hey, im in the final stages of building bearings for my swingarm. but ive got a problem i wanted to run by yous guys. i have to make the thrust surfaces that will carry the sideload, how ever much there is, on the swing arm. i have a needle bearing setup inside the swing arm, with an inner race that will extend out to the spacer/washer/bearing in question. but i need a thrust washer/surface/spacer for the swingarm. on the stock setup, its the bronze insert that has a flange turned on it that has those cups over them that hold the grease etc in. it also acts as a spacer to center the swingarm in the frame. since im using a seperate inner race, it doesnt have that flange on it. nor can it since it has to rotate in between the mounts in the bearings. so i need to make a spacer that will either carry that inner race, or have it contained inside or in between. in essence, a continuation of the needle bearing, but with a flange to act as the spacer, like the stock setup originally had. i thought about using the old brinze inserts, but ditched that idea. then i thought about buying some silicone bronze, but that shits expensive. so then i thought about plastic. i have a pile of teflon stock that i could make it out of, or delrin. the tensile strength i found for teflon is about 3500lbs. the tensile strength of delrin is about 9000lbs. i already made the parts in teflon thinking there wasnt that much a difference. but i looked it up after i got home and there is. so i guess my question is, think its worth remaking them from delrin? or is teflon good enough? remember, this is sideload on the swingarm at the pivot point. any thoughts?
