1064001293 Durable High-performance Precision-engineered Wheel Hub Bearing for Geely EC-7

1.High-Wear-Resistant Material for Extended Service Life

Made of GCr15 high-carbon chromium bearing steel, its surface hardness reaches HRC 60-62 after carburizing and quenching, which improves wear resistance by 30% compared with ordinary bearing steel. It has passed a 1200-hour salt spray test without rust, adapting to the complex working conditions of Geely vehicles. This effectively solves the problems of easy wear and short service life of Geely Wheel Hub Bearing and meets the ISO 15243 automotive bearing quality standard.

2.Precision Structural Design for Reduced Operating Noise

Equipped with a double-row angular contact ball structure, the radial runout is controlled within 0.005mm. Combined with nitrile rubber (NBR) seals, it achieves an IP68 dust and water resistance rating. The measured noise is only 45dB at a rotation speed of 600r/min, which is 8dB lower than the industry average, providing users with a quiet driving experience. This is a core advantage of high-quality Geely automotive bearings.

3.High Load-Bearing Capacity for Multi-Scenario Adaptation

The rated dynamic load reaches 28kN and the rated static load is 42kN, which can withstand the instantaneous impact load during vehicle start-up and braking. It has passed the extreme temperature cycle test from -40℃ to 120℃ with stable performance, adapting to multi-scenarios such as urban commuting and long-distance driving. It fully complies with the technical parameters of Geely original Wheel Hub Bearing.

4.Original Factory Compatible Design for Simplified Installation Process

Adopting the same dimensional tolerance as Geely original factory (outer diameter error ±0.02mm, inner diameter error ±0.01mm), no modification to the installation structure is required, and even beginners can complete the replacement within 30 minutes. Each batch of products has passed the installation test of Geely main engine factory, achieving 100% compatibility with all Geely vehicle models and avoiding the installation and adaptation problems of Geely Wheel Hub Bearing.

1.Urban Daily Commuting Scenarios

Suitable for urban road conditions with frequent starts/stops and low-speed driving. With a radial runout accuracy of ≤0.005mm, it reduces wheel operation resistance. Combined with IP68 protection level, it can cope with rainy water accumulation and dusty environments in cities. Tested to have a stable service life of 80,000km under a daily commuting intensity of 50km, complying with the ISO 15243 durability standard.

2.Long-Distance High-Speed Driving Scenarios

It can bear continuous loads under high-speed operation of 600r/min, and the 45dB low-noise feature improves long-distance driving comfort. The wide temperature adaptation range of -40℃~120℃ can handle day-night temperature differences in different regions, meeting the reliability requirements of long-distance cross-regional driving. It has passed the long-distance road condition test verification by Geely's original factory.

3.Complex Road Condition Driving Scenarios

For bumpy road conditions such as unpaved roads and mountain roads, the rated dynamic load of 28kN and rated static load of 42kN can resist instantaneous impacts. The high wear resistance of GCr15 steel material reduces losses caused by gravel impact. The 1200-hour salt spray test ensures corrosion resistance in humid mountainous areas and coastal sections, making it suitable for use in multiple complex environments.
