interaxial quotation holes with letters

[Fabio24]

Good morning to all, I got a doubt seeing some drawings of our client. is it correct to quote the interaxes of the holes in a plant view with the tolerances indicated with the letters type js or is it not allowed? I tried to find but I didn't find any information about it. Thank you very much

js, followed by a number hopes, is a reference to tolerance as another. So it's okay.
between putting js, or h7, k6, f8, etc. and put +-0,2 or any other figure there is no difference.

I meant a number. I thought it could only be used for male/female couplings. Thank you.

All quotas can be tolerated freely.
Keep in mind that gears are a standard js6....js7.
