  • NOT for painting! They will rust within 6wks
NOT for paint! They WILL rust in your bottles and eventually ruin your paint! Do not believe prior listings.. cause now I'm out paint and a bottles. IIf these rust in paint mix with only 10% water.. I'd wager they would rust anywhere moisture is present. Very disappointed.

  • Used for bicycle crank-good quality & value-delivered fast!
I had to replace the bearings on a stationary bicycle. I'm a former mechanic so DIY and very happy with the results. The old bearings had "shelled" apart-and there are questionable quality bearings out there. These passed my rudimentary hardness testing but time will be the test. As always proper installation is a key-snug bearing tight & turn back till no resistance or play is felt-then lock the adjuster. And generous quality lube-done forever I hope. ... show more

  • Plenty good enough.
Didn't need this many but now I've got spares ;-) My application is not typical: I'm using them as joints in a welded fixture so can't speak to their accuracy but they do what they're intended. Would have preferred them in crs but that's unobtanium.

  • Science
We used these ball bearings in a Science classroom experiment and they were just the right size. I realize this isn't your normal review but as a Science teacher, the speed of the shipment as well as the item being just as described, was very helpful!
