Rear wheel bearing issue - Hole too big, bearing falls out..

[antman]

Well I was in process of replacing the final drive and I took a look at the rear wheel bearing before I put the wheel back on.  Good thing because the bearing under the final drive flange is sloppy as hell.  The bearing is great but the hole the bearing is supposed to be pressed into is too big....  According to my measurements I now need a 48mm outer diameter instead of the stock 47mm.  (width is 14mm, and inner diameter is 20mm).  I haven't found a good supplier.  McMaster Carr only had standard metric sizes, and no odd ball ones.

Does anyone know of a good odd size bearing supplier?    Or is there a way to take up the 1 mm clearance and still use the stock bearing?  

Thanks in advance,
