Shandong Longhai Lubrication Technology Development Co., Ltd. was established in 2009 and is headquartered in Zibo, Shandong. As a leading high-tech enterprise, we integrate research and development, smart manufacturing, and global trade under one roof. Deeply rooted in the lubrication industry for more than 15 years, our enterprise has established a resilient industrial supply chain.
We proudly market our proprietary brand "Century Longhai" alongside our international strategic partner brand, the British "A Ba" series. Our extensive fluid engineering portfolio includes diesel engine oil, gasoline engine oil, gear oil, hydraulic transmission oil, anti-wear hydraulic oil, specialized lubricants for engineering machinery, natural gas engines, motorcycles, and automatic transmission oils, alongside auxiliary fluids like automotive urea and antifreeze. In our pursuit of absolute reliability, our product range is fully backed by PICC China People's Insurance Company.
How we advance gear treatment oils from base formulation chemistry to next-generation extreme pressure protection.
Our formulation engineers utilize customized colloidal sulfur-phosphorus molecules and organometallic compounds. This chemical synergy builds a molecular boundary layer under high thermal friction loads, mitigating micro-pitting (FVA 54) and fatigue wear in heavy gear systems.
Using premium shear-stable polymeric viscosity index modifiers, our gear treatment lubricants prevent fluid film breakdown in high-shear environments. Operating efficiency is maintained across operating temperatures from -40°C to 150°C.
Responding to ESG initiatives, our R&D roadmap targets synthetic ester-based biodegradable lubricants. These formulas match traditional polyalphaolefins (PAO) in performance while reducing environmental impact in offshore and agricultural applications.
Innovation drives our development. Longhai allocates more than 5% of its annual revenue to R&D, collaborating with leading academic research institutions. This allows us to optimize formulation chemistry and develop custom solutions for unique operating environments.
High-torque gearboxes in planetary mills, mining excavators, and conveyor systems demand exceptional load-bearing capacities. Our gear treatment oils resist oxidation and prevent micro-pitting under high shock loads, extending equipment lifetimes.
Remote wind installations require low-maintenance lubricants. Our formulation prevents foam buildup and protects bearings from micro-pitting under erratic load conditions, reducing costly maintenance intervals.
Port cranes and marine propulsion thrusters operate in corrosive, wet environments. Our gear fluids deliver water separation (demulsibility) and rust prevention, ensuring reliable operations under continuous exposure to sea spray.
Longhai Technology operates an advanced blending plant that utilizes metering filling systems to ensure high filling accuracy of 0.1% to 0.2% (1‰ - 2‰). This automated process minimizes waste and delivers consistent product volumes across every batch.
By integrating advanced automation into our packaging lines, we have increased filling speeds by 20% to 35%. This efficiency enables us to manage bulk wholesale orders and secure delivery schedules for our global partners.
"Our 131-acre manufacturing center yields up to 200,000 tons annually, providing a robust supply chain to insulate customers from raw material disruptions."
International industrial lubricant distribution requires strict compliance and quality controls. We maintain comprehensive certifications to meet global standards and cross-border regulatory demands.
Longhai has passed ISO 9001:2015 (Quality System), ISO 14001:2015 (Environmental Management), and ISO 45001:2018 (Occupational Health Management) certifications. This guarantees our operations align with international standards.
Our automatic transmission and industrial gear formulations carry global OEM approvals, including Mercedes-Benz certifications. This ensures cross-compatibility and maintains machinery warranties.
We support imports with full chemical documentation, including localized Safety Data Sheets (SDS), GHS compliance labeling, and custom clearance paperwork for seamless shipping.
We formulate synthetic, semi-synthetic, and mineral-based lubricants tailored to specific machinery demands, operational climates, or target market standards (including API, ACEA, and DIN specifications).
