Automotive hub unit bearings are integrated transmission components for automobile hubs. Based on traditional automotive hub bearings, they integrate components such as hubs, flanges, and sensors (for some models), serving as precision integrated assemblies with an "all-in-one" design, widely used in the hub systems of modern automobiles.

Core Composition and Advantages

Integrated Design: Combine bearing inner/outer rings, rolling elements, sealing structures, mounting flanges, and even ABS rings (for anti-lock braking system signal collection) into a single unit, reducing assembly steps.

Easy Installation: No additional accessories required; directly fixed to the axle or suspension via bolts, greatly simplifying the vehicle assembly process and improving assembly efficiency.

More Stable Performance: Boast superior sealing performance to effectively prevent dust, water, and sand intrusion. Built-in long-acting grease enables lifelong maintenance-free operation, adapting to complex driving conditions.

Core Functions

Bearing Dual Loads: Simultaneously withstand radial loads from the vehicle body weight and axial loads generated during steering and braking.

Ensuring Precise Transmission: Support stable rotation of wheels, reduce friction loss, and provide wheel speed signals for the ABS system (for sensor-equipped models) to ensure driving safety.

Adapting to Diverse Scenarios: Suitable for various vehicle types including passenger cars, SUVs, and new energy vehicles, acting as a key core component that affects vehicle handling, quietness, and driving safety.
