I’d say no.  The is no metal in there that is going to be damaged by 350F.  350C would be another matter.

As I understand it, the whole issue with keeping the oil temp below 210 is to keep from melting the bearings.  While most of this oil cooling is from oil being sprayed on the inside of the rotor, isn't there also a layer of oil constantly being pumped past the bearings themselves?  This must help cool them some directly as well.  

 

350 still sounds kinda high.  Maybe I can take the bad rotor, and put it in the oven (when my wife isn't home of course).

 

BTW, I would like to apologize to those of you who are now beating your heads against the keyboard screaming "just change the damn bearings"  :-)
