Before the direction of the regularity of the construction set (12) for a roller stand (2), of a brake body (16) as well as a carrier (18), on which the brake body (16) is attachable. Further comprises before the direction of the regularity of the construction set (12) of a support (38) with a support surface (40), at which the carrier (18) and which can be supported in the form of at least a portion has an outer cylindrical surface. The supporting body (38) also comprises a receiving element (42), which is adapted to, a wheel (6) of the directly (2) or at least a partial section of a wheel axle (8) of the directly (2) to receive in such a way that, in the event of the receiving of the wheel (6) according to the accommodation of an axis of symmetry (74) of the wheel (6) parallel to and offset with respect to a cylinder axis (46) of the support surface (40) extends and in the case of the receiving the wheel axle (8) according to the receiving an axis of symmetry (74) of the wheel axle (8) parallel to and offset with respect to said cylinder axis (46) extends.
