Multi passage rotary union with integrated slip ring.

 A multi passage rotary Union  is a machine element, making it possible to feed  several mediums (compressed air, water, cooling fluids, vacuum...) from a stationary line into a rotating machine section.


In combined version,  One multi circuits slip ring is integrated on the rotary union (for electrical power, signals...).
