the sealed bearing wheels are pretty easy to work with and as SPB says there is likely just a little play. they do still have a thing that acts like a cone, depending on the model.
alot of the olde cartridge BBs just take a little time and patience to work with but most can be done with a bit of effort, a block of 2x4 and hammer
