An end piece suitable for forming a spacer for a roll having two concentric tubes with axis, including spokes connecting two inner and outer cylindrical portions, and is where a fluid circuit originating from the center towards the periphery includes a first circumferential groove arranged in the inner cylindrical portion and a second circumferential groove arranged in the outer cylindrical portion connected by at least one pipe, such that the end piece makes it possible to reduce the weight of the roll by approximately 20%, to facilitate the balancing of the roll while ensuring accessibility to the inside of the roll between the two tubes and to enable easy mounting without indexing due to the circumferential grooves, and where the end piece with spokes enables access to the inside of the roll when it is mounted and thus enables both more accurate balancing than with solid end pieces that require the piercing of the outer tube and the invisibility of this balancing from the outside of the roll.
