Hi Jerry

The answer is stainless bearing, I get them from Geraldi Bearing, but I 
assume King Bearing or other bearing houses will have/can get them.  Cost is 
a little more, $28 last time I got one.  To date I/we have not had one fail, 
some have 250-300 flights.  Jerry Jay has one that has out lasted the ring, 
put a ring in it last night and he left the bearing in.  I don't know if you 
remember, but this was also the answer with the OS .61 Hanno vs the .61 RF, I 
never did have a bearing fail in a Hanno .61, bearings in the .61 RF were 
similar to the RX 140 (100-125 flights).  You may have to push the bearing 
people a little to get a stainless, but trust me, they are available.  I have 
had poor luck with Boca bearings in general, by the way.
