It maintains a tight, concentric seal around the rotating shaft, ensuring stable ABS sensor readings and prolonging the life of hub components. Made from high-performance elastomer and supported by a reinforced metal casing, this seal withstands extreme heat, rotational speed, and continuous vibration. Its optimized lip design provides consistent sealing pressure, reducing wear and ensuring long-term reliability.
By preventing dirt, moisture, and debris from reaching the ABS sensor zone, the sealing ring helps maintain accurate wheel speed detection and enhances braking safety. It also minimizes friction, reduces maintenance costs, and ensures smooth, trouble-free vehicle operation even under harsh road and climate conditions.
