can some kind person ( or an unkind but helpful one ) , please advise me on choosing the correct tolerance for a shaft and bearing housing
i have a 300 RPM shaft running on 22212E ( spherical ) and 3212 ( double row angular contact ) bearings.
what machining tolerance do i use ( H7 / N7 / M5 etc etc ) to get the following ;
22212E outer and inner race moderate interference fit .
3212 outer race interference fit , inner race able to slide on shaft under light force from a locknut.
There is light vibration , 4000 N radial load and light intermittent axial load , the housing is heavy wall K1045 and shaft is 4340.
22212E bearing is 110 OD x 60 mm > > > 109.97 housing x 60.02 shaft ???
3212 bearing is is 100 OD x 55 mm > > > 99.98 housing x 55.0 shaft ???
any helpers please ?
