💡 What is a wheel hub assembly with sealed ball bearing used for? A wheel hub assembly supports the wheel, enables rotation and houses the sealed bearing for low-maintenance operation. - Carries vehicle load and transfers braking and driving forces while keeping the wheel aligned and stable. - Sealed ball bearing reduces contamination and upkeep, improving service life and noise control; ceramic options are available for racing/high-temp use. - Integrates ABS tone ring signals for wheel speed sensors and provides a direct OE fit replacement like OE513188 for many 6-lug front axle setups.
