So, since I'm no longer withholding...I think the bearing in question is fairly common on agricultural equipment in the form of PTO shaft bearings and carriers. Many a post-hole auger or brush hog I've encountered had one -- but I'm not sure whether the shafts were as large as 2".
Of course, for a mast/rotator that's not under a load (at least nothing like a 540RPM/50HP load) a reducer could make fitting it all together easy enough.
Tractor Supply, a John Deere or Case dealer's parts department might be a good starting point.
