The solution comprises an outer bearing housing (41), which is supported on the lift bogie's body structure, a cylindrical inner bearing housing (42), which is fitted in the outer bearing housing's (41) axial first bore (41a), and a bearing element (43), through which the travelling wheel's shaft is supported in the inner bearing housing (42). The inner periphery (42a) of the inner bearing housing (42) is eccentric in relation to the outer periphery (42b) of the inner bearing housing (42), and the inner bearing housing (42) is locked in the outer bearing housing (41) with a friction lock (45, 46, 47, 49) in such a way that, on the one hand, the inner bearing housing (42) can be rotated step-lessly in the peripheral direction in order to control the desired eccentric position in relation to the outer bearing housing (41) and, one the other hand, it can be moved step-lessly in the axial direction in relation to the outer bearing housing (41) in order to control the desired gauge. |
