You might check a web search for a local bearing supply house- Mike Hanz 
pointed me in that direction years ago and it's been invaluable advice.  
There's one in Greenville near me.  Brought them an old bearing, told 
them it was for a high-speed electrical motor and they've matched it 
successfully every time.   When I lost some of the tiny bearing balls 
from a reduction drive assembly, I brought them one of the balls and 
they had loose replacements.
