Review on Uxcell Bearing Chromium Precision 100Pcs by Brian West

Calling those G10 stocks is like calling a 1994 Honda Accord a fighter. The G10 rating itself is silly, as ABMA cites a ridiculous +/-0.00025mm variance of bullet and batch sizes. Rejection from these guys? Probably closer to +/- 0.04mm. These are two cold orders. If they were at least G10 level I wouldn't even have the necessary tools to check them. Instead, a pair of cheap calipers (or my damn eyes for some of them) will be enough to spot any spherical aberration or surface pitting issues. I used these bearings because every time one of these bearings rotated the whole damn thing would seize up. If you're working on something that requires a certain level of precision, don't waste your money or, more importantly, your time on it.
