A backing ring assembly is for railway axles and includes a backing ring and an annular insert having L-shaped axial cross sections. The insert includes a sleeve portion fitted to a radially outer cylindrical surface of the backing ring, which delimits a first axial section thereof. The annular insert sleeve portion includes first and second axial sections hingedly connected by an intermediate, reduced thickness section designed to form a plastic hinge. The first axial section of the sleeve portion projects axially from the first section of the backing ring, which is provided with an annular projection designed to induce elastic deformation of the reduced thickness section to ensure that the second axial section of the sleeve portion is always coupled with the cylindrical outer surface of the backing ring first axial section by an interference fit.
