Hydraulic Rotary Union Pneumatic for Air, Vacuum, and Fluids

Description

Product overview

A Pneumatic Rotary Union, also known as a rotary joint, is a specialized fitting that allows for the rotation between stationary and moving parts in a pneumatic system. It acts as a bridge, enabling the easy flow of compressed air or gases from a stationary source to a rotating component, such as a drum, spindle, or cylinder. By facilitating this transfer, the Pneumatic Rotary Union ensures that the pneumatic system can function effectively, even in applications where continuous rotation is required.

In industrial pneumatic systems, rotary union pneumatic components serve as critical compressed air transmission hubs between stationary pipes and rotating machinery. Our precision-engineered pneumatic rotary union guarantees zero-leak air sealing performance, supporting pressures up to 150 PSI and speeds of 500 RPM. Designed with dual ball bearing stabilization and corrosion-resistant stainless steel housing, it excels in automated assembly lines, CNC tool changers, and robotic arm applications.

How to Choose the Right Pneumatic Rotary Union for Your Application​

When selecting a Pneumatic Rotary Union for your application, it is important to consider several factors to ensure optimal performance and compatibility. Here are some key factors to keep in mind:​

1. Operating Pressure​

Determine the maximum operating pressure of your pneumatic system and choose a Pneumatic Rotary Union that is rated to handle that pressure. It is crucial to select a union with a pressure rating that exceeds the maximum pressure your system will encounter to ensure safe and reliable operation.​

2. Rotational Speed​

Consider the rotational speed of the component so that the union will be connected. Some Pneumatic Rotary Unions are designed for high-speed applications, while others are more suitable for low-speed operations. Make sure to choose a union that can handle the rotational speed requirements of your application.​

3. Media Type​

Identify the type of media that will be flowing through the union, such as compressed air, gases, or fluids. Different Pneumatic Rotary Unions handle specific media types, making it essential to choose a union compatible with your intended media.​

4. Number of Passages​

Determine the number of passages required for your application. If you need to transfer multiple media or have a complex pneumatic system, you may require a multi-channel Pneumatic Rotary Union. Consider the future expansion of your system as well and choose a union that can accommodate any potential changes.​

5. Port Size and Thread Type​

Ensure that the port size and thread type of the Pneumatic Rotary Union match the connections in your pneumatic system. This will ensure a proper fit and a secure connection, preventing any leakage or performance issues.​

6. Customization Options​

If your application has unique requirements, look for a manufacturer that offers customization options for their Pneumatic Rotary Unions. This will allow you to get a union that is tailored to your specific needs, ensuring optimal performance and compatibility.​
