Don't forget that these bearings expand in service; possibly from the
lubricant used by you, but certainly from moisture uptake. Tufnol quote 3%
expansion in the fully water-saturated condition.
The point being that if they are set up too "carefully" (i.e. with only a
small amount of axial end-play) then they can later go tight.
