Rotary Unions# Definition
Rotary Union&＃39; is Duff-Norton&＃39;s registered trade name for a type of product known as a rotating joint, rotary joint, swivel joint or rotating union. A rotating joint is a precision mechanical device that allows for the transfer of medium from a stationary fluid supply to a revolving drum or roll.
It is often necessary to heat or cool drums or rolls in process industries like textile, rubber, plastic, paper, and many others. In the paper industry, for example, dryer cans must be kept at a certain temperature in order to dry the wet paper moving over the rolls. Steam is injected into the rolls to heat them up to make the paper dry. However, the dryer cans must keep turning, and the steam supply hose is stationary. A rotating joint is used to transfer the steam （the medium in this case） from the stationary hose that is supplying the steam to the dryer can, which is continually revolving
