Most any medium-size city will have a bearing supply house of
some sort. Try your Yellow Pages first; after that, try a web
search on "bearings" and the name of your state or province.
If even that fails, then just search for bearing sales houses
and manufacturers.

Good luck.

Yellow pages, "motor repair" or "electric motor". Some places 
will even make them for you, machining the graphite to fit. 

Good luck.
