I had a bunch of wheel hubs made that have a 32mm inner diameter. They need to fit on a spindle with a 30mm diameter. I was thinking of getting the below picture made to adapt it from 32mm to 30mm but was wondering if that could cause any squeeking or alignment issues or if theres a better way to do it. Also would steel be the best choice of material? Where would I be able to source this size pipe for some R&D?
Here is another pic for illustration purposes
