Wheel Hub Bearing DAC42840040 (2).jpg

China DAC42840040 Wheel Hub Bearing 42*84*40 - High Precision Automotive Front Bearing Suppliers & Factory

High Load-Bearing Capacity: Our bearings are engineered to efficiently support both the weight of the vehicle (radial load) and the lateral forces encountered during cornering and braking (axial load). This ensures optimal performance for your vehicles.

Dynamic Stability: The design of our bearings is tailored to withstand shocks and vibrations from varied road conditions, such as bumpy surfaces and emergency braking situations, providing a reliable driving experience.

Low Friction Coefficient: Utilizing top-quality materials and advanced processing technology, our bearings exhibit a low friction coefficient between the rolling elements and raceways. This results in smoother wheel rotation, significantly reducing energy consumption and enhancing fuel economy.

As a leading China bearing supplier with a modern factory, we are committed to delivering high-performance solutions tailored to meet the demands of the automotive industry.

    Key Performance Characteristics

    High Load-Bearing Capacity

    Engineered to support both heavy radial loads (vehicle static/dynamic weight) and bidirectional axial loads during cornering and braking maneuvers.

    Dynamic Stability

    Optimized structure effectively absorbs shocks and severe road vibrations under rough conditions, potholed surfaces, and emergency stops.

    Low Friction Coefficient

    Precision raceway superfinishing reduces friction between rolling elements and raceways, lowering rolling resistance and boosting vehicle fuel economy.

    High Rotation Precision

    Maintains superior coaxiality and runout accuracy of the wheel hub assembly, minimizing driving vibration, noise, and uneven tire wear.

    Exceptional Reliability

    Manufactured from vacuum-degassed GCr15 chrome steel with advanced heat treatment for optimal surface hardness, core toughness, and wear resistance.

    Structural Features

    Double-Row Architecture

    Constructed as a double-row angular contact ball or tapered roller assembly, providing enhanced structural rigidity and bidirectional thrust tolerance.

    Advanced Seal Design

    Utilizes high-integrity double-lip or composite seal configurations to lock in premium grease while blocking external water, mud, and abrasive contaminants.

    High System Integration

    Designed to integrate seamlessly with modern vehicle sensors, encoder magnetic impulse rings, and ABS modules for precise wheel speed detection.

    Vehicle Applications & Installation

    Widely Applicable Models

    Commonly applied across passenger cars, commercial fleet utility vehicles, and economy platforms including Foton Midi, Great Wall Mini, Fengxing S500, Jingyi X3/X5, and equivalent hub assemblies.

    Easy Installation & Maintenance

    Unitized bearing construction fits directly onto hub carriers and shafts, eliminating complex clearance adjustments, shortening downtime, and reducing maintenance overhead.
