The automotive wheel hub bearings manufacturing process focuses on high-speed reliability and integrated precision. The selected bearing steel undergoes vacuum refining to ensure material purity. The raceways are machined using CNC grinding machines to achieve geometric accuracy of IT4. The flange holes and end faces are CNC machined to achieve a coaxiality of ≤0.01 mm.

The components undergo quenching and tempering followed by cryogenic treatment, achieving a hardness of HRC60-64 for dimensional stability. Assembly is completed in a cleanroom. The integrated ABS sensor precisely calibrates the signal, while preload is controlled to ensure rotational accuracy.

يخضع المنتج النهائي لموازنة ديناميكية، وختم مقاوم للماء، واختبارات طويلة الأمد، ويلبي معايير IATF16949 ويلبي متطلبات السرعة العالية والحمل الثقيل لمركبات السيارات.
