Out of the 10 pieces, only 8 were usable. Unfortunately, I used 7 in my assembly and those are working fine, it was not until I tried to use the other 3 did I notice that 2 were defective. It appears that these are assembly by installing the spring and ball then crimping the end to lock in the ball and spring. Well, 2 of the 10 were crimped too far/low/deep and the ball does not protrude far enough to be usable.

Needed these for a 3D printed project. They’re very hard to find locally, and expensive. Was able to find them easy on Amazon. Shipped fast, and have been working great

These are well made, my only issue is how strong the spring is. For a metal on metal application they will work nicely, in my case I was planning to have these press into detents in a 3d printed part. Even if I use really tough plastic I wouldn't expect it to hold up to the pressure of these ball screws.

As advertised, good spring pressure on the bearing.
