Qite Bearings: INAF and ZNAF brands, decoding the precise operation of automotive clutch bearings

In the power transmission system of a car, the coordinated operation of every component is crucial to the overall performance of the vehicle, and the clutch bearing is an indispensable key part. The INAF and ZNAF brands under Qite Bearing, with their deep commitment to technology and quality, have demonstrated the working principle of the clutch bearing through their outstanding product performance, ensuring the efficient and stable operation of automobiles.

Dual Brands Standing Side by Side, Building a Foundation of Quality
INAF and ZNAF, as the two core brands of Qite Bearing, have made significant achievements in the automotive parts field and jointly established the company's excellent reputation. INAF, with its years of industry experience and technological accumulation, has firmly established itself in the traditional automotive parts market, always regarding quality as the lifeline of its products. From optimizing production processes to upgrading quality control, INAF ensures that every product meets or exceeds industry standards through strict process control, becoming a trusted partner for many automakers.
ZNAF, on the other hand, is driven by innovation and actively embraces new technologies and concepts in the industry. It continuously breaks through in areas such as bearing material research and structural design, aiming to bring more competitive products to the market. Whether it is exploring new alloy materials to enhance bearing performance or applying advanced manufacturing processes to optimize product structure, ZNAF is at the forefront of the industry, providing users with more efficient and durable bearing solutions. The two brands complement each other, jointly building the strong brand competitiveness of Qite Bearing.

Exploring the Precise Working Principle of Clutch Bearings
Clutch bearings play a crucial role in the car's transmission system, and their working principle is closely related to operations such as starting and shifting gears. When the driver presses the clutch pedal, the release lever pulls the release bearing, causing it to move forward and push the inner end of the diaphragm spring, causing the diaphragm spring to deform. At this point, the outer end of the diaphragm spring pulls the pressure plate backward, and the pressure between the pressure plate and the driven plate disappears, the friction is released, and the power transmission from the engine is interrupted, thus enabling the gear shift operation. When the driver releases the clutch pedal, under the action of the return spring, the release bearing moves backward, the diaphragm spring returns to its original shape, and the pressure plate presses the driven plate again, allowing the engine power to be transmitted to the transmission again, and the vehicle resumes normal driving.
This series of seemingly simple actions actually place extremely high demands on the performance of the clutch bearing. The bearing needs to have excellent wear resistance to cope with frequent separation and engagement operations; at the same time, it must have good lubrication and a low coefficient of friction to reduce energy loss and ensure the efficiency of power transmission; in addition, in complex working conditions such as high temperatures and high speeds, the stability and reliability of the bearing are also crucial.

INAF and ZNAF Brands, Precisely Meeting the Working Requirements of Clutch Bearings
The INAF and ZNAF brands under Qite Bearing have developed a series of high-performance products based on the working characteristics of clutch bearings, precisely meeting market demands. The clutch release bearings of the INAF brand adopt a special sealing structure design, effectively preventing dust, moisture, and other impurities from entering the bearing, thus extending the bearing's service life. Its high-precision manufacturing process ensures that the bearing remains stable even at high speeds, reducing vibration and noise, and providing drivers with a quieter and more comfortable driving experience. In the clutch system of a well-known family car, the INAF clutch release bearing has undergone long-term usage tests. Even in the frequent start-stop urban traffic conditions, it still maintains good performance, earning high recognition from automakers.
The ZNAF brand, on the other hand, is innovative in the application of bearing materials and structural design. By adopting new high-strength alloy materials, the load-bearing capacity and wear resistance of bearings have been significantly enhanced, enabling them to adapt to more demanding working environments. For instance, the lightweight clutch bearings developed by ZNAF not only ensure strength but also reduce weight, lowering the energy consumption of vehicles. Meanwhile, ZNAF employs advanced lubrication technology to optimize the internal lubrication system of bearings, allowing lubricating oil to be distributed more evenly, further reducing frictional resistance and improving power transmission efficiency. In the commercial vehicle sector, heavy-duty trucks equipped with ZNAF clutch bearings demonstrate outstanding stability and reliability during heavy-load driving and frequent gear shifting, effectively reducing maintenance costs and downtime for vehicles.

Adhering to OEM quality, empowering industry development
As an enterprise with OEM quality matching capabilities, Qite bearings strictly follow quality standards from raw material procurement to product delivery. When manufacturing automotive clutch bearings, high-quality steel, lubricating grease, and other raw materials are selected, and advanced forging and heat treatment processes are employed to endow bearings with excellent mechanical properties. During the production process, high-precision processing equipment and testing instruments are utilized to strictly control the dimensional accuracy and surface quality of bearings, ensuring that products meet OEM quality requirements.

With outstanding product quality and a deep understanding of the working principles of clutch bearings, the products of INAF and ZNAF brands are not only popular in the domestic market but also exported overseas, establishing long-term cooperative relationships with many international renowned automotive brands. Whether for traditional fuel vehicles or new energy vehicles, Qite bearings can provide customized clutch bearing solutions based on the specific needs of different models, continuously empowering the development of the automotive industry.

In today's constantly evolving automotive industry, the INAF and ZNAF brands under Qite bearings will continue to build on their in-depth research of the working principles of automotive clutch bearings, backed by outstanding OEM quality, to continuously innovate and break through, providing global users with higher-quality and more reliable bearing products, and assisting the automotive industry in advancing to a higher stage of development.
