Review on 🏃 High-Performance Marathon Precision Ball Bearings for Enhanced Efficiency by Aaron Lewis

I ordered these bearings to replace the bearings that came with a Marathon 11x4.00-5" runflat tire on wheel that I ordered for my Troy-Bilt Mustang 42" Zero Turn Mower . The wheels are great, but in order to fit them to the narrower Troy Bilt front wheel, the hub needs to be cut or sanded. I didn't quite get them right and had to knock out the bearings for extra grinding, which eventually damaged them. These replacement parts came quickly and were inexpensive. I put the seals on them as some other reviewers had suggested and added more quality grease to the bearings and then put the seals back in place. The bearings spin easily and hopefully last a long time. Being careful not to abuse them by reinstalling them (after lapping the hubs some more) and with the addition of the lube I made they should be well lubricated. So far my mower is running well with the new bearings. .
