Nope.
How can you judge idf the axle is the same, apart from the length?
You have to deal with various ball race radius, ball diameters, designed to combine with corresponding cups, contact angles.
Of course, you can give it a try, but the chance is small that it works out perfectly.
E.g.: if it is a BB-set with caged ball bearings, sometimes the cage is pointing inwards, sometimes outwards.
You may understands that those axles / cups are not interchangeable.
@ Rapepper:
I have a Shimano BB-UN90 cartridge type BB, italian thread, 107mm axle length, new. You can NOT take it apart.
Let me know if you are interested.
