Product Advantage
1. Superior Load Capacity & Extended Service Life
Engineered for exceptional durability, our wheel bearing is constructed from premium CRB anti-fatigue steel. It undergoes rigorous simulated life cycle testing, demonstrating a capability to withstand axial loads of over 4.8 kN and radial loads exceeding 3.2 kN. This robust construction ensures a reliable service life surpassing 100,000 kilometers, providing peace of mind and reducing long-term ownership costs. The advanced heat treatment process further enhances its resistance to deformation under extreme stress and temperature variations.
2. Advanced Sealing Technology for Maximum Contaminant Protection
The heart of our bearing's reliability lies in its innovative triple-lip contact seal design. This seal is engineered from high-grade NBR (Nitrile Rubber) compounds, offering superior resistance to water, salt, mud, and abrasive brake dust. Independent lab tests confirm over 500 hours of salt spray resistance without failure. This robust sealing system effectively retains high-temperature grease, ensuring consistent lubrication, quiet operation, and protecting the internal components from premature wear, even in the most challenging driving environments.
3. Precision-Engineered for Accurate ABS Signal & Smooth Operation
Safety and performance are paramount. Our wheel bearing features a magnetically encoded encoder ring that is integrally molded, ensuring flawless and consistent ABS and ESC signal transmission. This eliminates signal dropout and ensures your vehicle's safety systems function as intended. Furthermore, our proprietary micro-geometry optimization on the ball tracks and races minimizes vibration and noise, resulting in a remarkably quiet and smooth ride that meets OE-level NVH (Noise, Vibration, and Harshness) standards.
4. Rigorous Quality Assurance & Direct OEM Replacement
Every unit is manufactured in our IATF 16949:2016 certified facility, guaranteeing a world-class quality management system. We employ 100% run-out and torque testing on the production line to ensure perfect concentricity and smooth rotation. As a direct OEM-fit replacement, this hub assembly guarantees perfect compatibility with your vehicle's original mounting points and CV joints, allowing for a hassle-free installation with no modifications required, saving you both time and labor costs.

Product Uses
Here are specific application scenarios of wheel hub bearing:
1. For Daily Commuting & Urban Driving
Navigate stop-and-go traffic and paved city roads with confidence. Our wheel bearing is designed to handle the constant stress of frequent acceleration, deceleration, and turning. The precision-ground components and advanced lubrication ensure exceptionally quiet operation, eliminating the low-frequency hum that often develops in worn bearings, thereby enhancing your daily driving comfort.
2. For Demanding Road Conditions
Engineered for resilience on poorly maintained roads, construction zones, or routes with frequent potholes and speed bumps. The unit's robust construction, with a dynamic load rating exceeding 48 kN, effectively absorbs and distributes impact forces. This protects your vehicle's suspension components and prevents premature failure, ensuring dependable performance where it matters most.
3. For Long-Distance Highway Driving
Maintain stability and safety during extended high-speed travel. The bearing's ultra-low runout tolerance (≤ 0.05 mm) and optimized internal geometry minimize vibration, providing a smooth and stable ride. The integrated ABS encoder ensures your vehicle's safety systems function flawlessly, offering critical protection during emergency maneuvers or in adverse weather conditions.
4. For Harsh Weather & Corrosive Environments
Built to withstand the challenges of rainy, snowy, and salt-spray environments. The triple-lip seal with HNBR material provides an IP6K9K level of protection, effectively blocking out moisture, road salt, and abrasive contaminants. This superior sealing technology is crucial for preventing grease wash-out and internal corrosion, which are primary causes of bearing seizure and failure.
5. As a Proactive Maintenance & Safety Upgrade
Replace worn components before they lead to costly repairs or safety hazards. Installing our premium wheel bearing as part of routine maintenance restores like-new handling and eliminates warning signs like play in the wheel or abnormal tire wear. It is a direct-fit, reliable solution that ensures the accurate operation of your ABS and stability control systems.
Product Operate Guide
To ensure optimal performance and safety, correct installation is crucial. We recommend using a hydraulic press and certified tools to avoid damaging the bearing. Always tighten the central hub nut to the specified torque (170-190 N·m) using a calibrated torque wrench. After installation, perform a road test at low speed, checking for any unusual noises or vibrations to confirm a successful fit. For your safety, always refer to a professional service manual.
