Explore our highly engineered range of industrial-grade base oils, synthetic formulations, and specialized high-shear gear lubricants.
In modern industrial manufacturing and high-stress automotive applications, the mechanical demands placed on gearbox components have intensified. High-load operations, extreme temperature fluctuations, and the critical need for micro-pitting resistance have driven the demand for highly optimized gear and driveline oils equivalent to class-leading standards like Comma Gear Oil.
As a premier wholesale gear oil manufacturer and supplier, Shandong Longhai Lubrication Technology provides high-shear stability lubricants formulated with premium synthetic base stocks and cutting-edge extreme pressure (EP) additive packages. Our formulations guarantee optimized friction coefficient reduction, robust film thickness under high shear rate conditions, and excellent thermal oxidation stability.
Established in 2009 and headquartered in Zibo, Shandong, Shandong Longhai Lubrication Technology Development Co., Ltd. is a national high-tech enterprise integrating R&D, production, sales, and comprehensive supply chain solutions. For over 15 years, we have built a complete, highly integrated industrial lubrication ecosystem.
Under our proprietary brand "Century Longhai" and our strategic international brand collaboration British "A Ba" series, we produce an extensive portfolio of heavy-duty diesel engine oils, high-performance gasoline engine oils, gear oils, hydraulic transmission fluids, anti-wear hydraulic fluids, specialized construction machinery lubricants, synthetic formulations, and eco-friendly diesel exhaust fluids (AdBlue). To assure maximum safety and business continuity for our global distributors, our product lines are fully backed and insured by the People's Insurance Company of China (PICC).
We combine advanced blending methodologies with global testing techniques to guarantee our gear oils operate flawlessly under severe thermal and mechanical stresses, successfully reducing mechanical failure, mitigating wear, and dramatically lowering maintenance overhead for the end user.
Leveraging China's leading chemical refining hubs and highly integrated logistics infrastructure to deliver cost-optimal lubrication solutions.
Spanning an expansive footprint of 131 acres, our manufacturing facility supports an annual production capacity of over 200,000 metric tons of lubricants. This scale ensures uninterrupted supply even during volatile global market conditions.
Equipped with computerized high-shear blending systems and precise automatic metering lines. Our volumetric and mass-flow filling precision remains strictly constrained within 1‰ to 2‰ deviation, maintaining consistent fluid quality across batched orders.
By automating the transition between compounding, processing, packaging, and sorting, we successfully increased global fulfillment and shipping dispatch velocity by 20% to 35% relative to generic regional toll blenders.
Exporting chemical compounds globally demands strict alignment with regional environmental codes and quality frameworks. Longhai Technology maintains comprehensive compliance pathways to ensure seamless custom clearances and local acceptance.
We are certified under ISO 9001:2015 (Quality Management), ISO 14001:2015 (Environmental Management), and ISO 45001:2018 / 18001 (Occupational Health & Safety). Furthermore, our specialized formulations have obtained official approvals, such as the prestigious Mercedes-Benz (MB) certification for automatic transmission fluids, proving our chemical standard is equal to the most stringent OEM demands.
For European, North American, and APAC distributors, we supply complete regulatory packs, including technical datasheets (TDS), safety data sheets conforming to GHS standards (SDS), and custom packaging options compliant with international hazardous goods handling directives.
Whether you require white-label alternatives to commercial lines like Comma Gear Oil or custom formulations tailored for regional climates, our technical labs deliver precise results.

From modern automotive hypoid axles to high-torque industrial worm drives, our lubricant products solve complex tribology challenges.
Modern passenger cars and light commercial vehicles require extreme shear stability under variable high-speed, high-torque configurations. Our specialized formulations maintain fluid boundary layer protection, preventing adhesive wear on hypoid differential teeth.
Heavy mining machines, cement mills, and steel works gearboxes require excellent thermal load carrying capacity. Our industrial L-CKD series is formulated to limit micro-pitting, running cooler and significantly extending oil drain intervals.
Wind energy conversion gear systems operate in remote locations with harsh thermal swings and high humidity. Our synthetic PAO-based fluids limit sludge formation, resist foaming, and provide exceptional rust prevention in offshore marine environments.
Combined transmissions, wet-brake, and final drive assemblies demand multifunctional oils. Our fluids optimize friction characteristics, eliminating brake chatter while assuring long-lasting gear protection.
The global lubrication landscape is undergoing a structural shift towards environmental sustainability and energy efficiency. OEMs are demanding lower viscosity fluids (such as 70W-75 or ISO VG 68/100) to minimize churning losses within mechanical assemblies, without sacrificing EHL film thickness. At Shandong Longhai, our lab engineers focus on developing high-polarity synthetic formulations that preserve molecule integrity at higher temperatures, ensuring compliance with global emission reduction standards.

Our premium gear oil formulations are designed using high-grade API Group III hydrocracked base oils or synthetic Polyalphaolefin (PAO) compounds, matching or exceeding typical performance properties found in lines like Comma Gear Oil. By sourcing proprietary additive systems that maximize micro-pitting resistance (tested under FZG load stages), we achieve comparable oxidation resistance, exceptional shear stability, and identical viscosity protection under extreme high-load and racing configurations.
Shandong Longhai holds active ISO 9001:2015, 14001:2015, and ISO 45001 environmental and health standards. For regional imports, we supply compliant GHS SDS (Safety Data Sheets) with updated REACH/OSHA classifications. Our industrial gear oils strictly comply with DIN 51517 parts 1, 2, and 3, ANSI/AGMA 9005-E02, and US Steel 224 requirements, eliminating regulatory friction during customs operations.
Yes. Our in-house research laboratory specializes in adjusting pour point depressants and selecting low-temperature synthetic base-stocks. We formulate custom gear lubricants that maintain fluid mobility down to temperatures of -45°C to -50°C, while preserving a robust fluid film at elevated operating conditions (high shear rate conditions above 150°C).
For fully custom blending runs featuring specialized additive configurations or custom branding bottles, the typical minimum run begins at 5 to 10 metric tons, depending on packaging size (e.g., 1-Liter bottles vs. 200-Liter industrial drums). For standard formulations packaged under our labels, we can support smaller pilot batches to accommodate distributor trials.
Our manufacturing facility utilizes a computerized recipe-blending system integrated with direct mass-flow sensors. Each finished batch is subjected to ASTM-certified laboratory protocols checking viscometrics, density, flashpoint, moisture levels, and elemental additive distribution before passing into our filling lines. Retained samples of every shipped batch are archived for 2 years to maintain absolute batch traceability.
