How Do Rotary Unions Work?

A rotary union functions by connecting a stationary input (supply) to a rotating part, allowing a moving connection to be preserved and permitting the flow of media (liquids, solids and gases).

You can really tell somebody had a lotta fun making this vid, adding extra stuff just for fun. Good work!

Finally I got the idea how fluids are transferred to track motors. And the thing is called Rotary Union. Great video.

I can barely understand this ''magic". But this is fascinating.
The amount of effort that needs to be put into creating something like this is truly amazing.

Amazing video. Like the applications part, because it concluded it perfectly. Thank you for making this great educational video!

Very nice job ! Great to learn a little bit more ... Always learning !

Impressive Video! I am not easily impressed but this is outstanding! Great job!

It was very clear how it is able to turn continuously... but it was not apparent at all why it turns in the first place. I assume these also include a kind of drive mechanism to make things like excavators swivel in place?

Great video animation, love engineering!

[urbanberndtsson]

So if I understand correctly, there's a... chamber? of sorts that goes full circle so that no matter how much it rotates, the fluid/gas will always be able to reach the exit?

I am also developing this rotary union for one of the automobile part testing, facing some problem integrating the system.

Do you have video for mc series duff norton disassemble

Fantastic animation agree with all comments below

Can we use this rotating hydraulic cylinder to rotate solar panel?

[satishvashistha]

Much usefull application for the industrial.

[oguzhancetin_mech]

I had made one of this but for air. I used it for a gas entrainment impeller

[dabastl]

does an excavator need a 4 way system for it's tracks? to move the left and right side independent for steering?

[ancientpersianempire]

studying for the fl ac exam brought me here looking to see what a rotary pressure joint is lol ummm okay
