Web7. SKF bearing cage failure frequency (FTF) usually does not appear at its fundamental frequency; 8. When the rolling element itself fails, not only the rolling element failure frequency (BSF), but also the cage failure frequency (FTF) will often occur; 9. When the SKF bearing frame breaks, the rolling element rotation failure frequency may ...
