Abstract
A bearing device includes a bearing having a first ring and a second ring mounted for relative rotation, and an insulating sleeve mounted on the second ring. The insulating sleeve includes a socket and an electrically insulating liner that contacts the second ring. The second ring has a radial outer surface and a radial inner surface delimiting a radial thickness of the second ring, and the insulating liner is overmolded on the socket and at least on one of the inner and outer surfaces of the second ring of the bearing. Also, the surface of the second ring is configured to retain, in the circumferential direction, the insulating liner relative to the surface by complementarity of shapes with the insulating liner.
