[b] Friction COefficients [/b]

[ariky]

Hello Everybody,
I am looking for data about static/dynamic coefficients of friction between rubber and steel (low-carbon) for dry and for oily conditions.
Untill now I was able to find very little information.
I'll appriciate if you could either direct me to any web-site that contain this info or post the relevant pages.
Regards,
Ariky

Rubber doess't have a single CF. It depends on temperature and other things. Here is a link that shows ways to compute it. Scroll down to friction measurement:

ariky;

I'd be careful using values from a published table. There's so many things that come into play with friction between those two metals (surface finish, normal pressure, other conditions) that any kind of 'general' table is, in my experience, usually way off. A good paper (pdf) on these difficulties and subtleties is at
