1014003295 High-precision OEM-grade Vehicle-specific Wheel Hub Bearing for Geely KingKong

1.Double-Row Angular Contact Structure, 40% Higher Load-Bearing Capacity

The Geely Wheel Hub Bearing with double-row angular contact design can bear both radial and axial loads simultaneously, with a rated dynamic load of 28kN, which is 40% higher than that of ordinary single-row bearings. Tested in accordance with German DIN 72204 standard, its load stability retention rate exceeds 95% under simulated complex road conditions, capable of adapting to load-bearing needs in different driving scenarios. It is a core technical highlight of the high-reliability Geely Wheel Hub Bearing.

2.Vacuum Carburizing Process, Surface Hardness Up to HRC62-64

The inner and outer rings adopt vacuum carburizing heat treatment process, with surface hardness precisely controlled at HRC62-64 and core toughness maintained above 1200MPa, effectively solving the industry problem of "high hardness and easy brittleness". Third-party testing shows that this process reduces the bearing wear to ≤0.001mm per 100,000 kilometers, laying a foundation for the Geely Wheel Hub Bearing to achieve a long service life of 150,000 kilometers.

3.IP69K Protection Level, No Rust After 1000-Hour Salt Spray Test

Each Geely Wheel Hub Bearing is equipped with multi-layer fluororubber sealing rings, reaching IP69K protection level, which can resist high-pressure water flushing and sand intrusion. After 1000 hours of neutral salt spray test, there is no rust on the components, far exceeding the industry's conventional 500-hour standard. This feature reduces the failure rate of the product by more than 60% when used in rainy and dusty areas.

4.Integrated Sealing Design, Grease Leakage Rate < 0.01%

Innovatively adopting an integrated sealing structure, combined with high-stability lithium-based grease, the grease sealing performance is significantly improved, and the leakage rate is controlled at < 0.01%. After 100,000 revolutions of high-speed rotation test, the grease retention rate still reaches more than 98%, no need for intermediate grease replenishment, reducing later maintenance costs. It perfectly meets the long-term use needs of high-precision Geely Wheel Hub Bearing.

5.Compliant with ISO/TS 16949 Certification, 100% Factory Qualification Rate

All Geely Wheel Hub Bearings are produced in accordance with the ISO/TS 16949 automotive industry quality standard. 30% of each batch is randomly selected for 12 tests including dynamic balance and vibration noise, and the factory qualification rate is stably maintained at 100%. At the same time, it has passed Geely's original factory technical verification to ensure high compatibility with the original vehicle system, making it the first choice for replacing high-precision Geely wheel hub bearing in the after-sales market.

1.High-Frequency Urban Commuting Scenario

Suitable for the needs of frequent starts/stops and low-speed steering on urban roads. Its rotational accuracy of ≤0.005mm can reduce wheel wobble, and the high rotational speed of 6500r/min adapts to driving on urban expressways. Statistics show that the product can reduce driving noise by 35% in this scenario, and with long-life grease, it meets the long-term use needs of 2-4 hours of daily commuting.

2.Complex Road Condition Driving Scenario

In scenarios such as mountain roads and suburban unpaved roads, the high rated dynamic load of 28kN can stably bear bump impacts, and the IP69K protection level blocks sand, mud and accumulated water. Third-party tests show that the product failure rate is 50% lower than that of ordinary bearings under complex road conditions, ensuring driving stability in harsh environments.

3.Extreme Climate Adaptation Scenario

It can operate stably at extreme temperatures of -40℃~120℃. The grease does not solidify in low-temperature environments, and the seal meets temperature resistance standards in high temperatures. When used in frigid and tropical regions, the product life retention rate reaches more than 90%, adapting to the use needs of multiple climate regions around the world.

4.After-Sales Maintenance Replacement Scenario

As a core after-sales replacement part, its precise installation tolerance of H7/js6 can reduce installation and commissioning time by 80%, and the long service life of 150,000km reduces the frequency of repeated replacements. Currently, it has become a designated replacement part for more than 150 auto parts maintenance providers worldwide, meeting the after-sales market's demand for "high compatibility and long durability".

1. Installation Key Points

   
   

   Clean the mating surfaces of the shaft and bearing before installation to ensure no impurities (according to after-sales data, 60% of installation failures are caused by impurities); assemble strictly in accordance with H7/js6 tolerance to avoid over-tightening or over-loosening. It is recommended to use a torque wrench to fix according to the standard torque to ensure compatibility.

2. Usage Precautions

   
   

   Avoid long-term overloaded driving (do not exceed the rated dynamic load of 28kN) to prevent premature bearing wear; check immediately if abnormal noise or vibration is found, which can reduce the risk of serious failures by 70% and ensure driving safety.

3. Daily Maintenance

   
   

   Check the integrity of the seal every 50,000 kilometers and replace it in time if damaged (dust-proof failure will shorten the service life by 50%); there is no need to add grease frequently, and it can be replaced at the 150,000-kilometer cycle under normal use to reduce maintenance costs.
