Advanced lubrication engineering formulated to protect industrial equipment under extreme operations.
15+ Years of Dedicated Expertise in R&D, Formulating, and Smart Blending of Industrial Oils
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, large-scale production, and global sales networks. For more than 15 years, we have built a complete upstream-to-downstream industrial system dedicated to bringing cutting-edge, high-stability lubrication solutions to global heavy industrial sectors and transit systems.
Longhai Technology manufactures products under our proprietary brand "Century Longhai" alongside our strategically licensed international brand, the British "A Ba" series. Our comprehensive catalog ranges from diesel and gasoline engine oils, specialized heavy gear lubricants, high-grade transmission fluids, anti-wear hydraulic oils, natural gas engine lubricants, to fully synthetic refrigeration oils, eco-friendly urea fluids, and high-efficiency heat exchange media. In alignment with our commitment to reliability, our entire product range is fully backed by quality assurance policies underwritten by the PICC (People’s Insurance Company of China).




The science of maximizing uptime, extending drain intervals, and minimizing mechanical wear.
Utilizing high-purity Group IV base oils to guarantee exceptional shear stability and thermal performance under extreme compression ratios. Our PAO formulations offer superior heat dissipation, reducing the varnish and carbon build-up common in traditional rotary screw compressors.
Engineered to operate reliably across a vast temperature delta (-40°C to over 200°C). By modifying intermolecular bonding, we minimize cold-start wear while maintaining a protective lubricating film thickness during peak temperature phases.
Formulated with advanced antioxidant packages that inhibit molecular polymerization caused by chemical reactions with oxygen and atmospheric moisture. This effectively doubles typical drain intervals to over 8,000 operational hours.
Industrial screw and reciprocating air compressors represent the lifeblood of modern manufacturing environments. Standard mineral oils fail to survive the relentless thermal cycles, high mechanical pressures, and exposure to condensed atmospheric water. This degradation results in oxidation products: micro-varnish deposits that build up on precision rotors, causing increased friction, elevated bearing temperatures, and eventually costly mechanical failure.
Longhai’s synthetic formulas utilize a tailored combination of Group IV PAO and Group V Ester/PAG chemistry. These synthetic ester additions possess polar characteristics that clean existing lacquer deposits from inside the system while maintaining superior seal compatibility, preventing leak paths, and optimizing the thermal transfer properties of the fluid.
Combining world-class production volumes with ultra-precise processing controls.
Longhai Technology operates a state-of-the-art production base covering 131 acres in Shandong's heavy industrial hub. Our plant features an annual capacity of 200,000 tons. By integrating automated batching, DCS computerized control systems, and sterile raw material pipelines, we eliminate human contamination variables during critical formulation steps.
Our filling operations are equipped with fully automatic metering filling lines. Operating on precise weight-control and volumetric principles, these lines maintain a strict filling accuracy tolerance of 1‰ to 2‰. Additionally, our automated lines increase packaging speeds by 20% to 35% compared to semi-automated methods. This efficiency guarantees that bulk export shipments are completed rapidly, ensuring global supply chain consistency even during peak seasonal demands.
With Zibo’s strategic proximity to major logistics hubs and international shipping ports (such as Qingdao Port), we maintain reliable ocean and overland freight routes. We secure our base oils and additive components through direct long-term partnerships with leading global chemical producers. This insulation from local supply volatility ensures that we can scale production rapidly for major OEM clients without long delays.
Pioneering the next generation of eco-conscious, high-performance industrial lubricants.
Developing next-gen lubricants using bio-synthetic bases that degrade naturally. Perfect for food-grade processing and offshore applications where accidental leaks must have minimal environmental impact.
Engineering specialized synthetic lubricants designed for hydrogen compression. Our chemically inert base oils resist reaction with gas streams, keeping hydrogen fuel cells clean and free of contamination.
Integrating real-time sensor technologies to track oil conditions. By monitoring viscosity, water content, and oxidation levels, we help operators schedule maintenance based on actual wear, reducing waste.
Our long-term R&D plan aims to decrease corporate carbon footprints without sacrificing mechanical protection. Longhai invests over 5% of its annual revenues into joint research programs with leading technical universities and chemical academies. Our team works to optimize additive chemistries, lowering overall friction coefficients within compressors. This improvement helps reduce energy usage, supporting our global partners in hitting their net-zero operational targets.
Targeted formulations engineered for diverse operating environments and compressor types.
Screw compressors demand lubricants that act as dynamic sealants, heat transfers, and anti-wear agents. Longhai's synthetic screw compressor oils are built with low-volatility synthetic base stocks. This prevents vaporization under heavy workloads, significantly reducing oil carryover into downstream air systems.
Reciprocating piston designs create high shear stresses along cylinder walls, alongside hot discharge valves. Our specialized high-temperature formulations resist carbon deposit build-up, protecting valves from sticking and minimizing the danger of fire or explosion. For centrifugal systems, our lubricants provide low foaming and rapid air-release qualities to protect high-speed bearings.
Refrigeration systems require oils that mix well and remain fluid at low temperatures. Our synthetic refrigeration oils are chemically designed to work with modern HFC, HFO, and natural refrigerants like CO2 (R-744) and Ammonia (R-717). They prevent wax separation, ensuring high heat exchanger efficiency even in extreme sub-zero systems.






Global standards, local support networks, and certified production excellence.
Longhai Technology maintains strict compliance with major international manufacturing standards. Our facility has earned certifications including ISO 9001:2015 for quality management, ISO 14001:2015 for environmental management, and ISO 45001:2018 (formerly OHSAS 18001) for occupational health and safety. Furthermore, our formulations have received official approvals, such as the Mercedes-Benz automatic transmission fluid certification, confirming our high quality standards.









To support our growing network of international distributors, we provide localized technical documentation, MSDS/SDS sheets translated into target languages, and comprehensive customs clearance assistance. By partnering with global testing organizations like SGS and Intertek, we ensure our shipments arrive with reliable, transparent batch analytics, expediting customs entry globally.
