This rolling assembly comprises a support having a double wheel fitted to it and is characterised in that the support (1) has a circular opening (3) into which a circular spindle (5, 6) being provided at one side of each wheel (7, 8) is inserted from each side, said spindles being thereupon fixedly attached to each other. A bearing being preferentially made up by a self-lubricating bushing is arranged on the periphery of the circular opening (3) of the support (1). |
