Engineered to meet stringent global specifications (API, ACEA, and OEM certification) ensuring smooth operations under extreme industrial loads.
Industrial machinery today operates under conditions of increasingly high pressure, heavy friction, and severe thermal load. Traditional mineral-based lubricants frequently encounter molecular breakdown, oxidation, and accelerated viscosity shear, which leads directly to equipment down-time and excessive mechanical wear. As a premium manufacturer in China, Shandong Longhai Lubrication Technology Development Co., Ltd. has formulated synthetic gear solutions designed to address these distinct operational vulnerabilities.
By Utilizing synthetic polyalphaolefin (PAO) and synthetic ester base stocks alongside advanced sulfur-phosphorus extreme-pressure (EP) additives, our lubricants provide a high viscosity index (VI) and superior load-carrying capacities. The high-shear stability ensures a durable hydrodynamic lubrication film is maintained across gear teeth meshing areas, mitigating micro-pitting, sliding wear, and shock-load failure modes.
Our solutions provide excellent thermal oxidative resistance, preventing the formation of carbon sludge at elevated temperatures (up to 150°C), while remaining highly fluid during low-temperature start-ups (-40°C). This thermal flexibility translates directly to decreased maintenance cycles and extended operational life spans for high-torque gear configurations.
Formulated with anti-micropitting chemistry that prolongs gear surface longevity under intense contact pressures and sliding velocities.
Delivers up to 3-5 times the service life of traditional mineral oils, significantly reducing oil replacement and disposal costs.
Established in 2009 in Zibo, Shandong, Shandong Longhai Lubrication Technology Development Co., Ltd. is a recognized national high-tech enterprise integrating R&D, advanced manufacturing, and global sales. Spanning an expansive manufacturing base of 131 acres, we produce up to 200,000 tons of high-performance lubricants annually.
Our premier brand, "Century Longhai", along with our strategic international partnership line "A Ba", covers motor, industrial, transmission, and specialized gear oils. Backed by extensive quality assurance coverage through the People’s Insurance Company of China (PICC), our products provide dependable operations across global markets.
With an intensive investment infrastructure directing over 5% of annual revenue to laboratory R&D, we actively collaborate with domestic universities and international chemical laboratories to innovate and refine formulation efficiencies.




Providing custom formulations, rapid order execution, and cost efficiencies for global purchasers.
Our automated production facilities feature intelligent metering filling technology, achieving a precision rate of 1‰-2‰. This processing accuracy increases bottling efficiency by 20%-35%, ensuring high output speeds with zero batch inconsistency.
Located in Zibo, Shandong—a major petrochemical hub—we leverage localized material sourcing, reducing base oil logistics costs. This geographical integration allows us to offer competitive bulk pricing without compromising component purity.
Our internal analytical laboratory operates advanced ICP spectrometers, FZG gear test rigs, and cold-cranking simulators, validating batch safety and operational load limits prior to distribution.
Engineered to protect critical assets across high-stress industrial applications.
