Rotary Union for Steam

A steam rotary union, also known as a rotary joint, is a mechanical device that allows for the transfer of steam from a stationary source to a rotating component. It features seals and bearings that enable smooth rotation while preventing leaks, making it essential in various industrial applications such as power generation and manufacturing.
