That post about bearing technologies is a wealth of information. My tech times are so far away - 1st life I usally say - that I have forgotten a lot about the specialities in that field.
Reading your information a question arose: Is it possible that aside of that AP coating - probably used in high performance jet engines - also Ceramic balls are used in such a desighn??.
From FAG information I took that any of their products used in high tech engines is custom tailored and thus probably far away from what they publish in their normal product listings.
If Ceramic balls are used, would that decrease or increase the consequences of loss of lubrication ??
Thanks in advance
