Adjacent peripheral bores (3) along the roller are joined as a group by connecting channels (4), to pass the thermal fluid. At one end there are drain channels (5), which connect grouped peripheral bores. Preferred features: At least three adjacent peripheral bores are joined together by connecting channels. The drain channels are formed in the roller body (1) or in the stub shaft flange (2). Seals are arranged between each connecting channel and the associated peripheral bore, between the flange and the roller body. Drain channels join connecting channels from adjacent groups. The drain channels are milled or turned peripherally and extend continuously, between the bores. Their cross sections are smaller than those of the connection channels between peripheral bores. An drain opening (6) is joined to a connecting channel and/or to a peripheral bore. It is located in the stub shaft and extends radially to its exterior.
