A bearing includes an inner ring, an outer ring and a sealing device. The sealing device includes at least an outer structure secured to the outer ring, and an inner structure secured to the inner ring. The inner structure includes a shrink-fitting portion shrink-fitted onto a shrink-fitting bearing surface of the inner ring and at least one seal seat. The outer structure includes at least one seal lip in sliding contact against the seal seat. The seal seat is located axially at a distance from an end wall of the inner ring, and is closer to the axis of revolution than the shrink-fitting portion.
