摘要

This invention relates to a rotating and sealed bearing assembly of a first member (12) rotating in a second member (10), comprising a bearing outer track structure (28) mounted in a bore (11) of the second member traversed by the first member (12) and bearing a lip seal (40), the bearing inner track (24) being formed on the first member (12), the bearing outer track structure being made of a sheet steel backing plate (28) shaped in order to a present an intermediate zone of rounded profile (26) forming the bearing outer track. According to the invention, the intermediate zone (26) is extended on one side by a first end zone (30) extending axially and on the other side by a second end zone (36) extending axially, the second end zone (36) being connected to the intermediate zone (26) by a mediane zone (34) extending radially.
