They don't make 'em like that any more...

As I said, there's no such thing as "a bearing for a $machine" - except 
in very unusual circumstances.  Every bearing is made to a given size, 
and machinery manufacturers pick one that suits their needs.  For 
example, I discovered that the ball races that form the timing belt 
tensioners on my '79 Citroen GSA (two, one for each head) are also used 
(only one though) on Fiat Tipos as timing belt tensioners, Zetor 
tractors as a gearbox shaft bearing and Bosch washing machines as a drum 
bearing...
