I sent them an email. Pat, at Anaheim, knows about this bearing and he has a source for replacement bearing. He didnt share the source or part number. He wants $40 each, but the shipping to the opposite coast is going to make it cheaper to go with the new N307LOE I already have and use arbor shims to shim the extra gap.
I have ordered some .020" arbor shims from grainger. I am going to try to use two of these arbor shims to take up most of the .042" gap.
