Abstract
A novel two-piece backing ring assembly for a railcar axle is presented. The backing ring assembly has an annular body affixed to the fillet of the journal and a locking ring for further affixing the annular body into position on the journal. The locking ring has an inboard end affixed to the dust guard of the shaft and an outboard end for engaging a slot in the annular body. The locking ring assembly may be retrofitted to older generation railcar axles to increase the structural rigidity of the bearing assembly and minimize fretting wear caused by railcar axle deflection.
