The reason I ask is because the chain ate away a good half inch into our robot when some bolts rattled loose on a pneumatic tire, causing it to expand and push the sprocket (and thus, chain) into the frame.
For non idler chain runs, we use Glass infused Delrin (use masks when machining this crap, it's NASTY to your lungs!), which held up incredibly well, and never wore down during our whole season.
