Any recommendations for a hard roller material on an extrusion?
 

Hello,

I'm trying to make a roller system where I have some wheels supporting
a load and rolling across an extrusion. I am trying to minimize the
deflection of the wheels under load. Any suggestions?

Thanks,
Mike

You caould try a track roller. See http://www.mcmaster.com/ and go to
page 997. They have a hardened roller and come in a variety of sizes
and materials.
