In a goods wagon axle bearing assembly of the type provided with a sealing device (20) at its axially outer end, the sealing device comprises a rigid, non-rotating shield (21). Integrated with the sealing device (20) is a current generator, consisting of a magnetised impulse generating ring (25) rotatably fast with one of the rotating parts (12) of the bearing, and a coil (24) operatively facing the magnetised impulse ring and secured to the non-rotating shield (21). The current induced in the coil (24) is supplied to a current drain point on the same goods wagon.

Goods wagon axle bearing assembly

A composite annular element, in particular a magnetic ring usable as a pulse wheel in a rolling bearing of a vehicle wheel hub; the element includes an appropriately polarized plastoferrite ring co-molded onto a metal annular ring for fitment to a rotary member; the metal annular ring is formed in one piece by pressing and bending sheet metal, and presents a sleeve portion for fitment to the rotary member, and a flange portion defining a shoulder for withstanding the axial thrust exerted by an assembly fixture, and connected continuously to the sleeve portion by a rib projecting radially outwards of the sleeve portion; the rib being defined by a 180.degree. bend partially embedded inside the plastoferrite ring so as to leave a continuous annular radial clearance between the plastoferrite ring and the sleeve portion of the metal annular ring; and the rib preferably presenting locking means, which are embedded in the plastoferrite to prevent the metal annular ring and the plastoferrite ring from rotating in relation to each other.
