Explore our high-performance motor oils, anti-wear hydraulic fluids, industrial gear oils, and specialized synthetic formulations engineered to meet demanding API/ACEA and DIN performance criteria.
Established in 2009, Shandong Longhai Lubrication Technology Development Co., Ltd. (headquartered in Zibo, Shandong) has pioneered lubrication technologies for over 15 years. Operating a state-of-the-art 131-acre smart factory, we combine academic partnerships and chemical research to develop advanced oils. Under our brand "Century Longhai" and the strategically cooperative UK brand "A Ba", our offerings span diesel and gasoline engine oils, gear oils, hydraulic transmission fluids, automatic transmission fluids, antifreeze, motorcycle oils, automotive urea solutions, and custom industrial oils.
To assure absolute reliability, our product range is backed by comprehensive quality liability insurance from PICC (People's Insurance Company of China). This reflects our dedication to safeguarding heavy industrial machinery and transportation fleets under extreme, continuous operating conditions.
The industrial landscape is undergoing a transition from standard mineral-based lubricants to synthetic esters and polyalphaolefins (PAO). Rotary screw and reciprocating piston air compressors are now operating under high pressures and compact thermal profiles, causing elevated discharge temperatures. These operating conditions trigger rapid thermal degradation, oxidation, and deposit formation (varnish) in low-grade oils, resulting in mechanical failures and reduced efficiency.
Advanced blending facilities address these challenges by formulating lubricants that prioritize high thermal-oxidative stability, low volatility, and rapid demulsibility. The latest formulations incorporate shear-stable polymer technologies and premium antioxidant packages. These additives neutralize acidic combustion and oxidation byproducts before they deposit on critical rotors and separation membranes. This dynamic chemical engineering extends maintenance intervals up to 8,000 hours in flooded rotary screw configurations.
Resists oil thinning and degradation under continuous operating temperatures exceeding 100°C.
Advanced additive chemistry suspends precursors to prevent deposit buildup on screw rotors.
Quickly separates water from the oil phase, maintaining lubrication and preventing internal rust.
Global procurement teams demand verified compliance with rigorous performance indicators. Industrial lubricants must exceed baseline standards like DIN 51506 (specifically VDL standards for high-temperature piston compressors) and ISO DP 6521. Key procurement criteria include:
To reduce operating costs, purchasing managers seek suppliers that offer consistent batch-to-batch quality, international logistics capacity, and technical support. Purchasing directly from verified Chinese manufacturers provides access to custom formulations engineered for specific ambient temperatures, load demands, and operating cycles.
Longhai Technology operates an advanced manufacturing system designed to meet high industrial demands. Utilizing smart controls, our 131-acre manufacturing facility achieves an annual throughput of 200,000 tons. Our production floor features automated blending and filling systems that regulate fill volume tolerances within 1‰ to 2‰. By upgrading process automation, we have improved filling cycle times by 20% to 35%, ensuring rapid lead times for bulk orders.
Our quality control protocol monitors the production line from raw base oil selection to final packaging. Each product batch undergoes chemical analysis within our labs to verify kinematic viscosity, flash point, pour point, water content, and foam stability. This production framework allows us to offer reliable, cost-effective alternatives to premium international lubricant brands.
Scalable blending plants ensure consistent, on-time delivery of large global contract orders.
High-precision dosing technology ensures consistent product properties across every batch.
All products are underwritten by PICC, offering operational security and liability protection.
Our lubricants are engineered to perform across diverse industrial environments. High-performance air compressors, heavy hydraulic machinery, and complex gear drives require specific lubricant profiles depending on their application:
Our high-efficiency compressor oils lubrication ensures stable pneumatic pressures for robotic lines, reducing varnish-induced downtime and filter replacements.
L-CKD heavy-duty gear oils provide extreme-pressure protection for planetary gears and mining equipment operating under high torque and impact loads.
Longhai Anti-Wear Hydraulic Oils protect multi-stage vane and piston pumps in construction machinery, maintaining fluid flow across varying operating temperatures.
To ensure international product consistency, our production site is certified under the ISO 9001:2015 Quality Management System, ISO 14001:2015 Environmental Management System, and ISO 45001:2018 Occupational Health and Safety System. Our lubricants are formulated to meet international manufacturer standards, including Mercedes-Benz (Daimler) fluid certifications for automatic transmission applications. These certifications demonstrate our capacity to formulate high-performance products that protect machinery in harsh industrial environments.
