In-depth Analysis of the Working Principle of INAF and ZNAF Brand Hydraulic Bearings of Qite Bearing

In the field of automotive parts, bearings are the core components that ensure the stable operation of vehicles. As a core product line of the INAF ZNAF brand, Qite bearings have always been driven by technological innovation. With their outstanding performance and unique design, their hydraulic bearings have occupied an important position in the market. Next, we will delve into the working principle of Qite bearings' INAF ZNAF brand hydraulic bearings.
I. Precise Structure, Laying the Foundation for Performance
The hydraulic bearings of the Qite INAF ZNAF brand adopt a precisely designed structure, consisting of an inner ring, outer ring, hydraulic oil cavity, sealing device, and special oil channels. The inner ring fits tightly with the shaft and rotates synchronously with it; the outer ring is fixed on the corresponding component, providing support and positioning. The core hydraulic oil cavity is filled with high-performance hydraulic oil independently developed by Qite, which maintains stable lubrication performance and viscosity characteristics even under high temperature and high pressure.
The sealing device uses Qite's unique multi-layer composite sealing technology, combining high-performance rubber and special coating materials, which can prevent hydraulic oil leakage and effectively block external impurities. The specially designed oil channels are the result of countless fluid mechanics simulations and experiments by Qite engineers, precisely guiding the hydraulic oil to circulate within the bearing, achieving the best lubrication and heat dissipation effects.
II. Dynamic Operation, Unveiling the Working Principle
(1) At the moment of startup, lubrication takes the lead
When the car engine starts, the shaft drives the inner ring of the bearing to rotate, and the stationary hydraulic oil is subjected to shear force. At this time, the Qite hydraulic bearing utilizes the capillary effect and the precisely designed initial pressure difference structure to quickly form an extremely thin lubricating film in the tiny gap between the shaft and the inner ring. This film not only reduces the starting friction but also can withstand a certain impact at the moment of startup, protecting the bearing components from damage.
(2) High-speed operation, stable support
As the shaft speed increases, under the guidance of the special oil channels, the hydraulic oil circulates. Centrifugal force throws the hydraulic oil to the outer ring, forming a pressure oil film in the gap between the shaft and the inner and outer rings. Through the optimized oil film distribution design of Qite bearings, the oil film pressure is uniform, not only reducing friction and energy loss but also using the hydraulic support force to lift the shaft, achieving non-contact operation. At the same time, the damping characteristics of the oil film effectively absorb the vibrations generated by the high-speed rotation of the shaft, combined with Qite's unique shock absorption structure design, making the operation more stable and quiet.
(3) Load changes, intelligent response
During vehicle operation, the load is variable. Qite hydraulic bearings demonstrate strong adaptive capabilities. When the load increases, the gap between the shaft and the bearing decreases, and the oil film is compressed, increasing the pressure. Based on Pascal's law, the hydraulic oil evenly transmits the pressure. Qite's unique pressure sensing and adjustment structure can automatically adjust the oil film thickness and pressure distribution in real time according to the load. When the load decreases, it also adjusts quickly, ensuring stable operation of the bearing under various working conditions.
III. Technological Advantages, Highlighting Brand Strength
(1) Long service life, reducing costs
The non-contact operation mode of Qite bearings' INAF ZNAF brand hydraulic bearings significantly reduces solid friction. Combined with Qite's strict raw material selection standards and advanced manufacturing processes, the wear degree is much lower than that of traditional bearings under long-term and high-load operation, significantly extending the service life and reducing the frequency of vehicle maintenance and replacement, saving costs for users.
(2) Precise and stable, enhancing performance
The powerful oil film damping and support capabilities, combined with Qite's high-precision manufacturing technology, effectively suppress the vibration and deviation of the shaft. In applications such as engine crankshafts and transmission shafts, which have high precision requirements, it ensures precise operation trajectories, enhancing the performance of the vehicle's power system and making power transmission more efficient and stable.
(3) Silent operation, comfort upgrade
Qite bearings' INAF ZNAF brand hydraulic bearings operate silently, providing a more comfortable driving experience. The damping effect of the oil film effectively reduces noise and vibration, making the vehicle's operation smoother and quieter. This not only improves the comfort of the ride but also contributes to a more pleasant driving environment. The shock absorption and vibration damping of the hydraulic oil film, combined with Qite's acoustic optimization design of the bearing structure, significantly reduces operating noise. Compared with traditional ball bearings, Qite's hydraulic bearings operate with much lower noise, creating a quiet and comfortable in-car environment for drivers and passengers.

IV. Widespread Application, Empowering Core Automotive Systems
(1) A Reliable Partner for Engine Systems
Inside the engine, the rotational accuracy and stability of key components such as the crankshaft and camshaft are of critical importance. Qite's hydraulic bearings, with their outstanding performance, effectively enhance the engine's power output efficiency, reduce energy consumption, minimize faults, and extend the engine's overall lifespan, providing a solid guarantee for the engine's efficient and reliable operation.
(2) A Performance Booster for Transmission Systems
In the transmission, the input shaft, output shaft, and gear-shifting gear shaft system bear complex and variable loads. Qite's hydraulic bearings can precisely adjust the oil film, ensuring smooth operation of the shaft system, reducing shift shock, improving shift smoothness and reliability, optimizing transmission performance, and enhancing the driving experience.
