I had a similar problem with my RP's rear crankshaft bearing, although I know that the old one had spun on the rear journal. My new bearing was no more than a good push fit on the crank, so I used some Loctite bearing fit to secure it.No problems is the 8K or so miles since this was done.
I know that there are some members who don't like Loctite as it can make the rear main difficult to remove again. However, Loctite is destroyed by heating to about 300 degrees centigrade, so warming the bearing inner race with a blow torch should release it.
I used a 'crowded roller' replacement bearing from Seven Workshops (See my thread from April 2019 entitled "Rear Main Bearing") so, when the outer track is removed, all the rollers will fall out enabling the crank with the neer track to be removed and dismantled on the bench.
