In the modern heavy industry landscape, the efficiency of mechanical transmission depends highly on high-performance industrial gear oils. As global industries upgrade towards higher loads, more compact designs, and extreme environmental challenges, the demand for lubricants that meet or exceed benchmark standards such as Veedol Gear Oil specifications has surged. Lubrication systems must prevent micro-pitting, gear wear, and oxidation under high temperature and shear stress.
Shandong Longhai Lubrication Technology Development Co., Ltd. has established itself as a premier exporter of industrial and automotive lubricants, formulating equivalent lines that match the extreme-pressure (EP) characteristics of top Veedol gear lubricants. Leveraging over 15 years of chemical engineering and manufacturing research, we supply global industries with robust replacements for L-CKC and L-CKD heavy-duty gear fluids, engineered with advanced additive packages to sustain elastohydrodynamic lubrication (EHL) under boundary contact conditions.
How our advanced molecular formulation stands as a direct counterpart to top-tier international brands like Veedol.
By blending Group II and Group III hydrocracked base oils with premium polyalphaolefins (PAO), we achieve outstanding shear stability. Under high pressures, our lubricating film remains structurally sound without thermal breakdown, protecting gears from surface fatigue and pitting.
Our gear oils utilize a thermochemically balanced sulfur-phosphorus EP additive system. When heavy load friction generates local heat, these additives react with the metal surface to form a sacrificial protective tribofilm, preventing welding, scuffing, and wear.
In humid industrial environments, water ingress can destroy oil film structure. Our formula contains high-efficacy demulsifiers that separate water from the oil layer swiftly, while preventing aeration and foam generation inside gearboxes.
Shandong Longhai Lubrication Technology Development Co., Ltd. was established in 2009 and is headquartered in Zibo, Shandong. It is a high-tech enterprise integrating R&D, production, and sales. The company has been deeply involved in the lubricant industry for more than 15 years, has built a complete industrial chain system, and is committed to providing high-quality lubrication solutions for the global industrial and transportation fields.
As a reliable lubricant manufacturer in the industry, Longhai Technology owns its own brand "Century Longhai" and the international strategic cooperation brand British "A Ba" series of products. The products cover diesel engine oil, gasoline engine oil, gear oil, hydraulic transmission oil, anti-wear hydraulic oil, special engine oil for engineering machinery, special oil for natural gas, full synthetic oil, automotive urea solution, antifreeze, special engine oil for motorcycles, industrial oil, automatic transmission oil and many other lubricant varieties. The brand is insured by PICC China People's Insurance Company and quality insurance.
The company's production base covers an area of 131 acres, with an annual production capacity of 200,000 tons. It is equipped with intelligent production lines and precision laboratories to meet the customized needs of different customers.

Industrial gearboxes operate in diverse and hostile settings, prompting a shift from traditional mineral-based gear oils to synthetic equivalents that maintain stability across temperature fluctuations. In high-demand sectors like wind power generation, mining, metal rolling, and maritime shipping, lubricants must withstand intense mechanical stresses while lengthening drainage cycles to reduce operating costs.
Our high-performance worm and industrial gear oils, meeting L-CKC and L-CKD standards, serve as reliable alternatives to Veedol's gear range. These products are formulated to combat micro-pitting—a type of surface fatigue that damages tooth profiles and causes transmission failure. With advanced thermal stability, our products resist oxidation and deposit formation under high operational temperatures, ensuring clean gearcases and smooth operations.
