This professional-grade wheel hub bearing is engineered for exceptional durability and precise performance. Manufactured from high-carbon chromium steel under IATF 16949 quality standards, it ensures superior strength and resistance to wear. The unit features an advanced triple-lip sealing system and premium grease, providing reliable protection against contaminants and offering a quiet, smooth operation.
Rigorously tested to support dynamic loads up to 8.5 kN and exceed 100,000 kilometers under normal conditions, this bearing guarantees long-term reliability. It comes with an integrated ABS sensor ring for accurate speed signal transmission and safe braking performance. Ideal for replacement and maintenance, this product delivers OEM-quality fit and function for a secure and comfortable driving experience.
Crafted from premium GCr15 bearing steel, our hub bearings undergo precise heat treatment to achieve a core hardness of 59-65 HRC. This ensures exceptional resistance to wear and fatigue, extending the product’s service life beyond 100,000 kilometers under normal driving conditions. Rigorous load testing confirms dynamic load capacity of 8.5 kN and static load support of 45 kN, providing reliable performance even under demanding conditions.
Equipped with a triple-lip sealing structure and high-performance grease, our bearings achieve an IP6K9K protection rating, effectively blocking moisture, dust, and corrosive contaminants. Salt spray testing exceeding 400 hours guarantees corrosion resistance, making this unit ideal for diverse road and climate conditions.
Computer-balanced internal components minimize vibration and noise levels below 65 dB during operation. The precisely manufactured ABS encoder ring ensures accurate wheel speed signal transmission, enhancing compatibility with anti-lock braking and stability control systems for safer driving.
Every unit is manufactured in an IATF 16949:2016 certified facility and subjected to 100% quality inspections, including torque accuracy, radial runout (≤0.03mm), and ABS signal functionality. Compliant with CE and RoHS standards, our bearings meet international requirements for performance and environmental safety.
Designed to match original specifications, our bearing units enable seamless replacement without modifications. Pre-assembled construction and optimized bolt torque settings reduce installation time and minimize errors, making them a preferred choice for professional workshops and fleet services.
Engineered to withstand high radial and axial forces, the bearing maintains structural integrity under extreme stress. The hardened inner and outer rings, combined with precision-ground rollers, ensure stable performance at speeds ranging from -40°C to 120°C, contributing to vehicle safety and reduced maintenance needs.

Here are specific application scenarios of wheel hub bearing:
For optimal performance, we recommend professional installation. Securely lift and support the vehicle before removing the worn assembly. Clean the mounting surface thoroughly to ensure proper contact. Torque the central nut to 180-220 N·m using calibrated tools to prevent overload. Always reconnect the ABS sensor securely and conduct a test drive to verify noise elimination and ABS functionality. Consult official repair manuals for specific procedures.
