Hub bearing assembly for a vehicle wheel, the assembly having an axial tubular appendage capable of being inserted into a central hole of a wheel of the vehicle, and wherein the tubular appendage has a radially outer surface of substantially cylindrical shape; a collar of cylindrical shape being mounted on the tubular appendage so as to cover a second centring section of the radially outer cylindrical surface, and having an insert of metallic material and an inner coating layer which at least partially covers the insert and is formed on the insert by galvanizing.

A bearing unit having at least one row of rolling bodies; and at least one cage for retaining a respective one of the at least one row of rolling bodies. The at least one cage comprising at least one base bar, a plurality of arms circumferentially spaced apart and extending from one side of the base bar, and a plurality of partially spherical cavities for retaining the respective one of the at least one row of rolling bodies. The respective row of rolling bodies and the at least one cage are in contact with each other along contact points positioned near a polar region of the respective one of the at least one row of rolling bodies, so that an angular distance (&#x3b1;) of the contact points with respect to an equator of the respective one of the at least one row of rolling bodies is between 40&#xb0; and 75&#xb0;.

Bearing unit with retaining cage

A roller bearing including an outer ring, at least one inner ring and a plurality of rolling bodies inserted between the outer ring and the inner ring. The outer ring presents an osculation of between 0.51 and 0.56 and the inner ring presents an annular race having a bottom surface delimited by an annular relief () including a cylindrical section () with a greater diameter than that of the bottom surface (), a first convex curved section () having a pre-established radius of curvature (R) and which connects with continuity the annular bottom surface () of the first annular race with the cylindrical section (), a second convex curved section () which connects with continuity with the cylindrical section () and a third concave curved section () that connects with continuity with the second section ().

A sensor-carrier cap for a bearing of a wheel hub, the cap being made of plastic material and having a bottom wall arranged transversely to a central axis and providing a seat for accommodating a sensor, a cylindrical mounting wall extending axially from one side of the bottom wall around the axis; snap locking means projecting in a radially outer direction from the cylindrical wall, for locking the sensor-carrier cap on a tubular appendage of a wheel hub-bearing.

A protective screen mounted on an outer cylindrical surface of a constant-velocity joint and facing towards a sealing device of a rolling-contact bearing which is angularly coupled to the constant-velocity joint for protecting the sealing device and the rolling-contact bearing from the action of external agents; the screen being provided with: an annular wall, which is transverse to an axis (A) of rotation of the constant-velocity joint and is arranged in axial abutment against a side wall of said constant-velocity joint, a central hole, which is made through the annular wall and through which a shaft of the constant-velocity joint passes with play, and a plurality of elastic mounting and centering fins, which are distributed uniformly about the central hole and extend unsupported from the annular wall such that they are coupled to the outer cylindrical surface of the constant-velocity joint.
