ABSTRACT The invention relates to a roller for furnaces, particularly for iron and steel making furnaces for heating slabs, or the like, this roller being part of a sole consisting of a plurality of rollers substantially parallel to each other, and being provided with a plurality of annular collars (6, 6', 10) (annular riders) which are side by side and spaced apart, the rollers (1) and the annular collars (6, 6', 10) being cooled with a cooling fluid. According to the invention, the annular collars (annular riders) (6, 6', 10) are cooled by means of a flow of cooling fluid which is orientated transversely with respect to their axis and parallel to their median plane. The annular riders are made in tubular form and may be of toroidal form (6, 6') and are connected separately each to the supply duct (3) and to the return duct (2) for the cooling fluid. They may also be formed by the individual turns of a tubular spiral (10) or by a number of successive segments of a spiral which are connected via their ends to the supply duct (3) and to the return duct (2).
