Explore our high-performance product range engineered to safeguard machinery, optimize gear systems, and withstand extreme pressures.
Modern transmission systems in industrial, automotive, and off-highway sectors run under higher torque, higher power densities, and tighter tolerance margins than ever before. Gear oil, the critical barrier between metal interfaces, must perform beyond basic lubrication. It acts as a thermodynamic transfer medium, a corrosion preventative, and a primary defense against micro-pitting and surface fatigue.
Shandong Longhai Lubrication Technology Development Co., Ltd. (established in 2009) has spent over 15 years cultivating the precise tribological chemistry required for complex industrial and heavy-duty gearboxes. With strategic licensing and collaborative formulation under the international British "A Ba" (Abro/Abros) brand pedigree, we offer global procurement teams the technical superiority of premium European design alongside the agility and efficiency of Chinese state-of-the-art production.
Why Tier-1 industrial buyers, global distributors, and heavy machinery operators rely on Shandong Longhai Lubrication Technology.
Equipped with smart production lines and advanced laboratory testing, we tailor viscosity indices, pour points, and extreme pressure (EP) chemistry to meet specific climate, thermal load, and operating parameters.
Our operations are fully certified under ISO 9001-2015 (Quality Management), ISO 14001 (Environmental Standards), and ISO 18001 (Occupational Health), establishing an unyielding baseline for batch stability.
Leveraging specialized British Abro chemical expertise, we deliver high-integrity packaging design, label compliance, and technical data sheets (TDS) that confidently secure market positioning.

Modern gear design demands high-performance lubricants. Current market dynamics shaping gear oil formulation include:
1. Increased Thermal Densities: Compact gearboxes running at higher speeds generate elevated operating temperatures. This demands high-viscosity-index base stocks that resist thermal shear, deposit formation, and varnish buildup.
2. EV and Hybrid Drivetrain Integration: Automotive gear oils are evolving to handle high rotational speeds, specialized electrical insulation, and copper wire compatibility. Fluid formulation must balance excellent dielectric properties with mechanical wear prevention.
3. Advanced Micropitting Prevention: Surface fatigue on gear teeth, known as micropitting, can degrade transmission gear profiles. The British "A Ba" (Abros) gear oil series is formulated with specialized sulfur-phosphorus extreme pressure (EP) chemistry to prevent micropitting and protect gear geometry under extreme shock loads.
4. Eco-Friendly and Energy-Efficient Lubricants: Biodegradable synthetic gear oils (ester and PAO-based) are increasingly used in offshore marine, forestry, and sensitive agricultural settings. Our R&D center partners with universities to develop low-traction-coefficient synthetic formulations that reduce internal friction and improve overall transmission efficiency.
