Worked for my project
Used this as the z axis to create a small homemade CNC using a trim router. Worked well for my needs and all the bearings seemed fine and the shafts were straight for me.

Leadscrew bent and unusable, one of the 4 linear bearings loose because bearing was missing!
Review of CNBTR Metal T8 Horizontal Lead Screw Set Linear Shaft Optical Axis for 3D PrinterThe two rods are straight and that's about the only positive thing I can say about this package. The rest of the parts seem to be made up of reject parts.The leadscrew is so bent that in the 500mm length it is about 5mm out of straight. Pretty useless.One of the four linear bearings has so much slop you can wiggle it around and it turns out there was a bearing floating around in the packaging. The other 3 are acceptable but noisy.Makes me wonder if this is just repackaged factory rejects. Wouldn't really recommend these.
