The slip ring is known as a rotary electrical interface, commutator, collector, swivel or an electrical rotary joint. It can improve electromechanical capability, simplify system design and eliminate possible damage while rotation. Likewise, a rotary union is a rotating unit which allows the liquid and/or gas flowing from its input valve to an outlet.

   But how the rotating part looks like when it integrates electricity and gas/liquid transmission into one unit? The hybrid rotary joint developed by JINPAT has answered the question. The coupling comes into a through bore shape and integrated configuration which leaves 6 channels for electrical use and 2 for compressed air respectively.
