Can anyone name the material used to create the aftermarket rollers in Cat secondary? I have an application at my work where I need a hard, high impact, low RPM plastic bushing. I thought the rollers I installed in my clutch last year would be the perfect choice.

MMM, I am pretty sure he uses Delrin for his bushings. Delrin is good stuff and on my short list to try. Vespel is psychotically expensive and not feasible for this particular application.

You're right, got it mixed up. Pretty sure the rollers are made out of vespel though.
