Troy-Bilt lawnmower wheel bushing

Replacement bushing for the 12" rear wheels on my Troy-Bilt push lawnmower. It has a 1/2" ID and a 1 1/8" OD, with a flange on the end. I made the bushing slightly longer than the original since there was room to spare and I don't want it to fail again. I also added some small grease channels.

Troy-Bilt calls these "flange bearings", but I could not locate the OE part.

Update: I would recommend to place a metal washer between the mower and this bushing when reinstalling. That should eliminate most wear.
