Product Description

Automotive Wheel Hub Bearing Unit VKBA7447 Overview

The VKBA7447 wheel hub unit is a precision-engineered automotive component tailored for mid-size passenger cars and light commercial vehicles. Integrating high-grade ball bearings, a forged steel hub, and dual-lip sealing, it delivers a dynamic load capacity of 2,800 lbs and max rotational speed of 6,500 RPM, ensuring smooth power transfer. Crafted via advanced heat treatment and CNC machining, it offers exceptional wear resistance and corrosion protection, thriving in extreme temperatures (-40°C to 120°C) and wet/dusty road conditions. The unit's precise dimensional accuracy (OD: 100mm, ID: 45mm) enables tool-free, direct-fit installation.

Automotive Wheel Hub Bearing Unit VKBA7447 Feature

1. Integrated Compact Design Integrates bearing, flange, and seal into one pre-assembled unit, simplifying installation, reducing wheel-end space occupation, and avoiding assembly errors.

2. Strong Combined Load Capacity Optimized angular contact structure bears heavy radial loads (vehicle weight) and bidirectional axial loads (cornering/braking), withstanding sudden road impacts stably.

3. Excellent Sealing & Durability Equipped with multi-layer rubber lip seals and metal dust covers, it effectively blocks water, dust, and road salts, preventing lubricant leakage and internal corrosion.

4. Low-Noise & High Precision Precision-machined raceways and high-quality steel rolling elements minimize friction; advanced lubrication technology ensures low rotational noise and long service life (up to 150,000+ km).

Automotive Wheel Hub Bearing Unit VKBA7447 Applications

1. Passenger Cars Matched to compact and mid-size passenger cars (e.g., hatchbacks, sedans), serving as front/rear wheel hub bearings, ensuring smooth driving and ride comfort.

2. Light Commercial Vehicles Applied in light vans, mini-trucks, and MPVs, adapting to frequent start-stop and moderate load changes in urban logistics or passenger transport.

3. New Energy Vehicles (NEVs) Suitable for small electric cars and plug-in hybrids, with low-friction design reducing energy consumption and matching electric drivetrain requirements.

4. Special Light Vehicles Used in light modified vehicles like urban electric logistics vehicles and small recreational vehicles, meeting wheel-end reliability needs in specialized scenarios.
