How can I calculate the radial stiffness of ball-bearing?
I have found this formulae
k=b*d+c
where
d: diameter
b=1300 for ball bearing
c=62500 for ball bearing
A 6008 bearing has therefore a radial stiffness of 114500 N/mm.
Is this a realistic value?

Assuming that the formulae is correct, it seems to be a simple calculation. However, care should be taken on the units. it is not clear what is the unit of b, c, and d. Usually, the unit of stiffness is N/m in SI. So care should be taken in the conversion of m to mm and vice-versa. Thank you.

That is a good question. I have found better model like those provided by Rtiwari that seems to be much better, or the ISO/TS 16281.

What is the "b" and "c".
What is the source of the formula?
How to arrive at the value of "b" and "c" ?
For the Diameter "d" which value need to be considered, Bearing Internal Diameter or External diameter ?
Kindly clarify the above, Also If possible kindly share the document which explains how the bearing Stiffness is
k = b*d + c
Thanks and Regards
