Explore our globally exported line-up of industrial-grade lubricant products, including heavy-duty motor, gear, and high-efficiency air compressor mineral oils.
In modern manufacturing, industrial air compressors operate under intense mechanical stress, fluctuating thermal environments, and continuous oxidation cycles. Sourcing the Best Compressor Mineral Oil is a fundamental operational imperative. Refined from high-quality paraffinic base stocks (Group I and Group II), specialized compressor mineral lubricants form a durable tribological barrier on critical rotating elements.
Unlike standard hydraulic or motor oils, compressor mineral oil is specifically formulated to mitigate carbonaceous deposit formation on valves, rotor chambers, and separator elements. Under pressures reaching up to 15 bar and temperatures exceeding 100°C, typical base oils degrade rapidly, leaving behind sticky residues, varnishes, and lacquer coatings. Shandong Longhai's mineral compressor lubricants address this issue directly by incorporating thermal-oxidative inhibitors that resist thermal cracking.
In screw compressors, the lubricant does more than reduce friction—it acts as a coolant, a sealant, and a shock absorber. This multifunctional profile demands superior water-separation characteristics (demulsibility) and high hydrolytic stability, preventing condensed atmospheric moisture from degrading the oil and corroding interior components.
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.




Longhai Technology combines automated manufacturing scale with advanced product customizability, helping global distributors and OEM customers secure market-leading pricing without compromising on technical quality.
Longhai Technology has always insisted on innovation-driven development. Its annual R&D investment accounts for more than 5% of its annual revenue. It has established strategic cooperation with many universities and scientific research institutions to continuously optimize lubrication technology and promote industry progress.
The company has advanced blending and fully automatic production and filling equipment. The filling production line adopts the principle of metering filling, which is suitable for filling various lubricating oils and ensures the filling accuracy of 1‰-2‰. While ensuring the filling accuracy, it increases the filling speed by 20%-35%, effectively increases the work efficiency, and realizes the standardized production of the enterprise.
Our products undergo testing inside our precision laboratories. Underwritten by the People’s Insurance Company of China (PICC), every batch of lubricants we export is backed by comprehensive product liability protection, giving our global strategic partners absolute peace of mind.
From localized cold-chain logistics to heavy metal processing industries, our products cover diverse application requirements.
In refrigeration compressors, the refrigerant (such as ammonia or fluorocarbons) is in continuous contact with the lubricant. Our Professional-grade refrigeration oil prevents phase separation, wax precipitation, and high-temperature oil thinning, ensuring optimal heat exchange performance in commercial cold chain systems.
Heavy industries such as mining and wind power require gear lubricants that prevent micro-pitting. Shandong Longhai's L-CKC and L-CKD heavy-duty gear oils prevent wear under severe sliding pressure, reducing machinery downtime in rugged operating conditions.
Hydraulic machinery operating in manufacturing plants relies on high shear-stability anti-wear fluids. Our Anti-wear hydraulic oil prevents pump wear and valve sticking under continuous pressure, maintaining system efficiency.
We provide heavy-duty engine lubricants such as CJ-4, CF-4, and CH-4 synthetic diesel engine oils. These formulations are designed to handle soot loading, piston deposits, and ring wear in high-mileage logistics fleets and off-highway construction machinery.
We provide complete private label services, formulation engineering, and custom packaging designs to align with your brand positioning.
Tailored synthetic and mineral lubricant recipes engineered to exceed API, ISO, and ACEA requirements.
From pilot trials to high-volume commercial runs across our automated filling systems.
