    Sealed Design

    ZZ sealed structural design protects internal components against contaminants and prevents premature wear.

    Engineering & Application Details

    Structural Features

    DAC458242 ABS bearings are angular contact ball bearings capable of bearing combined radial and axial loads. The specific contact angle determines the axial load capacity and maximum speed profile: a larger contact angle enhances axial capacity while balancing maximum permissible operating speed.

    Application Areas

    A critical component in the automotive wheel hub assembly, it provides rotation support while withstanding dynamic vehicle weight, road impacts, and braking forces. The integrated ABS signal generator transmits accurate wheel speed data to ABS and ESP systems for superior driving stability.

    Installation & Maintenance

    Proper lubrication minimizes friction and maximizes operating speed. Compatible with grease or oil lubrication. Ensuring proper grease viscosity prevents overheating and speed limitation, while stable oil supply guarantees optimal thermal dissipation.

    Special ABS Design

    Engineered with integrated ABS tone rings/sensors, this unit is calibrated to keep rotational inertia low. The bearing maintains speed uniformity within operating limits to guarantee that ABS sensors capture real-time wheel velocity accurately.

    Frequently Asked Questions
    What are the primary dimensions and specifications of the DAC458242 bearing?
    The DAC458242 bearing has an inner diameter of 45 mm, an outer diameter of 82 mm, and a width of 42 mm (45*82*42 mm). It weighs approximately 0.9 kg and features a double-row angular contact structure.
    What material is used in manufacturing this wheel hub bearing?
    It is manufactured from premium Chrome Steel (GCr15), heat-treated to a hardness level of HRC61 - 65, providing superior wear resistance and structural stability under harsh road conditions.
    How does the integrated ABS sensor enhance vehicle safety?
    The built-in ABS sensor/encoder accurately measures wheel rotation speed and transmits real-time data to the vehicle's Anti-lock Braking System (ABS) and Electronic Stability Program (ESP), preventing wheel lockup during abrupt braking.
    Which vehicle makes and positions is this bearing compatible with?
    The DAC458242 bearing is designed for Ford vehicles, primarily utilized in the front wheel hub assembly to ensure smooth rotation and precise braking control.
    What customization options are available for this bearing?
    Customizations include precision grades (P0, P2, P4, P5, P6), internal clearances (C0 to C5), cage materials (brass, steel, nylon), vibration ratings (Z1V1 to Z4V4), and customized commercial packaging options.
    What lubrication methods are recommended for optimal performance?
    Grease lubrication and oil lubrication can both be used. Selecting the correct grease viscosity and ensuring adequate lubrication avoids friction, reduces operational heat, and sustains higher rotational speeds.
