A sliding bearing is provided for a magnetically driven centrifugal pump with an outer stationary tubular bearing housing within which lie antirotationally mounted bearing bushings and with a rotationally mounted hollow bearing shaft, lying coaxially in the bearing housing to accommodate the pump impeller shaft, having bearing sleeves, lying within the bearing bushings. Contacting the end faces of the bearing bushings on the outer side lie axial bearing rings which are in each case held by an outer axial disc arranged on or alongside the bearing shaft at both ends. The sliding bearing constitutes a preassembled unit, the parts of which are captively mounted to one another. The two axial discs at the end faces are fastened to or alongside the bearing shaft and hold the bearing shaft with its bearings within the bearing housing. |
