Herein a centrifugal separator is disclosed. The centrifugal separator comprises a housing, a spindle (6), and a rotor. The spindle is only journalled in a bearing arrangement fixedly positioned in the housing at the first axial end portion. The centrifugal separator comprises a seal (24) arranged between the spindle (6) and the housing. The seal (24) is arranged at a distance from the bearing arrangement where the spindle (6) is subjected to deflection. The seal (24) comprises a cylindrical inner surface (26) associated with the housing, a circular slot (28) in the spindle (6) or in a rotating member (30) associated with the spindle (6), and a piston ring (32) arranged in the slot (28) and abutting against the cylindrical inner surface (26). |
