1. A mechanical assembly rotating around an axis of rotation (X-X) comprising a rolling bearing, two mounting parts for respectively mounting two rings of the rolling bearing (8), the mounting parts forming a housing receiving the rolling bearing, one of the rings of the rolling bearing rotating around a central axis (Y-Y) of the rolling bearing which intersects the axis of rotation (X-X), and a device for sealing the housing on a radially outer side according to the axis of rotation (X-X), wherein the sealing device comprises: a first sealing element comprising an annular strip and a first lip which is essentially planar or conical and connected to a portion of the annular strip, located on a radially outer portion of the annular strip according to the axis of rotation (X-X); a second sealing element adjacent to the annular strip and to the first lip, pressing the first lip radially outwards according to the axis of rotation (X-X), against a part associated with a second of the rings; and a sealing portion pressing on an end face of a first of the rings, the end face facing radially outwards according to the axis of rotation (X-X).
