I believe those are INA numbers for a FAG bearing. Check their website.

Dear ,

Sorry for the late reply I was on site ( wind turbine ).

It was from INA I think .
After a discussion with INA , they allow me to have the characterics.

Here is the information :
   BPFIBPFOBSFFTFrolling element
555086INA 17,2914,716,180,4632,0
555087INA 16,2713,735,860,4630,0

I was wondering why is the Outer Race Frequency higher than the Inner Race?
