Abstract The invention relates to a submersible pump comprising a bearing arrangement (1) having a bearing cover (32) and a bearing flange (31) and having one or more bearing elements (2) each having an inner bearing ring (21), an outer bearing ring (23) and a roller element (22), and comprising a rotor shaft (4) which is rotatably supported in the bearing element (2) about an axis of rotation (A) extending in a longitudinal axial direction such that the inner bearing ring (21) rotates along with the rotor shaft (4) in the operating state. The bearing element (2) is arranged at the bearing flange (31) such that the bearing cover (32) tensions each outer bearing ring (23) in a longitudinal axial direction and such that a peripheral gap (5) having a predefinable axial width is formed in a radial direction between the outer bearing ring (23) and the bearing cover (32) and between the outer bearing ring (23) and the bearing flange (31). The invention furthermore relates to a bearing arrangement for a submersible pump. Fig. 1 - -- -- ---- -- -- -- -- -- -- -- -- -- - - -- |
