A bearing device includes a bearing, a bushing and an electrically insulating insert interposed between and connecting the bushing and a ring of the bearing. The bushing has a cylindrical surface and first and second axially facing front faces at either axial end of the cylindrical surface, and a connection chamfer connects the first front face to the cylindrical surface of the bushing. The connection chamfer has a radiused portion meeting the first front face at a first sharp edge and a spherical surface extending from the radiused portion to the cylindrical surface of the bushing and meeting the cylindrical surface of the bushing at a second sharp edge. A value of a radius of the spherical surface increases in a direction toward the second front face.
