In simple terms stainless is weaker than plain carbon steel and far 
weaker than higher alloy steels like 4130 (Chromoly).  Most alloys like 
the common 300 series tend to gall badly, but this would not really be a 
problem in this application as you have bearing inserts to deal with the 
sliding.  I don't have the numbers in front of me, but I seem to 
remember that it is not terrific in impact loading either.  That would 
tend to be a problem in this application.

I am with you on the 4130 or similar material.
