Looking for a front bearing for a Sireno motor. It is 1/2" dia and 7/32 tall. The ID fits a 3/16' shaft. What makes this one difficult to find is that it is a tapered inside bearing as you can see in the photographs. Anyone have a Sireno or similar

The shaft has a taper where it sits in the bearing. I found a bearing the same size but not tapered and it fits to tight in the housing. I have to back the rear adjusting bearing out almost all the way for it to be loose enough to spin.
 
Does the bronze-colored portion move or does it remain stationary relative to the aluminum-colored portion?
 
I imagine it's supposed to remain stationary. It looks like you have a sort of hybrid bushing-bearing.
