In my experience using Evaporust it has no obvious effect on un-rusted steel surfaces. If the ball bearings are not rusted it shouldn't effect them, if there is rust on the ball bearings or the races they run in that's a whole different situation. Then the rust will be removed and the underlying damage to the steel itself will be exposed.
