FAQ

What is a 4-passage rotary union?

It is a mechanical device that allows the transfer of multiple fluids (such as air, water, oil, or hydraulic fluid) through four independent passages while rotating. This design is essential for applications requiring simultaneous fluid delivery without cross-contamination.

What applications are suitable for 4-passage rotary unions?

Our rotary unions commonly serve a wide range of applications, including CNC machining, robotics, hydraulic systems, and industrial processes that require transferring multiple fluids simultaneously. They are ideal for clamping and unclamping operations, spindle cooling, and powering pneumatic tools.

What are the key features of these kinds of unions?

Multiple Independent Passages: Allows for different fluids to be transferred without mixing.
High Pressure and Speed Ratings: Many models can handle pressures up to 7,500 PSI and rotational speeds exceeding 10,000 RPM.
Robust Sealing Technology: Designed to prevent leakage and prolong service life.

What maintenance is required for 4-passage rotary unions?

Regular maintenance includes inspecting seals for wear, checking for leaks, and ensuring that the operating conditions (pressure and temperature) remain within specified limits. Lubrication may also be necessary depending on the design.

What is the pressure rating for these typical unions?

Pressure ratings can vary widely based on the model and manufacturer. Many standard models can handle pressures from 40 bar (580 PSI) up to 515 bar (7,500 PSI), making them suitable for high-pressure applications.

What materials are commonly used in the construction of the unions?

Carbon Steel: Often used for general-purpose applications.
