Working principle of rotary joints

The working principle of a rotary joint, thank you
The joint is rotatable, so it generally has a spherical hinge structure
Is it a metal bellows? For those with spherical sealing surfaces, well, once such surfaces get worn out in our company, they become almost unusable; in that case, the entire metal bellows has to be replaced. Later on, we switched to flat sealing surfaces and used gaskets – whenever one of these gaskets gets damaged, only it needs to be replaced, without having to replace the whole bellows. However, the spherical sealing surface should be used in medium-pressure systems.
