Uxcell Shielded Groove Bearing A12021500Ux0294 Review

Purchased for band saw blade guides where they have had limited use. They've been fine so far. The gaps are free. I suspect they won't work well in a more demanding application.

This tiny invention saved me $300 on repairs on my professional Tour de France bike. They wanted to replace half the parts on the bike, but after replacing a bearing, it ran like butter and sounded like a samurai blade slicing through the air.

well those are bearings, round and true to size but that's it. They have quite a lot of gameplay and gameplay varies between different ones. All have the inner race moving several thousand inches relative to the bottom bracket. I bought to replace a bearing in a cheap Chinese saw thinking they would be good enough but I was wrong. The new bearings were almost as bad as the worn ones I replaced.
