## Main Question or Discussion Point

Does anybody have a table of rolling friction coefficients? I can't find the one I'm looking for. I have a vertical door opening (similar to a garage door) where there are UHMW polymer rollers rolling in a track. I read somewhere that the coeff of rolling frict would be close to teflon on steel... but I can't find that either.

Any help would be appreciated.

Thanks in advance!
