= Rotary union
{wiki=Rotary_union}
A rotary union, also known as a rotary joint or swivel joint, is a mechanical device that allows the transmission of fluid (liquid or gas) from a stationary source to a rotating component. This technology is commonly used in applications where pipes or hoses must remain connected while one end rotates, such as in machinery, robotics, and industrial systems. The functioning of a rotary union involves seals and bearings that enable fluid flow through the stationary and rotating parts while minimizing leakage and wear.
