Rotary unions, also known as rotary joints or rotating unions, are devices that allow the transfer of fluid or gas from a stationary source to a rotating machine part.

rotary union, also known as a rotary joint or swivel joint, is a mechanical device that allows the transfer of fluid or gas from a stationary pipe to a rotating parts , such as a shaft or drum.

A rotary union, also known as a rotary joint or rotating union, is a mechanical device that allows fluid or gas to flow through a rotating component, such as a shaft or spindle, without leaking or interrupting the flow.

Rotary Union provides a seal between a stationary supply passage to rotating part, in this way, rotary union can transfer fluid from a stationary side to rotating part.Rotary unions can be designed with multiple flow passages to transfer different media simultaneously, such as: Hydraulic oil, Cool
