iceturf I have noticed similar problems with my order - regretful your review wasn't posted sooner. I ordered 4 of these, one of my leadscrews is bent by ~0.63mm. I also noticed that the bearing blocks are stuffed with the wrong bearings and the BK10 bearing blocks don't clamp the bearings properly - they slop around, the bearings are 19.91mm and the space for the bearings is around 16.08mm, around a 0.17mm different. Since the bearing blocks are also wider than the bearings, ~26.06mm vs 25.99mm.

iceturf I noticed similar issues with my order, issues with the bearings (not angular contact), issues with the bearing block (0.17mm gap for the bearings to slide back and forth in, add ballscrew backlash 0.17mm), one of my leadscrews was bent by 0.23mm. Terrible quality.
