Our premium Wheel Hub Bearing is a critical safety component, meticulously engineered to OE specifications for a perfect fit and seamless performance. It integrates the wheel hub and bearing into a single, pre-assembled and pre-adjusted unit, ensuring optimal wheel rotation while supporting vehicle weight and handling lateral forces.
Manufactured from high-grade steel and featuring advanced roller bearing technology, it delivers exceptional durability, reduces friction, and maintains precise ABS/EBS sensor signal accuracy. Rigorously tested to exceed ISO 9001 & IATF 16949 standards, each unit undergoes stringent quality checks for run-out tolerance (<0.05mm) and longevity. This guarantees quiet operation, reliable ABS braking system integration, and extended service life, restoring your vehicle's original safety and handling characteristics.
Our hub assembly comes pre-equipped with a high-precision magnetic encoder and sensor. This ensures flawless signal transmission to your vehicle's ABS and traction control systems, which is critical for safe braking and stability control. The sensor is sealed against moisture and contaminants, guaranteeing long-term reliability and accurate wheel speed data, helping to prevent dangerous system failures and ensure passenger safety.
Manufactured from high-grade, forged chrome steel and featuring advanced low-friction roller bearings, our hub is built to withstand extreme loads and harsh driving conditions. It is pre-packed with high-temperature, waterproof grease designed for a lifetime of service, significantly reducing wear. Rigorous testing confirms a service life exceeding 150,000 kilometers under normal driving conditions, providing outstanding value and reliability.
Each unit is a complete, pre-assembled hub and bearing module, meticulously engineered to exact OE dimensions and specifications. This eliminates the complex and risky process of individually pressing bearings and setting tolerances. The result is a perfect fit that ensures optimal performance right out of the box and drastically reduces installation time, making it a preferred choice for professional technicians and DIYers alike.
Every hub bearing undergoes 100% quality inspection and is certified to meet stringent IATF 16949 international automotive quality standards. Critical parameters like run-out tolerance are kept under 0.05mm to ensure smooth, vibration-free rotation and prevent premature wear on adjacent components like brakes and tires. This commitment to quality guarantees a product you can trust for your vehicle's safety.

Here are specific application scenarios of wheel hub bearing:
Suitable for urban road conditions of 30-50 kilometers per day, facing frequent start stop and low-speed steering, relying on the durability of L10 rated life ≥ 1.5 million kilometers under ISO 16281 standard, and equipped with IP6K9K dustproof and waterproof design, it can reduce faults caused by sediment intrusion and meet the annual usage needs of ordinary car owners of 20000 to 30000 kilometers.
For high-speed driving conditions with a speed of 120-180km/h, the maximum allowable speed of 3000-6000rpm and the stability of ECE R122 certification can avoid performance degradation caused by high-speed operation heating. Combined with a double row angular contact structure, it can effectively withstand radial loads and ensure the safety of continuous long-distance driving of more than 500 kilometers.
Coping with muddy, gravel and other road conditions, with a 72 hour salt spray test (G3 level) and ISO 16750 vibration resistance standard, it can resist erosion and bumps from mud and water. Fluororubber seals prevent grease leakage and are suitable for an average annual usage intensity of 15000 kilometers on rural roads, reducing maintenance frequency.
In the cold winter of -40 ℃ in the north or the scorching heat of 120 ℃ in the south, relying on the wide temperature range working performance and the temperature resistance characteristics of S53C carburizing steel, it can avoid low-temperature lagging and high-temperature deformation problems, meet the extreme environment adaptation requirements of the automotive industry, and ensure normal use in different climate regions throughout the year.
For household modified cars with axle loads of 1.5-2 tons, the basic rated dynamic load of 50-150kN can withstand the additional weight after modification. The high wear resistance of SUJ2 steel rolling elements is suitable for mild performance upgrade requirements, and it is also compatible with ABS signal output, which meets the safety certification standards for modified cars and balances performance and compliance.
Construction should be carried out in accordance with ISO/TS 16949 standard, and the tightening torque of bolts should be controlled at 25-45N · m (depending on the vehicle model). Overloading can damage bearings and loosening can cause abnormal noise. After installation, check that the axial displacement is ≤ 0.05mm to ensure compliance with ECE R122 safety requirements and avoid potential driving hazards.
Pay attention to any abnormal noise from the bearings every 5000 kilometers, and do not use high-pressure water to directly flush the seals during cleaning (although it has IP6K9K protection, it still prevents extreme impact). If the hub temperature is greater than 60 ℃, the machine needs to be stopped for inspection, and assistance should be provided to maintain the L10 rated life of ≥ 1.5 million kilometers.
When replacing, it is necessary to match the axle load of the vehicle model (0.5-2 tons), and the new bearings should avoid direct contact with oil stains. After installation, a no-load rotation test is required, with a torque fluctuation of ≤ 1.5N · m, in compliance with QC/T standards, to ensure that the performance meets the standards after replacement.
