The bearing that was used is the same one in a 4" electric forklift wheel, bearing #6204 2rs. The issue we had yrs ago with the manufactures was the lack of grease in the bearings. It wasn't every bearing, just a few out of a group of 100. They would fail within a week of install. Once we decided to repack the bearing with high temp red grease all problems stopped.
Just a side note S6204 2rs is the ceramic bearing, 5204 2rs is the double row bearing and I still haven't found the double row ceramic yet. But I don't think the double row was or is a good idea (personal opinion) because the they are actually weaker do to the fact that they can't load as many bearings in it. bearings can be found here

I'm doing my clutch next month and have an idea I can do this bearing project for less than $150 out the door. I will be using this bearing 6204 2nse and leaving the seals on after repacking it with the high temp grease.
