The present invention discloses an arrangement for cooling a roll ( 5 ). The arrangement comprises a housing ( 2 ) to be secured to the roll ( 5 ), a hollow shaft ( 8 ) mounted for rotational movement within the housing ( 2 ) and a cooling medium line to convey cooling medium into the roll ( 5 ) via the interior of the shaft ( 8 ). The cooling medium line comprising an inlet communicating with an elbow portion, a first length ( 27 ) of the elbow portion ( 20 ) extending from the inlet substantially perpendicular to the axis of the shaft and a second length ( 26 ) of the elbow portion extending from the first length in the direction of the axis of the shaft ( 8 ), the axes of the first and second lengths being in substantially the same plane.
