A bearing device includes a first ring and a second ring configured to rotate relative to one another and an insulating sleeve formed from a bushing and an electrically insulating lining. The lining is overmolded on the bushing and on the second ring and connects the bushing to the second ring. The radial internal or external surface of the bushing incudes at least one helicoidal groove and the lining incudes at least one fastening rib having a shape complementary to a shape of the at least one helicoidal groove that extends into the at least one helicoidal groove. The helicoidal groove extends circumferentially at least 360 degrees around the radial internal or external surface of the bushing or the radial internal surface of the bushing.
