So late last year (really late) I hit the curb with my reel mower bedknife

. It broke the bedknife and in the process jammed the reel and busted the reel. It was late in the season and I was basically done mowing for the year.
It's about time to start mowing again so I'm out here working on it to get it back together.
I've got the bearings replaced and put back in their housing and housings back on the reel (wasn't as bad as I thought it was going to be). The shaft in the bearing isn't super tight and it slipped on pretty easily. The question I have is that about the shaft of the reel spinning in the bearing instead of the bearing spinning on the shaft.
For reference part 39 is the bearing and rolls inside of part 40. Since the shaft is not super tight on the inside of the bearing (or doesn't seem to be) I'm worried that the shaft is just spinning within the bearing and not the bearing spinning.
I tried to make sure the grease was off the shaft and not inside the bearing but I'm sure some residual amount was still on it. However at this point I question if it is a concern at all?
Eventually I would assume it would have enough friction after spinning some to wear the grease off, heat up slightly and expand some causing it to become tighter.
Spinning the reel by hand I can't tell 100% sure if the bearing is spinning or the shaft is spinning in the bearing, but to me it's spinning freely with little to no resistance, so it's not like the bearings are frozen or something (all new bearings on both sides).
Should I revisit this? Should I check something else?
