Roller Bearings and the Y6-b

 I'd like to throw another possible reason - roller bearing rods have large hubs and may have interfered with the clearance limits on  the lower part of the N&W's load gauge.  With the Y6's 58" drivers and 32" stroke, there's not a lot of room  for a roller bearing rod hub.  IIRC, load gauge interference was a problem with the P&LE's 2-8-4's and they had conventional solid bearing rods and 63" drivers.
