In the complex architecture of modern automotive engineering, the differential fluid (often referred to as gear oil) serves as the lifeblood of the drivetrain system. As vehicles evolve with higher torque outputs and more demanding duty cycles, the role of premium lubrication in preventing friction-induced wear, dissipating thermal energy, and ensuring smooth power distribution between wheels has never been more critical. Chinese manufacturers, led by industry pioneers like Zhejiang DC-Link Auto Co., Ltd., are at the forefront of this chemical and mechanical revolution.
Our fluids are engineered to withstand extreme temperatures ranging from -40°C to 150°C, ensuring viscosity retention and component protection in diverse climates.
Advanced sulfur-phosphorus EP (Extreme Pressure) additives form a resilient protective layer on gear teeth, preventing pitting and scoring under heavy loads.
With the rise of Electric Vehicles, our R&D focus has shifted to low-conductivity fluids that provide superior cooling for integrated e-axles and high-speed reducers.
