I took once again a glance in that FAG internet appearance and those brochures.
I found the - 54 to +120 deg C values you mentioned, and yes, those technical data wouldn´t cover the requirements in an engine at all I assume. So I went on and found this
Schaeffler Technologies | Sectors / Key Industries | Product range
Its general description but at least they state there that they can cover a temperature range from -250 to + 500 deg C.

What I take from the holes in the wing picture is , a big piece did the damage to the leading edge structure and front spar. Thats the big hole. The other, smaller one, where a smaller piece puntured a wing tank, resembles very well the cross section of that disintigrated disk.
The assumed trajectory of these two pieces I think are drawn in that sketch on p.18 of the ATSB report. These are missing I think, and should be somewhere to right side of the flightpath. The big piece recovered seems to have left the engine in the oposite direction. Amazing how far it was thrown away from the flightpath.
