1x42 Belt Sander Idler wheel replacement

thingiverse

I picked up a 1x42 Rockwell upright belt sander on Craigslist. An old man explained that the idler wheels were no longer available. So, I measured the broken plastic wheel and its bearing and made this. Literally my first design. I printed it with PLA and the bearing fit the bearing housing very firmly, possibly too tightly. I used a bearing/race driver to tap it into place. It works well so far, and hasn't broken yet. The retaining ring's outside diameter could be increased for a snugger fit, but I chose to glue it in instead.
