Tried these bearings for a bicycle hub and the dimensions weren't good enough to use. The O.D. was undersized to the point that the bearing could be moved in the seat by hand. The bearing that came out required a drift and tapping to push out and the bearing I ended up using required a hand press to install (both ABEC-3 rated).

I never could figure out their ABEC rating, if they even have one, so I can't say they did or didn't meet tolerance. In my application having a better fit is critical. I don't blame the poor fit on the bearing necessarily since they never claimed to be high precision as near as I can tell and were simply a couple of thousands too loose against the 6002 dimensions.

The quality was acceptable otherwise. Seemed to spin true and more or less freely. They weren't packed with grease but weren't totally dry either, so I suspect the little in there was poor quality and had dried out. If the bearing fits your application I would take the time to pop off a seal, clean and repack them.

I feel they are a little overpriced at $6.51 (what I paid), which is why they got a 3-star rating. They are not an exceptional value nor complete junk. They'd work in an application where a little play is OK or that the design allows slop to be adjusted out.

put my da sander back in action for minimum cost

replaced the bearing in my sander. Sander works again. I'm happy.

Great price.

Great bearing!
