Engineered for maximum reliability, extreme pressure threshold, and advanced thermal stability under high load operations.
An in-depth look at macro-industrial dynamics, shear stability metrics, and high-performance alternative solutions for demanding drive systems.
Heavy industries worldwide, including marine cargo fleets, deep-surface mining installations, utility-scale wind power operators, and transnational logistics companies, require highly specialized gear oil formulations. In North American and European markets, procurement directors actively seek gear oils that match or exceed the strict specifications set by leading lubricant innovators like Lucas Oil. Key criteria include excellent demulsibility (the ability to separate from water), high viscosity index (VI) stability, and advanced extreme pressure (EP) additive performance.
As a reliable global supplier, Shandong Longhai Lubrication Technology Development Co., Ltd. addresses these specific demands. By formulating gear oils with premium base stocks and high-performance additive packages, we provide products that offer robust wear protection, thermal oxidation stability, and foam suppression. Our strategic supply options ensure global buyers can maintain efficient logistics while meeting the required technical specifications.
In high-performance applications, lubricants are subjected to continuous mechanical shear. Under boundary lubrication conditions—where the fluid film is compressed to molecular thickness—standard formulations can fail, leading to direct metal-to-metal contact, scuffing, and micropitting.
To address this, our formulations incorporate sulfur-phosphorus EP additives that react chemically with metal surfaces under extreme heat and pressure. This process forms a thin, protective sacrificial layer that minimizes friction and protects gear teeth from wear under shock-load conditions, keeping your equipment operating efficiently.
A leading high-tech enterprise dedicated to advanced lubrication formulation development and supply.
Established in 2009 and headquartered in Zibo, Shandong, Shandong Longhai Lubrication Technology Development Co., Ltd. has spent over 15 years developing industrial and automotive lubricants. With an emphasis on R&D and end-to-end quality control, we provide customized lubrication solutions for modern machinery globally.
We manufacture under our proprietary brand "Century Longhai" alongside our international strategic brand, the British "A Ba" series. Our comprehensive product portfolio includes diesel engine oils, passenger vehicle oils, heavy-duty gear oils, anti-wear hydraulic fluids, specialized marine lubricants, and high-performance agricultural fluids. Reflecting our commitment to quality, our products are backed by PICC China People's Insurance Company.
Our manufacturing facilities feature advanced blending technology and testing procedures to ensure consistent performance under extreme conditions, helping customers reduce maintenance costs.
Developing advanced formulation solutions to meet next-generation machinery specifications and environmental standards.
Our ongoing research centers on developing high-performance gear oils designed to reduce hydrodynamic drag while preserving film strength under extreme pressure conditions.
By using selected base stocks and oxidation inhibitors, we aim to extend drain intervals, helping industrial fleets reduce overall lubricant consumption and operational costs.
Our R&D efforts are focused on developing biodegradable formulations that maintain high mechanical shear resistance and protect components while minimizing environmental impact.
Our heavy-duty gear oils are formulated for major industrial sectors. In wind power generation, gearboxes require lubricants that prevent micropitting under variable wind speeds. In marine propulsion and thrusters, our oils are designed to maintain film strength and protect against corrosion even in the presence of salt water. For mining equipment, such as excavators and crushers, our extreme pressure packages are designed to withstand shock loads and heavy vibrations.
Longhai Technology operates a 131-acre production facility with an annual manufacturing capacity of 200,000 tons of premium lubricants. Our production lines feature automated systems that monitor temperature, blending speed, and ingredient ratios to ensure batch consistency.
Our automatic packaging lines utilize metering systems that maintain a filling precision of 1‰ to 2‰. This setup supports high packing efficiency and helps us manage delivery timelines for large-volume bulk orders.
Offering customized formulation development, private label packaging, and technical support to match your specific branding and application needs.
Our laboratory works to develop synthetic and mineral formulations designed to meet specific viscosity profiles, thermal conditions, or industrial specifications.
We supply private label packaging options in various sizes, ranging from retail bottles to bulk industrial drums (200L) and IBC totes.
Every product batch is analyzed to confirm performance, and we provide laboratory reports to support quality assurance.
