INAF ZNAF Qite Hub Bearings, Redefining Driving Experience

In the complex structure of a car, the hub bearing, though seemingly small, plays a crucial role in ensuring driving safety and ride comfort. It acts like the "ankle" of the vehicle, silently supporting the weight of the car and precisely guiding the rotation of the wheels, while withstanding various impacts and vibrations from the road. The Qite hub bearings from INAF ZNAF, with their exquisite craftsmanship, superior quality, and innovative technology, stand out as a trusted choice for both car owners and manufacturers, safeguarding your every journey.
I. Superior Materials, Laying a Solid Foundation
Qite hub bearings control quality from the source, selecting high-strength alloy steel as raw materials. This special steel, after rigorous screening, possesses excellent wear resistance, corrosion resistance, and fatigue resistance, maintaining stable performance even in harsh driving conditions. During production, advanced smelting and forging techniques are employed to further optimize the internal structure of the steel, significantly enhancing its strength. This ensures that the bearings remain robust and durable, without deformation, even under the long-term heavy loads of the vehicle, providing reliable support for the stable rotation of the hub.
II. Innovative Design, Achieving Extraordinary Performance
Unique Structural Design: With a double half inner ring structure, as a double-row angular contact ball bearing, the Qite hub bearing features an extremely ingenious design. This structure not only precisely ensures the axial clearance, allowing the wheels to rotate smoothly and flexibly, but also greatly simplifies the assembly process, improving production and maintenance efficiency. Whether it's continuous operation at high speeds or frequent impacts on complex road conditions, it can handle them with ease, ensuring the close coordination between the wheels and the vehicle body, maintaining good vehicle maneuverability.
Advanced Sealing Technology: Sealing performance is crucial to the service life and operational stability of hub bearings. Qite hub bearings are equipped with sealing devices that have undergone strict testing, with a leakage rate strictly controlled within 10% and a temperature rise not exceeding 65°C. They adopt a composite sealing structure, with high-quality nitrile rubber and SPCC skeletons at the core, effectively blocking the intrusion of external moisture, dust, sand, and other impurities into the bearing, while preventing the leakage of internal lubricating grease. This creates a clean and stable working environment for the bearing, significantly enhancing reliability and durability. Even in wet, muddy, or dusty conditions, they can operate stably.
III. Stringent Processes, Ensuring Reliable Quality
Precision Forging Process: Drawing on advanced forging techniques from Europe and America, Qite hub bearings are produced using multi-station high-speed upsetting forging presses. The forging process alone demonstrates extraordinary quality. The precise forging process ensures the dimensional accuracy and internal structural integrity of the bearings, with uniform material density distribution, greatly enhancing the strength and toughness of the bearings. The subsequent deep cryogenic treatment process further optimizes the metal microstructure, improving the comprehensive performance and service life of the bearings.
Fine Mechanical Processing: In the mechanical processing stage, considering the development of automotive hub bearing units into dedicated hub bearings, Qite uses corresponding car knives for fine turning of the surfaces, ensuring high-precision finishing of the outer rings. Facing the challenges of high hardness and high precision requirements of hub bearing materials, it actively adopts hard turning technology, which not only guarantees processing accuracy but also improves production efficiency. Key parameters such as surface roughness and dimensional accuracy of the bearings are strictly controlled within extremely small error ranges, achieving perfect compatibility with the hub and other components, reducing friction and noise during operation.
IV. Wide Compatibility, Meeting Diverse Needs
Whether it's a city-dwelling family car, emphasizing comfort and handling; a long-distance commercial vehicle, emphasizing load-bearing and durability; or a racing car pursuing ultimate performance, with strict requirements for the precision, strength, and heat dissipation performance of hub bearings, INAF ZNAF Qite hub bearings can precisely meet the needs.
