They are indeed IAE V2500's.
The No.4 bearing was the one that gave some trouble during engine development, and has its own oiling system which is monitored by ECAM.
Recently the No.3 bearing has suffered from stress fractures, resulting in IFS.
If this was the No. 5 bearing, then it looks like Rolls-Royce shares will be taking yet another dive !!
Moley.
