TISTAM® provide different types of a rotary joint depend on mechanism used to transfer liquids and/or gases while rotating / swiveling from one connection to another. Rotary unions are engineered to endure a large range of temperature and pressure for a variety of conditions and environments. In addition, rotary unions may integrate multi plepassages and handle different types of media concurrently.
Rotary unions function by connecting to an input and securing onto another mechanism while allowing a moving connection to be preserved. They are utilized in a variety of applications; from miniature rotary unions for the semiconductor industry to large, heavy-duty rotary unions for industrial applications. Additionally, numerous materials, seals, and bearing types can be incorporated.
