Great Deal! turnkey set.

All components exactly as pictured. Bearings are smooth and tight. Flex link has excellent flex with low lash. Packed in a cardboard tube.

As described

Great packaging, was what I was looking for my mpcnc

and of a nice quality. They work nicely on the 2D printer ...

The follower Nut needed to be worked a little to remove some small machine burrs, but the bearings, and coupler fit and work well together. The Threaded Lead Screws are straight, properly threaded, right thread pitch, and of a nice quality. They work nicely on the 2D printer that I am building.

Very precise I love these lead screws best I've found so far

As advertised

Great for the z axis of 3d printers

Received everything pictured. I used them to upgrade the z axis of my 3d printer, so I didn't use the nut. I used anti backlash nuts instead. They have 100's of hours of use and are working flawlessly.

Great Value

Screwed-up our CNC project just right!

Highly recommend!

Great product and super fast shipping!

It came without the lead screw, BUT!

It arrived incomplete BUT the costumer service is great! and they have send the screw. The copper Nut, coupler and Pillow Bearing Block work fine and they are a good quality product.

Five Stars
