Befenybay 6PCS Diameter 8mm Black TR8x2 Lead Screw Nut for CNC and 3D Printer Parts (Size: Tr8x2)

I used these to replace the worn brass lead screw nuts on my Anycubic Mega X. They are perfect fits, and a little quieter than the originals. I do recommend that you put some lube on the lead screws to minimize wear, but that would be for nay lead screw nuts.

Worked!

Super quiet, barely any play compared to brass nuts. These fit my 3d printer perfectly. Z movement is not loud at all. I hear the motors themselves way more clearly over the lewdscrew nut.

These make a good update to help eliminate the need for lubricant and eliminate noise. They are a little sloppy - a lot like the brass ones. I think a little higher precision would be ok.

For the pitch specified, these are great bang for the buck. Slapped 2 of them right onto my Anet A8, but I had to drill new holes for the Ender 3. Cest la vie, cant keep it cherry forever.

It didnt make my machine as super quiet as i was hoping (i have another rail somewhere thats causing some buzzing/squeaking noises), but they did quiet it down a bit, and i feel like everything is actually running more smooth. Never used the plastic nuts before, but i dont think id go back to brass now

Ender 5 plus is no longer squeeking after installing this.

Tight fit, no slop, perfect for my needs

Got these for my new ender 5 plus. Fit great and took away the screech it had developed when lowering z axis.
