The invention relates to a coupling for an oil/air mixture used in oil/air lubrication, and a method for the use thereof, wherein the oil/air coupling also comprises electric contacts (3, 13) such that in addition to the transmission of the oil/air mixture, the coupling may also conduct electric current via electric connections (3, 13). Such an arrangement facilitates, among other things, an automated coupling or decoupling during a roller change in a rolling mill.
