Gentlemen,
on the address below, you'll find an EXCELLENT ISO fit "calculator". You can find the actual dimensions for any ISO shaft/hole combination and the clearance/interference calculated for your fit selection.
Mabe it's being dificult to find the h10 tolerance because it's not a recommended fiting by the DIN7157. Anyway I can send you the tolerances if you tell me the shaft diameter (the tolerance field is diameter dependent).
Gentlemen,
if you need the ISO fits, post the size nominal size and tolerance here, (like 123H10) and I'll try to help.
Few months ago we had here good discussion about the ISO fits, there are also som "tricks" how to use it. Believe me, it is really good tool if you use it smart.
