Core features highlight product strength
Ultra-low friction loss
*Using a new PTFE low-friction composite lip material, the starting friction torque is controlled to <1 in·lb, greatly reducing energy consumption and heat generation
*Optimizing the lip geometry curve design, taking into account both sealing and lubrication, greatly improving the free rotation efficiency of the hub motor
01
Wide temperature range weather resistance
*The main elastomer material uses HNBR + FKM two-component composite formula, and the operating temperature range extends from -40 ℃ to +200 ℃
*It has excellent tolerance to acids, alkalis, oils and various chemical media, ensuring long-term leakage-free in extreme environments
02
Integrated high-strength structure
*Multi-lip composite structure plus aluminum alloy shell is formed in one piece, which not only enhances two-way protection, but also takes into account heat dissipation and installation convenience
*Combined with precision injection molding and stamping technology, the lip and frame fusion interface is flawless
03
Ultra-high life and reliability
*In the 1,000 h continuous endurance test, the PN value (leakage) is always maintained below 0.02 mg/min
*Vibration resistance and impact resistance have passed the rigorous test of ISO 16750-3, and the service life is increased by 30% compared with the same level products in the industry

Full-process quality control to create "zero defect" production
In each link of design, procurement, production, testing, packaging and transportation, NNK factory strictly implements systematic and standardized quality control processes:
Front-end design control: Professional review is initiated from the product concept stage to ensure that the sealing structure, material formula and performance indicators of the wheel hub oil seal fully meet the terminal requirements;
Multiple testing and verification: Precision hardness tester, laser profiler and medium leakage tester are used to cover the four core indicators of hardness, thickness, geometric tolerance and leakage to ensure that each product meets the standards;
Packaging and transportation escort: Moisture-proof and anti-collision packaging solutions are used, combined with dynamic scanning code tracking to ensure that the product can be traced from the factory to the customer's hands and delivered without loss.
Through the above strict links, NNK truly achieved the goal of "zero defect" in the production process, so that each wheel hub oil seal can withstand the rigorous test of customer sites and laboratories.
