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.
In modern automotive architectures, the Continuously Variable Transmission (CVT) stands out as a core design choice for optimize engine efficiency, offering seamless gear transitions and highly stable power delivery. However, the operational stresses applied on CVT fluids are radically different from standard step-automatic transmission systems. Understanding these nuances is critical for automotive designers, fleet managers, and industrial procurement officers.
The global demand for high-efficiency passenger cars has driven automotive manufacturers to expand their deployment of push-belt and chain-type CVTs. From the bustling metropolitan corridors of East Asia to the highway infrastructures of North America, these transmissions are standard in modern commuters. The global market requires lubricants that offer long-term stability, excellent cooling profiles, and high torque capacity. The transition towards CVTs is not merely a design trend but a regulatory response to fuel consumption demands and environmental protocols.
Standard transmissions rely on wet clutches for power transfer, requiring paper-on-steel friction optimization. A CVT, conversely, transfers massive drive forces through a steel belt or chain pressed tightly between steel pulleys. Consequently, CVT fluids must exhibit exceptionally high steel-on-steel friction coefficients to prevent micro-slipping, which causes heat buildup, wear, and mechanical failure. Simultaneously, the fluid must provide optimal anti-wear properties at the contact points to extend system lifespan. Shandong Longhai’s advanced CVT formulation maintains this balance, ensuring efficient torque transfer under extreme stress.
Maintains dynamic viscosity under the high shear stress generated within CVT metal belt contact zones, preventing premature fluid breakdown.
Operates as an effective cooling medium, channeling heat away from critical pulley sheaves and gear meshes during prolonged engine cycles.
Contains proprietary friction modifiers that stabilize clutch engagements and torque converter lockups, eliminating vehicle shudder.
To withstand extreme operating temperatures, our premium CVT formulations utilize synthetic base stocks (Group III and PAO) combined with balanced additive packages. The viscosity index (VI) is kept high to guarantee the oil remains thin enough for efficient low-temperature cold starts, yet robust enough to maintain a protective lubrication film under high operating temperatures. Active phosphorus and sulfur additives form a nanoscale boundary film on steel surfaces, preventing direct metal-to-metal friction during torque spikes.
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. At present, 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.
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. It guarantees the delivery speed and quality of our company to a great extent.
The company has passed ISO-9001-2015 quality system certification, 14001 environmental management system certification, 18001 health management system certification. Automatic transmission Mercedes-Benz certification has laid the foundation for the healthy development of the company and the stability of product quality. The company strictly follows international standards and introduces foreign production processes and testing technologies to ensure that the products can still perform excellently under extreme working conditions, helping customers improve equipment efficiency and reduce maintenance costs.
The rise of Hybrid Electric Vehicles (HEVs) requires specialized E-CVT fluids. These gearboxes combine mechanical gears with integrated electric motors. Thus, the fluid is in direct contact with electrical components, requiring excellent insulating properties and high dielectric strength to prevent current leakage. Additionally, hybrid transmissions experience rapid temperature fluctuations, demanding exceptional thermal-oxidative stability to prevent deposit formation on hot copper coils.
Shandong Longhai is actively developing renewable and bio-based lubricants. By integrating high-performance synthetic esters and eco-friendly additive packages, our next-generation transmission fluids reduce carbon footprint while maintaining performance. This alignment with EU REACH regulations and international environmental mandates ensures our global exporters meet all sustainability requirements.
