ABSTRACT:
A roller, particularly for a roller hearth furnace for heating materials to high temperatures, has a supporting body defining a roller axis and having a curved center line and a cross-section substantially normal to said center line. The supporting body includes a plurality of portions which are connected with one another and radially surround the roller axis in spaced relationship therewith. The portions extend in a circumferential direction and are positioned at axially spaced locations relative to one another so that a periphery of the roller is materially formed only at locations corresponding to the axially spaced locations of the portions and the roller has a plurality of empty regions between these locations.
