ABSTRACT:
A sealing device is adapted to seal a bearing (2) which is adapted to be positioned in an annular space between two cylindrical and concentric surfaces of two machine elements (30, 32) which are rotatable in relation to each other. The sealing device comprises an annular element (16) which is adapted to be connected with one (26) of the substantially cylindrical surfaces, thereby forming a clearance space in relation to a portion (4) of the bearing (2), which is firmly connectable with the other (28) of the substantially cylindrical surfaces.
The annular element (16) and said portion (4) of the bearing (2) include engagement surfaces (22, 24) which are displaceable to and from firm engagement with each other by axial displacement of the annular element and said portion of the bearing in relation to each other. In the engagement position of the engagement surfaces the sealing device and the bearing form a closed unit, in which the sealing device is protected from dirt, dust and the like during storing and transportation of the unit.
