In modern industrial production, the stable operation of equipment often depends on efficient connection technology. As a key sealing connection device, rotary joints are able to realize reliable connection between equipment and pipelines under different working conditions, and at the same time ensure stable transmission of fluid or power. Whether in the semiconductor industry, industrial automation, precision machining, chemical industry, oil and gas extraction, steel manufacturing, or automotive, aerospace and other high-end fields, rotary joints play an irreplaceable role. Its excellent sealing, high temperature and pressure resistance, and the ability to adapt to complex working conditions make it an indispensable core component in many industries.

7 important application areas for rotary joints:

1. Industrial Automation and Precision Machining

In the field of industrial automation and precision machining, rotary joints, as the “power link” connecting rotating parts and fixed pipelines, have a direct impact on the stability and efficiency of equipment operation. With its three core advantages of high speed, high pressure resistance and strong sealing, rotary joints have become the preferred solution for machine tool spindle cooling and pure water transportation. Rotary joints are also widely used in all kinds of machining centers, drilling/reaming machines and other special equipment for conveying water, gas, hydraulic pressure, steam, hot oil, vacuum and coolant and other media.

2. Semiconductor Industry

Key applications for rotary joints in the semiconductor industry include chemical mechanical polishing (CMP) equipment, wafer cleaning processes and core processes such as electrochemical deposition (ECD) and atomic layer deposition (ALD). In CMP equipment, RIX MF series rotary joints provide leak-free supply of abrasive fluids and efficient discharge of waste fluids through non-metallic main circuits and gap sealing technology. In the wafer cleaning process, RIX MFC series multi-channel rotary joints are used to quickly switch between pure water, chemical solutions (e.g. SC-1, SC-2 cleaning solution) and drying gases to ensure precise control of the cleaning process. For precision deposition processes such as ECD and ALD, the RIX L40 rotary joints minimize the effect of thermal deformation on sealing performance thanks to low coefficient of thermal expansion materials, thus maintaining process temperature stability and reliably transferring coolant or reaction gases.

3. Chemical Industry

In chemical production, rotary joints are mainly used to convey, separate and mix different fluids or granular materials. In equipment such as centrifuges, for example, the internal structure of rotary joints ensures even distribution of fluids, increasing productivity while maintaining stable operation and reducing the risk of leakage.

4. Oil and Gas Extraction Industry

Oil and gas extraction environments are usually characterized by high pressure, high temperature and strong corrosion, which puts extreme demands on the reliability of connection components. Rotary joints are widely used in oil well drilling, hydraulic control systems and other scenarios to ensure stable delivery of liquid media. In order to adapt to the harsh working conditions, metal hard-to-hard friction sub-materials can be used to improve wear resistance and service life. In addition, rotary joints can effectively reduce noise, minimize commutation problems, and have self-lubricating function, so that the equipment will not be damaged due to flinging out contaminants even at high speeds.

5. Steel Industry

Steel production environment is harsh, continuous casting, forging and other processes require high durability and adaptability of equipment. Rotary joints are widely used in intermediate ladles, ladle cars, hopper cars and piping systems as the key interface for power transmission. Whether it is high-viscosity slurry, crystalline materials, or strong scouring media, rotary joints can operate stably. If necessary, high strength wear-resistant protective sleeve can be added to further extend the service life.

6. Automotive Industry

In automotive manufacturing, the connection between the engine and the transmission requires an efficient and reliable means of power transmission. Rotary joints not only ensure the stability of the connection, but also enhance the overall performance and safety of the vehicle, making them an important component in modern automobile manufacturing.

7. Aerospace Engineering

The aerospace field requires high reliability and stability of equipment, and traditional connection methods are difficult to meet the demand. Rotary joints are made of high-strength metal materials and precision processing technology, with high corrosion resistance and impact resistance, able to adapt to extreme environments and ensure the safe operation of aircraft.

As a key technology in the industrial field, rotary joints have become an indispensable core component in many industries by virtue of their excellent sealing performance, high-pressure and high-temperature resistance, and wide applicability. With the continuous development of industrial technology, the application scope of rotary joints will be further expanded and their performance will be continuously optimized to provide stronger support for the efficient and safe operation of modern industry. In the future, with the application of new materials and new technology, rotary joints will definitely show their important value in more high-end fields.
