Do you mean they are Stiff to get on screws.? Or the bearings are pressed into the BK block.? If just stiff to get on screws then yes this can happen, just give the screw light rub with emery and they'll go on.

DONT REMOVE the balls WILL fall out. If you want to remove the Nut then you need tube the same size as the minor diameter of the screw and then rotate the nut onto it.
