You need to use localized GD&T. For the bore, you can dimension the full ID/OD nominal size and then apply a feature control frame indicating the tighter tolerance specifically over the bearing fit length. You can do this with a “zone” or “length” modifier, often noted as “L = 15 mm” next to the tolerance frame.

The rest of the bore can have a looser general tolerance, and you can either leave it at standard machining tolerance or specify it separately. Just make sure the tight tolerance is clearly flagged with a note or GD&T callout, so manufacturing and inspection know exactly where it applies.
