Abstract: A water-cooled roll is used for transporting material in a heated environment. The roll includes a hollow rotatable arbor with a system for supplying cooling water to the interior of the arbor. A plurality of annular tires are spaced along the arbor, each tire including a plurality of recesses spaced along an inner periphery of the tire on opposite sides of the tire. A plurality of locking bars are attached to the arbor, each locking bar extending into one recess of one tire. Each tire includes at least two locking bars extending into recesses thereof for rotationally and axially positioning the tire on the arbor.
