Well you would know Roger,  and graphite was my first guess.  Renner 
claims to this day that their research department has firmly established 
that there is no detrimental effects to using graphite... tho I 
experience problems time and time again with graphited bushings. With 
teflon powder available, you'd think there would be an incentive to at 
least offer an alternative... but no.  You can argue your way into 
getting them to supply you with non graphited parts.. but its not the 
easiest thing to do.  Graphite is one of the reasons I generally repin 
from the get-go if I am doing a really  important piano. Too many times 
with too many woes when graphite is involved.

Cheers, and thanks for the clarification Roger
