Abstract

[Bearing device with integrated electrical insulation, in particular for an electric motor or machine] This bearing device comprises a bearing 10 provided with a first ring 12 and a second ring 14 capable of rotating relative to each other. The device comprises at least one insulating sleeve 22 mounted on the second ring 14 of the bearing and provided with a bushing 24 and an insulating lining 26 overmolded on the second ring 14 and made of electrically insulating material. The bushing comprises a first axial flange 24a and a second axial flange 24b connected by a central radial core 24c. The insulating lining 26 covers at least the second axial flange 24b, the first axial flange 24a being radially offset relative to the insulating lining 26 on the side opposite the bearing 10.
