Engineered for maximum thermal stability, extreme wear protection, and extended drain intervals.
In modern industrial applications, rotary compressors and hydraulic transmission lines operate under extreme thermal stresses, high pressures, and corrosive environments. Standard mineral oils often degrade prematurely, leading to severe carbon buildup (varnish), thermal oxidation, mechanical friction losses, and catastrophic equipment downtime. As a premier global exporter of advanced lubrication solutions, Shandong Longhai Lubrication Technology Development Co., Ltd. (established in 2009 in Zibo, Shandong) delivers highly engineered synthetic and premium-refined lubricant formulations that extend equipment service life, maintain system pressure efficiency, and dramatically lower Total Cost of Ownership (TCO).
Under our proprietary brand "Century Longhai" alongside our international strategic cooperation brand—the British "A Ba" series, we have constructed an end-to-end industrial chain system. This system spans from intensive base fluid synthesis and additive formulation R&D to automated production, precise quality assurance, and global compliance distribution. All our product formulations are backed by comprehensive liability insurance via the PICC (China People's Insurance Company), ensuring absolute reliability and operational confidence for our distributors and global enterprises alike.
Adapting to green energy demands, carbon-neutral compliance, and high-efficiency operations.
Transitioning from Hydrocracked Group II mineral oils to fully synthetic polyalphaolefin (PAO) and high-tier ester-based oils. This technical route offers exceptional shear stability, an extremely high viscosity index (VI), and superior hydrolytic stability under intense pressure conditions.
Developing specialized low-deposit ashless dispersants and high-temperature antioxidants. These proprietary chemical configurations effectively capture radical oxidation precursors, eliminating the formation of sticky varnish coatings on internal compressor rotors, cooling lines, and separator elements.
Pioneering biodegradable ester lubricants for environmentally sensitive sectors such as marine, offshore wind power generation, and agricultural equipment. This ensures compliance with stringent international environmental frameworks without sacrificing wear resistance.
Engineered formulations tailored to solve operational challenges across diverse industrial verticals.
Heavy duty gear setups, high-temperature rolling mills, and extreme-load hydraulic lines require superior thermal stability. Longhai's heavy-duty industrial gear oils (such as L-CKD) maintain critical film thickness under high shock-load environments to prevent micropitting and component failure.
From highly specialized passenger vehicle engine oils (API SP/SN) to heavy-duty commercial fleet diesel engine lubricants (API CK-4/CJ-4), our products ensure low oil consumption, optimal fuel economy, and outstanding soot dispersancy for extended highway operations.
High-efficiency gas and steam turbine systems require lubricants with immaculate water separability, high resistance to foaming, and exceptional oxidative life. Our premium turbine oils prevent system sludge buildup, keeping critical bearing housings clean and operational.
HVAC and industrial refrigeration units require specialized lubricants that maintain outstanding low-temperature fluidity and compatibility with modern eco-friendly refrigerants. Our refrigeration oils prevent wax precipitation and blockages in expansion valves.
Operating in environments saturated with abrasive dust and extreme moisture requires highly robust hydraulic transmission fluids and anti-wear hydraulic oils. Our formulations keep control valves free from contamination and minimize component fatigue.
Operating out of a state-of-the-art manufacturing campus spanning 131 acres, Longhai Technology maintains a massive annual production capacity exceeding 200,000 tons of premium lubricants. By employing Industry 4.0 automated blending processes and intelligent DCS (Distributed Control Systems), we ensure absolute batch-to-batch consistency and high structural purity across all fluid categories.

Ensuring cross-border compliance, environmental responsibility, and prestigious manufacturer certifications.
Longhai Technology operates with an unyielding commitment to international operational standards. We have successfully passed the three major management system certifications: ISO 9001:2015 Quality Management, ISO 14001 Environmental Management, and ISO 45001/18001 Occupational Health and Safety Management Systems.
Furthermore, our automatic transmission lubricants have attained official Mercedes-Benz (MB) certifications, demonstrating our ability to meet the stringent technical criteria defined by the world's most demanding OEMs. For global importers, distributors, and bulk purchasers, we provide full localization documentation, including detailed Safety Data Sheets (SDS) matching GHS/OSHA standards, Certificates of Analysis (COA) for every shipment, custom labeling options, and customs compliance support to guarantee frictionless import processes.






Tailor-made lubricants formulated to your brand’s standards, application demands, and market conditions.
We consult with your engineering and commercial departments to identify precise target parameters: operating temperatures, viscosity grades (ISO VG), target base stocks, oil drain expectations, and environmental conditions.
Our lab designs customized formulation prototypes using premium synthetic bases (PAO, diester, polyol ester) and custom additive chemistry package systems to meet and exceed API, ACEA, and specific OEM requirements.
Before moving to industrial-scale production, prototypes undergo exhaustive simulation stress testing, including Four-Ball Wear Tests, RPVOT oxidation resistance, copper strip corrosion evaluation, and foaming characteristics analyses.
Upon client sign-off, we schedule high-volume automated blending. We assist in design and packaging options ranging from 1L bottles to 200L steel drums and 1000L IBC totes, followed by complete logistics handling.
A proven, transparent workflow ensuring efficient deployment from technical design to global shipping.
Clients specify machinery types, viscosity targets, and performance standards.
Our laboratory tailors additive packages for specialized climate and load demands.
Validation of chemical registry, SDS safety sheets, and customs paperwork.
Safe dispatch via optimized marine container transport with tracking.
Providing clear, engineering-backed answers to critical questions commonly encountered by purchasing directors and plant engineers.
Providing advanced wear protection, shear stability, and maximum engine cleanliness.
At Longhai Technology, we firmly believe that products represent character and quality represents life. We continue to drive technical innovation, upgrade manufacturing efficiency, optimize logistics routes, and provide attentive technical services.
