I get the impression that ball bearings come in various hardnesses.
Am I right in thinking that harder is not necessarily best?
If you're rebuilding a cup and cone bearing, presumably you would want the wear to be taken by the most easily replaced part - ie, the ball bearings.
If this is the case, how would you set about choosing which hardness of ball to go for.
(The bearings I intend to rebuild are a pair of mks sylvian pedals, so I dare say not really worth worrying about)
Any suggestions or thoughts?
( I am not an engineer, as is probably apparent from this question!)

That's not a recent photo, by the way
I know that balls come in "grades". The higher the grade number, the more accurate the sizing. You need all the balls to be EXACTLY the same size, a big one would take all the weight, or a small one none of the weight.
So it's always best to discard part packets as they're made in batches.
As for hardess, dunno!
