Quick question. Does glass-filled nylon have good bearing properties? I
would have expected its bearing properties to be poor, because wear
would essentially cause particles of sand to break off, but I have been
told otherwise. The product in consideration is a ground nylon piston in
a reamed brass cylinder. A little lubrication, but not a lot. Anyone know?

Incidentally, I should add, this is a reverse-engineering situation. I'm
trying to figure out what material a defunct company used. The plastic
layer is transparent with a yellowish tint.
