Abstract
The assembly for supporting in terms of rotation and for sealing a first element (2; 5) rotating in a second element (7) comprises an outer raceway structure consisting of two sheet-metal half-raceways (11; 12) having two coupled outer collar portions (13; 14) serving for mounting the outer raceway structure in an orifice in the second element, and a first (13) of the outer half-raceways carrying the lip seal (22) interacting with the first element (2; 5) forming the inner raceway (10) typically has an extension part (21) opposite the collar portion (13), the lip seal (22) advantageously having a peripheral part (23; 23') forming a static seal and interacting in engagement contact with a wall of the orifice in the second element.
