A wheel bearing device with a built-in homokinetic coupling, including a generally annular inner part, an outer race and two rows of rolling elements located between the outside running surfaces formed on the outer race and the inside running surfaces applied to the inner part. The outer race is equipped with a radially extending flange for the attachment of the bearing, and the annular inner part is equipped with a radially extending flange to which the hub of a wheel can be attached. This inner part forms at the same time one unit with the outer ring of the homokinetic coupling characterized by the fact that the flange of the inner part is extended with a brake element which forms the part to be braked of a braking mechanism. The inner part of the bearing, the carrier flange for the wheel, the brake element and the outer ring of the homokinetic coupling forms one homogeneous unit. The inner raceway surfaces for the rolling elements are formed of a high grade bearing material. The inner part has an axial stub directed away from the homokinetic coupling and extending beyond the attachment flange to define a guide means for the hub of the wheel.
