Claim Text:
1. A cover for a wheel-hub bearing, the cover being made of plastic and comprising: an end wall arranged transversely with respect to a central axis (X), a cylindrical mounting wall which extends axially from one side of the end wall around the central axis (X), an outer surface of the cylindrical mounting wall having a first protrusion, a second protrusion, and an axially extending surface between the first and second protrusions, wherein the first and second protrusions extend radially outwardly with respect to the axially extending surface; the cover being configured to lock to a tubular appendage of the bearing, wherein an inner surface of the tubular appendage comprises an intermediate surface that is axially between an axial outer portion and an axially inner portion, the axial outer portion and the axial inner portion each having internal diameters that are greater than an intermediate surface diameter, the axial outer portion being connected to the intermediate surface by a first connecting surface, the axial inner portion being connected to the intermediate surface by a second connecting surface, a first diameter of the axially extending surface of the cylindrical mounting wall is less than or equal to the intermediate surface diameter such that no axially extending surface of the cylindrical mounting wall is configured to be in an interference fit or a press fit with the tubular appendage, the first projection of the cylindrical mounting wall having an outer diameter that is greater than the intermediate surface diameter and is configured to engage with the first connecting surface to lock the cover to the tubular appendage; the cover including a ring arranged between the second protrusion of the cover and the tubular appendage, wherein the ring is configured to exert a resilient recall action on the first projection.
