Review on Enhance Precision and Smoothness with Uxcell LM10UU Linear Bearings Length by Warren Hess

I built the Hypercube Evolution using 2 lm10uu for each side of the XY link. When printing the bank, the Y-axis suddenly started shifting, forcing me to stop printing. I removed the rattling bearing and opened it up only to find that one of the ball bearings was broken into pieces (see picture). Upon closer inspection, I found that the other 3 are also rattling. Maybe just this batch because I bought lm8uu from the same seller and they work smoothly on the X axis. Maybe avoid lm10uu
