Abstract
A backing ring assembly is for a railcar axle assembly including a shaft with a central axis and a bearing mounted on the shaft. An annular backing ring is disposeable upon the shaft between the bearing and a shaft enlarged section and has a central axis, an inner surface extending about the axis and defining a central bore for receiving the shaft and a retention surface facing away from the shaft enlarged section when the backing ring is disposed upon the shaft. A retainer includes an annular body, disposeable about the shaft enlarged section and having an inner surface sized to frictionally engage with the shaft enlarged section cylindrical surface, and at least one coupler connected with the annular body. The coupler(s) engage with the ring retention surface to releasably connect the retainer annular body with the backing ring to retain the ring at a fixed position on the shaft.
