IVE HAD THE BEST RESULTS WITH SINTERED BRONZE PILOT BEARINGS
to be MAGNETIC it would need to be IRON

I suppose a roller bearing type pilot bearing could be magnetized, but why? The
magnetic forces would be so small compared to the other forces being applied,
they would be negligible. Nothing to be gained by magnetizing the bearing, in
fact just the opposite. Any metal particles would be attracted and ground into
the bearing during rotation, causing the bearing to fail early.

Thanks for the replys,I just heard that if a magnet sticks to the new pilot bushing not to use it go to a non magnetic one, that are getting hard to find,have a new one here that magnet sticks to and a old new one in stock that's non magnetic.I guess the new one has more iron in it like grumpy said.
Thanks again
