Advanced heavy-duty and synthetic fluid solutions engineered for global industrial and automotive standards.
Addressing the shifting dynamics of power transmission systems in heavy industry, wind energy, and transportation.
Modern industrial gear systems are subjected to higher power densities, compact housing designs, and extreme operational environments. As global markets transition towards high-output planetary gear systems and electric drive systems, standard lubricant formulations fall short. Demands for multi-functional extreme pressure additives, high thermal stability, and extended oil drain intervals have transformed gearbox lubrication from a simple maintenance commodity into a core engineered system component.
Global procurement networks require high reliability, stable supply capacities, and strict compliance profiles. Wholesale distributors, industrial maintenance companies, and original equipment manufacturers (OEMs) look for reliable partners that combine production volume with custom formula flexibility. Our logistical capabilities span continents, ensuring that high-grade synthetic gear oils (such as L-CKC and L-CKD) reach global shipping ports on schedule with full regulatory clearances.
Across processing plants, mining mills, and marine propulsion systems, failures due to micropitting, foaming, and sludge formation cause heavy financial losses. System engineers must prioritize high-quality lubricants containing advanced anti-friction chemistries. Shandong Longhai Lubrication has addressed this worldwide by engineering premium formulas featuring British "A Ba" technologies, delivering high-performance wear protection and maintaining optimal viscosity profiles under high loads.
Custom chemical engineering designed to extend machinery lifespan and lower total operational costs.
By blending Polyalphaolefin (PAO) and premium ester base oils with sulfur-phosphorus extreme pressure (EP) additives, our industrial gear lubricants exhibit outstanding viscosity indices and oxidative resistance. They remain operational in sub-zero start-up conditions and hold strong fluid films at continuous operating temperatures exceeding 120°C.
Micropitting is a type of fatigue wear that destroys gear tooth profiles, resulting in costly rebuilds. Our L-CKD heavy-duty gear oils are formulated to generate a stable, microscopic protective barrier on metal surfaces. This active boundary layer distributes pressure spikes across microscopic peaks, protecting gear sets from scuffing, pitting, and catastrophic failure.
In humid industrial environments, water ingress can emulsify oil, leading to cavitation and lubrication loss. Our proprietary demulsibility additives separate water quickly, allowing easy drainage from oil sumps. Furthermore, rapid air release properties prevent foam formation, maintaining steady fluid pressure in high-speed, agitated gearbox sumps.

Developing next-generation lubrication technologies focused on efficiency, sustainability, and extended service life.
To support corporate environmental goals, we are expanding our range of biodegradable synthetic ester gear oils. These fluids decompose quickly in sensitive soil or marine environments while matching the load capacity and oxidation resistance of mineral oils.
High-speed electric drivetrains require lubricants with excellent thermal management, material compatibility, and foam control. We are developing low-viscosity, high-film-strength fluids that optimize energy transfer efficiency in electric vehicle systems.
We are researching nano-particle additives that deposit a protective, low-friction layer on gear teeth. These particles fill surface micro-scratches under load, reducing friction coefficients and increasing overall energy efficiency in heavy machinery.
Answers to common technical questions about selecting, applying, and maintaining industrial gear lubricants.
L-CKC oils are formulated for medium-load industrial gear systems operating under mild pressures and temperatures. L-CKD oils are designed for heavy-duty systems running under extreme pressures, high temperatures, and severe shock loads. L-CKD features superior anti-wear, anti-micropitting, and oxidation resistance compared to L-CKC.
Synthetic gear oils (using PAO or esters) offer a higher viscosity index, better thermal stability, and lower traction coefficients than mineral oils. They operate across wider temperature ranges, reduce friction losses to save energy, and resist oxidation to extend oil drain intervals by up to three times.
Micropitting is a type of surface fatigue that creates microscopic cracks and pits on gear teeth, eventually leading to teeth fracture. Our gear lubricants prevent this by using advanced extreme-pressure and anti-wear additives. These compounds form a protective film on gear tooth surfaces, distributing localized pressure spikes.
