Our Geely Wheel Hub Bearing is engineered for exceptional durability and precise performance, meeting strict OEM standards. Constructed from high-grade steel and advanced sealing technology, it ensures extended service life (tested for over 100,000 km) and reliable operation under heavy loads and extreme conditions.
With high-precision manufacturing and rigorous quality validation (ISO 9001, IATF 16949 certified), this hub bearing reduces friction, noise, and vibration while enhancing vehicle safety and fuel efficiency. It integrates seamlessly with ABS and ESP systems, providing stable braking and steering control.
Ideal for replacement markets, our product guarantees perfect fitment, superior corrosion resistance, and optimal heat dissipation. Trusted by professionals worldwide, it delivers unmatched performance and value for modern automotive systems.
Engineered for exceptional longevity, our Geely Wheel Hub Bearings are constructed from ultra-high-grade, heat-treated chromium steel. This material significantly enhances tensile strength and fatigue resistance, supporting dynamic loads exceeding 4,500 kg. Rigorous endurance testing under extreme conditions confirms a service life surpassing 100,000 kilometers. This exceptional durability translates to fewer replacements, reduced downtime, and higher customer satisfaction, making it a reliable and profitable choice for your inventory.
Our hub bearings feature a state-of-the-art multi-lip sealing system integrated with high-grade HNBR (Hydrogenated Nitrile Butadiene Rubber) seals. This design provides an IP69K rating for superior protection against water, mud, road salt, and abrasive contaminants. Combined with a multi-layer anti-corrosion coating, it guarantees impeccable performance in harsh environments. This technology drastically reduces the risk of premature grease leakage and internal raceway wear, ensuring smooth operation and signal integrity for ABS sensors.
Every bearing is manufactured to exact OEM specifications using CNC precision grinding. This process guarantees micron-level accuracy (P5/P6 precision grade) for perfect fitment, zero play, and seamless integration with ABS and ESP systems. The result is flawless vehicle stability, accurate wheel speed data for braking systems, and a quiet, vibration-free ride. Our commitment to precision ensures perfect installation every time, eliminating comebacks and building trust with your end-users.
The optimized internal geometry and low-friction, high-performance lithium-complex grease reduce rolling resistance by up to 30% compared to standard bearings. This reduction in friction contributes to improved fuel efficiency and lower CO2 emissions. Furthermore, the precision-ground races and high-quality balls minimize operational noise (below 75 dB even at high speeds), providing a noticeably quieter and smoother driving experience that meets modern vehicle performance standards.
We operate a fully certified IATF 16949:2016 quality management system, ensuring every hub bearing meets the strictest international automotive standards. Each unit undergoes a 100% final inspection, including torque rotation tests, seal integrity checks, and ABS signal validation. Our products are also certified by SGS for material composition and performance. This unwavering commitment to quality guarantees that you are supplying a part that professionals can install with absolute confidence.

Here are specific application scenarios of wheel hub bearing:
For optimal performance and safety, always refer to the vehicle's service manual. Prior to installation, thoroughly clean the hub and axle contact surfaces. Critical: Use a torque wrench to tighten the hub bolt to the specified 180-220 N·m to prevent damage. Avoid any impact on the ABS sensor or magnetic encoder ring during handling. After installation, conduct a short test drive at low speed to verify smooth operation and ensure the ABS/ESP warning lights function correctly. Proper installation guarantees the bearing's 100,000+ km service life.
