Pneumatic valve is a kind of valve controlled by air pressure, which is widely used in industrial automation control system. Its main applications include the following aspects:
1. Fluid control: pneumatic valve can be used to control the flow and direction of liquid or gas, such as controlling the flow in the pipeline, exhaust gas emission, etc.
2. Pressure control: pneumatic valve can be used to control the pressure of fluid, such as controlling the pressure of compressed air, regulating the pressure in the hydraulic system, etc.
3. Temperature control: pneumatic valve can be used to control the temperature of fluid, such as the temperature of heating or cooling system.
4. Automatic control: pneumatic valve can be linked with sensors, PLC and other equipment to realize automatic control, such as automatic production lines, robots, etc.
5. Safety control: pneumatic valve can be used for safety control, such as controlling emergency stop, preventing overload, etc.
In general, pneumatic valve plays an important role in industrial automation control system, which can improve production efficiency, reduce costs, and ensure safety.

FAG bearings are widely used in the machinery industry and are considered essential components, often referred to as mechanical joints. Their simple structure and complex external design require advanced materials, precise manufacturing processes, and optimal operating conditions. The development of bearings involves comprehensive planning and analysis, especially for large-scale applications. Traditionally, most bearing professionals have relied on 2D CAD drawings and Excel-based designs, with some using simplified 3D modeling systems. However, this approach has led to limited innovation, lower production efficiency, and reduced product reliability and lifespan. As a result, many domestic companies struggle to meet future demands and achieve economies of scale.
The processing of export bearing rings varies depending on the raw material or blank form. The inner and outer rings undergo different treatments before machining. The general process includes: bar or pipe material (some may require casting and annealing, normalization) → turning → heat treatment → grinding → finishing or polishing → final inspection → rust prevention → packaging → (to be opened). This systematic approach ensures quality and performance.
When it comes to replacing bearings, two common methods are often used. One is direct heating using acetylene and oxygen, while the other involves oil immersion heating for smaller bearings. These techniques allow for thermal expansion, which helps in increasing the inner diameter of the bearing, making removal easier. These methods are commonly applied in temporary equipment maintenance and effectively address bearing disassembly challenges during repairs.
With the continuous improvement of equipment and technical standards, domestic companies such as Wazhou and Tianma are gradually expanding their market presence. They are moving beyond traditional FAG yaw and pitch bearings into more advanced areas like spindle bearings and gear box bearings, showing promising growth in the global market.
