    摘要： The invention relates to an electrical machine (1), particularly an electric motor, comprising a housing (2) and lids (3, 4) which occlude said housing (2) and inside which bearings (7, 8) are disposed for rotatably mounting a rotor (5). The inventive electrical machine further comprises spring elements (7.3, 8.3) which impinge at least one respective shell (7.1, 7.2, 8.1, 8.2) of the bearings (7, 8) with a pressure that acts in an axial direction. The fastening member of the bearing shell (7.1, 7.2, 8.1, 8.2) that is impinged upon by one respective spring element (7.3, 8.3) is embodied as a sliding seat.
