Default rubber seal, iron cover seal, no seal, random delivery！

• 1.A key component of the automobile chassis, installed between the wheel hub and the axle, integrating rolling elements and sealing structures, and is responsible for connecting the wheel to the body. It also bears the weight of the body (radial load) and the horizontal force (axial load) generated by steering and braking.
• 2.Transmits power and distributes braking force, supporting the vehicle's weight. Reduces wheel friction, ensuring stable rotation and preventing wheel deviation. Isolates dust, mud, and water, preventing internal grease leakage and extending life.
• 3.Split-type: Commonly used in early models, requires additional components and offers poor sealing and portability. Unit-type: The current mainstream type, integrating bearings and flanges (some with ABS sensors), offers easy installation and strong sealing.
• 4.Fault Signs: Unusual humming noise from the wheels while driving (more noticeable at higher speeds), heavy steering, wheel shaking, or the ABS light illuminates. Maintenance: Maintenance-free design with a lifespan of 80,000-150,000 kilometers. Replacement requires special tools. Ensure the required torque is met and inspect the seals.
