| 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:
