A device is disclosed for coupling a coolant supply and/or coolant drainage to a roll, especially in a continuous casting installation, wherein the roll includes a journal, which is mounted rotatably in a bearing block, and a lateral recess, extending in the axial direction, and at least one roll cooling channel, through which a coolant can pass. The device includes at least one coolant channel, which can be brought into fluidic connection with the roll cooling channel on the journal side; and a sealing unit for sealing the fluidic connection between the coolant channel and the roll cooling channel, including an inner module and an outer module. The inner module includes a hollow cylindrical element, which can be inserted into the lateral recess of the journal, and which, when viewed in the axial direction, has no flange on the outer side of the journal.
