    摘要： A sealing device intended for sealing between an axle journal (21, 22, 23, 24) and a bearing housing (30, 57, 31, 58) for the axle journal (21, 22, 23, 24). The sealing device allows that the axle journal (21, 22, 23, 24) can be angled in a plane in relation to the bearing housing and can also take up axial movement. The sealing device comprises a stator ring (40), which is carried by two guide pins (41), and the stator ring (40) can be angled in a plane in relation to the guide pins (41). The sealing device comprises also a sealing ring unit (47), which is intended for sealing between the stator ring (40) and axle journal (21, 22, 23, 24), a bellow means (56), which is intended for sealing between the bearing housing (30, 57, 31, 58) and stator ring (40), and at least one resilient element (48), which is intended to ensure that the stator ring (40) abuts the sealing ring unit (47). The bellows means (56) can be made of a material withstanding aggressive liquids.
