Double Interference Fit

Double Interference Fit

Double Interference Fit

Hey guys,

I am designing a bushing that will hold bearings. To understand my situation please open the attached file while reading my post :). So I want a bushing to be as universal as possible and able to fit with several different bearings. To do so, depending of the bearing I want to install, I will before press the appropriate sleeve in the bushing and then press the bearing.

However, I have never done a "double interference dimensionning" (I just created this term, maybe there is an official one) and I wonder how to tolerance the bushing and sleeve diameters to make sure it will always fit, because when the sleeve will be pressed, in ID will be reduced.

Hence, my question is:
-Is there some kind of litterature that talks about that kind of situation (I take a look at the MH26 and found nothing) ?
-If not, do I have to calculate the lateral strain using poisson's ratio or do I simply take a light press fit ?

Additional infos:
-This bushing is use to fasten a mountain bike fork
-Bushing and sleeves are made of aluminum
