The invention relates to a demountable hub connection having a shaft (6) or an axis that is configured on the basis of a friction fit connection. In view of weight reduction and cost-effective construction, two clamping parts (3, 4) are proposed, which as intermediate bearings elements have at least two half shells (8, 9) having a hard particle layer such that during the tensioning of the clamping parts, a kind of micro toothing between the hard particle layer and the smooth surfaces of the clamping parts on the one hand, and the shaft surface on the other hand is achieved.
