I bought some replacements at a local bearing distributor. As they told me the original designed ones were hot rolled to create the flange while the replacements I got from them were machined and more precision made. Still after running a couple of years, I had one of those higher quality bearings shatter the inner race. Was a real bear getting in apart as it swedged itself to the axle shaft while under load. When I finally got it apart, i replaced it with the same bearing but I also added 2 non-flanged bearings (and spacers) to back up the outer flanged bearings and spread the loading out. I have my fingers crossed and after 2 seasons it seems to be holding together fine.
