Adopting SUJ2 high-purity bearing steel, treated with 1200℃ vacuum quenching, the hardness reaches HRC62-64, far exceeding the industry standard of HRC58-60. Laboratory data shows that in a 2000-hour simulated road condition test, the wear amount is only 0.03mm, and the service life is increased by more than 50% compared with ordinary bearings. As a supplier with 18 years of experience in the auto parts industry, our strict material selection ensures that every Chery Wheel Hub Bearing can cope with complex road conditions.
Innovatively adopting a dual-seal design of double-lip nitrile rubber seal + metal dust cover, it has passed the authoritative IP69K waterproof and dustproof certification (capable of withstanding 80℃ high-pressure water jet). Actual tests show that after 6 months of use in muddy and heavy rain environments, the interior of the bearing remains dry and clean, effectively avoiding abnormal noise and jamming caused by impurity intrusion, and ensuring the stable operation of the Wheel Hub Bearing.
Some models are built with imported Hall-effect ABS sensors, and the wires are made of fluororubber material resistant to 150℃ high temperature. The signal transmission delay is ≤0.02 seconds, and the accuracy reaches 99.8%. It has passed the ISO/TS 16949 automotive industry quality system certification, and is perfectly compatible with Chery's original vehicle system. It can feed back wheel speed in real time, providing accurate data support for driving safety, which is a core highlight of the high-quality Chery Wheel Hub Bearing.
Using Japanese OKUMA CNC lathes for precision machining, the tolerance of key dimensions (such as inner ring bore diameter, outer ring diameter) is controlled within ±0.005mm, far higher than the industry standard of ±0.01mm. Each batch of products undergoes 3 full-dimensional inspections and 1 dynamic balance test (balance accuracy up to G2.5 level), ensuring no eccentric vibration after the Wheel Hub Bearing is installed, reducing vehicle driving noise and improving driving comfort.
Relying on a 100,000㎡ modern production base and a complete quality control system, we provide a 80,000km or 1-year warranty for all Chery Wheel Hub Bearings (whichever comes first). Customer feedback data shows that the product defect rate is only 0.08%, lower than the industry average of 0.3%. The after-sales team provides 24-hour online response, and if return or exchange is needed, you can enjoy fast processing service within 7 days, making procurement more assured.

Here are specific application scenarios of wheel hub bearing:
Suitable for urban road conditions with frequent starts/stops and low-speed turns. Tested to operate stably for 80,000 km without abnormalities under a daily commuting intensity of 30 km. The dual-seal structure resists rainwater accumulation and road dust in cities, preventing bearing failure caused by impurity intrusion, and meets the basic reliability requirements for Wheel Hub Bearing in daily commuting.
Designed for long-distance heavy loads (50% additional load per trip), with a dynamic load rating of 90 kN, capable of withstanding radial pressure during 12 hours of continuous high-speed driving. Actual tests show that for long-distance transport vehicles using this bearing, the fault interval is 60% longer than that of ordinary products, reducing maintenance costs during freight transportation.
The bearing grease maintains good fluidity at -40℃, avoiding cold-start jamming; at +150℃, the seals show no aging or deformation. Verified through extreme cold (Siberian test site) and high-temperature (Middle East desert test) tests, ensuring the normal operation of Chery Wheel Hub Bearing in extreme climates.
As an original-equipment compatible replacement part, the precision machining with a dimensional tolerance of ±0.005 mm ensures 100% installation compatibility. Maintenance data shows that after installing this bearing, the vehicle secondary maintenance rate is only 0.5%, far lower than the industry average of 1.8%, providing an efficient and reliable replacement solution for maintenance providers.
Check that the bearing surface is free of scratches and the seals are intact. Clean the installation area (impurity residue must be ≤0.01g). Use a torque wrench to fasten according to the standard of 55-70N·m to avoid abnormal noise or damage caused by loose or over-tightening.
Inspect the bearing for leakage and abnormal noise every 5,000km, and measure the vibration value with professional equipment (must be ≤1.5mm/s). After use in extreme environments, clean the surface sediment in time to extend the service life.
If the rotation speed decreases or the temperature exceeds 80℃, stop the machine immediately for inspection and do not use it forcibly. When replacing, you need to match the same model of Chery Wheel Hub Bearing to ensure compatibility and safety.
