I don't see anything particularly unusual in the picts. Just that one side has a failed bearing, ie the cage came apart. No biggie, just replace the bearing (s). If it were me, I would say hopefully with old, original parts, even select used if you can find a matched bearing with its original race. If you must buy new, be careful with the shimming process - I've read here that new bearings might have dimensional variations??
As far as I am aware, I don't believe there is more than one carrier bearing, for 35 to 48.
