| Where interference fits are achieved by pressing
a shaft into a bearing or a bearing into a housing, particular care
must be taken in dimensioning and tolerancing mating parts. Radial
play values of will be reduced by an amount proportional to the
interference.
∆rf = ∆r-fp •
I where: ∆rf = final
radial play after pressing
part
∆r = initial radial
play
fp = interference
factor
I
= interference between bearing and mating part
The interference factor fp is dependent on the thickness of
the bearing ring and the material and geometry of the mating part.
It is suggested that the following empirically determined values are
used:
