-stable viscometrics and robust zinc-based (and zinc-free) anti-wear chemistries, ensuring fluid stability and preventing valve sticking under cyclic high-pressure conditions.
Mining mills, port cranes, and cement kiln gearboxes suffer from constant stop-start vibration and extreme pressure profiles. The L-CKC and L-CKD industrial gear oils are formulated with sulfur-phosphorus EP packages. This chemistry generates a sacrificial boundary layer at metal-to-metal friction spots, preventing scuffing, pitting, and catastrophic gear teeth failures.
Rotary screw and reciprocating air compressors experience extreme thermal stresses that accelerate oxidation and oil breakdown. Longhai compressor lubricants leverage high-purity synthetic hydrocarbons that resist carbon deposits and varnish formation, ensuring safety in heat-exchanger lines, reducing fire hazards, and maintaining stable compressor air flow.
Our base in Shandong places Longhai at the center of one of the world's most concentrated chemical and industrial manufacturing clusters. This geographic positioning ensures steady, reliable access to high-purity mineral and synthetic base fluids, preventing supply disruptions.
By utilizing localized raw material logistics, advanced additive integration, and high-efficiency shipping through Qingdao Port, we insulate our global clients from supply chain disruptions and volatile shipping rates.
Our direct integration with domestic refining groups guarantees base oil reserves even during peak global consumption periods. Additionally, Shandong’s specialized workforce ensures consistent operational performance, from batch blending to complex laboratory analysis.
Pioneering high-spec synthetic formulations, sustainable base chemistries, and nanotechnology for next-generation machinery.
Our quality policy is based on complete consistency. We have passed the strict benchmarks of ISO 9001:2015 (Quality Management System), ISO 14001:2015 (Environmental Management System), and ISO 45001:2018 (Occupational Health and Safety).
Furthermore, our specialized automatic transmission and motor oils carry authoritative certifications, including Mercedes-Benz (MB-Approval), ensuring that our formulations satisfy the tight tolerances defined by global automotive manufacturers.
Each batch is subjected to ASTM standard tests, checking kinvisc, flash point, pour point, CCS viscosity, and foaming properties, ensuring consistent quality for all end users.
