A rolling tool for deep rolling fillets of crankshaft journals is provided. The rolling force is divided and spread by the back up roller and directed onto the laterally spaced side shoulders of the workpiece roller. The fillet rolling forces are then recombined and directed into the fillet by the workpiece rollers which works and compressively stresses the fillets of the pin journals. With the rolling force between the backup rollers divided, there is reduced workpiece roller wear as compared to prior art backup roller designs.
