Zusammenfassung:	The invention relates to a roller of the type that comprises, on one hand, a drive shaft, which has a cylindrical envelope surface having a certain outer diameter and a certain length, and, on the other hand, a shorter roller ring, which includes an outer ring of a hard material and an inner ring concentric with the same and of a more ductile material, which includes a cylindrical inside having a certain inner diameter and is, on one hand, permanently united to the outer ring in a metallurgical way, and, on the other hand, rotationally rigidly connected with the drive shaft in order to, from the same, transfer torque to the outer ring. According to the invention, the rotationally rigid joint between the drive shaft and the roller ring solely consists of a shrink-fit joint that is established between the envelope surface of the drive shaft and the inside of the inner ring and has an interference of at least 0.01% of the outer diameter of the drive shaft.
