This is a third-generation integrated wheel hub bearing assembly, integrating the wheel hub flange, double-row bearing, internal spline, mounting bolts, and seals into one unit. The model shown in the image is compatible with Mitsubishi Pajero V73/V93/V97 off-road SUVs, model number: MR594954 / 3780A011.
The structure includes multiple mounting bolts, an internal spline (for transmitting drive torque), double-layer rubber seals, and factory-filled grease, making it a maintenance-free design.
II. Core Applications
1. Vehicle Load Bearing + Rotation Guidance Bears the weight of one wheel on each side of the vehicle, ensuring smooth and stable wheel rotation, and absorbing radial and axial loads from road bumps.
2. Torque Transmission in Four-Wheel Drive Vehicles The central internal spline engages with the half-shaft spline to transmit power to the wheels, suitable for four-wheel drive off-road vehicles, pickup trucks, and heavy-duty SUVs.
3. Equipped with ABS Sensor (Most models have built-in magnetic ring)
The bearing outer ring integrates a magnetic encoder, providing wheel speed signals to the ABS system to ensure the normal operation of the anti-lock braking function.
4. Compatible Vehicles Primarily used for rear/front wheel replacement in hardcore off-road SUVs such as Mitsubishi Pajero V73/V87/V93/V97 and Pajero Sport, it is also widely compatible with the aftermarket repair services of various passenger cars, pickup trucks, and light trucks.
III. Core Product Advantages
1. Integrated Design for Convenient Installation bearings, hub flanges, bolts, and seals are pre-assembled at the factory, allowing for complete replacement during repairs without the need for separate bearing press-fitting, significantly reducing repair time and increasing repair shop replacement efficiency by 60%.
2. Double-Layer Composite Seal for Waterproof, Dustproof, and Durable Operation Inner and outer double-layer rubber skeleton oil seals + dustproof retaining rings prevent mud, water, and sand from entering the bearing during off-road wading and muddy conditions, making it suitable for SUVs and harsh off-road conditions, extending service life.
3. Pre-filled with long-life grease, maintenance-free: Factory-filled with high-temperature, long-life lithium-based grease, eliminating the need for grease application throughout its lifespan and reducing maintenance costs for vehicle owners.
4. Double-row raceway structure, high load-bearing capacity: The double-row angular contact ball/tapered roller structure simultaneously withstands radial force and bidirectional axial impact, minimizing noise and looseness under heavy off-road loads and bumpy roads, making it suitable for heavy-duty SUVs.
5. High-precision heat treatment, less prone to deformation: Bearing steel raceways and forged wheel hub flanges undergo high-frequency quenching to increase hardness, reducing heat and wear at high speeds, resulting in less vibration and noise.
6. With positioning mounting flange, high assembly precision: The five-hole positioning flange ensures precise alignment of mounting holes, minimizing wheel runout after installation and preventing high-speed deviation and abnormal tire wear.
7. High cost-effectiveness for after-sales replacement: Domestically produced replacements for original parts, priced significantly lower than Japanese original parts, with quality meeting OEM standards, making it a mainstay bearing category for overseas auto parts wholesalers and repair shops.
