A wheel having a central hub and a central bore for mounting of the wheel on a shaft, comprises two or more individual, separately manufactured and essentially circular discs which are axially clamped together to form the wheel disc of the wheel. One or more of the individual discs comprises a material, different from that of the remaining discs, and the individual discs are divided in a diametrical division plane that intersects the rotary axis of the discs. A hub, preferably situated on one side of the wheel disc, similarly comprises individual discs which are axially clamped together and clamped to the remainder of the wheel disc. In a wheel having a key slot opening towards the shaft bore, the divisional plane of one or more of the individual discs is preferably angularly off-set in relation to the divisional plane of one or more of adjacent discs so that the individual discs may be mounted on a shaft in different angular positions whereas their respective key slots assume one and the same angular positions. The individual discs or disc portions, respectively, are individually cut by means of a computer controlled laser cutting device. The wheel may also be designed to constitute a V-belt pulley.
