Wanted Looking for Siren Motor Bearings

[Skulldigger]

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


parts motor? or know of a bearing seller who might have these?

Is the shaft machined with a complementary taper, or is a tapered race pressed onto it?

 

[Skulldigger]

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?

Does the bronze-colored portion move or does it remain stationary relative to the aluminum-colored portion?

It is stationary.

 

[Skulldigger]

The brass colored part does not move. I wonder if it is supposed to?

I imagine it's supposed to remain stationary. It looks like you have a sort of hybrid bushing-bearing.
