To make the idler sprockets on our lift it took a little tinkering. We used a vex plate sprocket on a flanged bearing. Then we made spacers our of 3/16" aluminum by cutting a circle with a 2" or so hole saw, and then cut a 1-1/8" hole in the center of that. Those spacers took up the extra space on the surface of the bearing so that we could use a washer with 1/2"id and a clamping shaft collar to hold it all together. It just makes a sandwich of washers basically that allows the sprocket to be forced to stay in place but can still spin freely on the bearing.
