Just as a side note which may or may not be relevant,
on my CPP roller bearing kit the inner bearing race is fixed/non removable part of the roller bearing, it has a extended shelf machined on it that the seal rides on. My inner bearing would not slide on the polished clean stub axel (was ever so slightly too tight to slide on the axel stubs). As I test fit it all when dry/greaseless I taped off the bearing rollers and used a brake cylinder hone inside the bearing race to get each side to fit “just so”. (short bursts and kept checking to it until just slid on lightly oiled axel only when perfectly aligned).
