Review on Uxcell 6903 2RS Bearing 1180903 Bearings by Greg Greiner

One bearing feels smooth and one feels rough. I pulled out the gaskets and found that the smooth one had some grease but the rough one didn't. I stuffed them with marine bearing grease I had on hand and reinstalled the seals. They go into the bottom bracket of the bike and so I don't expect long life. Just take a look. If they last longer than a year I will post an update. It's possible that adding lubrication is the key to longer life as they don't seem to have a bad finish and build. fat. It was still rough after being filled with grease, but there may be a small spot of rust that needs to be addressed. Just take a look.
