Sealing between two rotatable elements, for example a shaft and a hub

摘要

A sealing device of the type cassette seal for sealing a space between for example a shaft (40) and a hub (42) comprises a housing (4) having a sleeve-shaped section (30) connectable with the hub (42) and an annular section (32) angled from the sleeve-shaped section (30) and directed towards the shaft (40). The sealing device further comprises a cap (6) having a sleeve-shaped section (8) which is connectable with the shaft (40) and a section (10) which is angled from the sleeve-shaped section and is directed towards the hub (42). The annular section (10) of the cap (6) supports a sealing lip (14) engaging the sleeve-shaped section (30) of the housing (4). The cap (6) has at its sleeve-shaped section (8) an edge portion (12) which is foldable in the direction against the hub (42) over the edge portion of the angled annular section (32) of the housing (4) for locking together the housing and the cap in the axial direction. The foldable edge portion (12) of the cap supports a sealing lip (24) which subsequently to the folding of the fold edge portion (12) slidably engages the annular section (32) of the housing (4). <IMAGE>
