bearing question

[mike mueller]

 Sorry if this has been asked before but who sells metric stainless bearings that are good for our planes. I looked in the McMaster Carr ctalog and I can't find my size in metric stainless. Also should I be concerned with the ABEC rating or will ABEC-1 be ok? Thanks, Mike

             I had it happen with both types of engines, Took more than 100 runs to manifest itself. Plus, when the grease is gone the bearing runs dry.
 
Lately I run Stainless in the 2-c's and regular in the YS's. Use after run oil with the 4-c's and no after run with the 2-c's
 
I do leave the grease in on the sealed bearings - its a different deal...

Eric,
 
Is that on a 2 or 4 stoke engine?  I haven't had any problem on my OS this way so far.  Am I just lucky or is there a difference in bearings and the grease in them.  I installed a bearing made by Bearings Limited distributed by Purvis out of Dallas.  I know of several guys in this area that do it this way.

FYI - the grease will leak. If you are pressurizing from the crankcase it can make it to the tank and the fuel supply. The grease congeals just like snot (sorry but that was the best description available this AM)  when mixed with methanol.  Also it has reached the metering slot in the carb. more than once for me.

Eric.

Emory,
 
Some of us have been just leaving the seal and grease in the bearing.  I had replaced the bearing on my OS and the first replacement bearing I removed the seal and rinsed the grease out of it and just used after run to lube it back up after the install.  Well!!!  this bearing only lasted about 20 flights.  New bearing in now with seals in place has over 50 flights and doing fine.

Hello,
 
I have some replacement bearings for my ST3250 that have the covers over the balls. I think they may also have some grease packed in there. How do I remove the cover to wash it out. Do I just pry it off? I don't want to mess up the bearing.
 
Thanks in advance.
