Replacement Pulley for a Delta 31-050 1x30 Sander

Both of the pulleys/rollers/drive wheels on my Delta 31-050 grinder/sander failed (one exploded) So I modeled up some replacements. Nothing special, just going off the measurements, the originals have a curve, but the design is flat. In the original the bearing is either captive or glued. So I just glued the pulley to the bearing.

They are no longer available from the manufacturer, the original part number is 1341629
