I tend to think that if the bearings have a decent crush on them like 50 or 6 thou they will handle the pin being tightened on them. If you are a bit nervous about it the way to be sure is machine up some top hat bushes.Just rebate the bore a bit so they sit flush.I've done a lot of them. Machine them out of 4140, oversize. Bring them to a red heat and quench them in oil and final machine them with a ceramic tip. I have a number of machine with them and they are going 7 to 8000 hours no worries.
Steve,an O ring around the outside is good. We also cut a groove in the end cap to take an O ring. It bolts up against the end of the bore and acts as a seal to retain the grease. I might have a pic somewhere.
