The roller table roll comprises a roll shaft (4) and a roll casing (1) that is mounted on the roll shaft (4) at least at the roll ends (2; 3). The aim of the invention is to prevent damages caused by electric currents and by sparking on the product surface. To this end, the roll casing (1) is mounted on the roll shaft (4) while being electrically and/or thermally insulated at least at the roll ends (2; 3).
