You might be able to do like Myford do on their countershafts and use two bushes with a small gap between them and an oil hole going into the gap. Thus oil gets around the full diamter then into the bushing frm there. In your case instead of one 25mm long bush, you might use two 12mm long bushes with a 1mm gap between them.

That's an ideal approach for several good technical reasons, as well as probably being more economical.

P.S. … Phil: I should have mentioned that your proposed machining is NOT the preferred method … Please read the guidance before you decide how you're doing this.
It's rather buried in the Bowman site, so this direct link might be useful:

[There is a companion one for flanged bearings.]
Choose an appropriate size for the bearing and then look at all three tabs.
