Linear Motion Rods 2PCS 8mmx 350mm (0.315 x 13.78 inches) Case Hardened Chrome Plated Linear Motion Rod Shaft Guide for 3D Printer, DIY, CNC - Metric h8 Tolerance

I had no issues with them and they were shipped fast and on time.

I live in a highly saline environment that corrodes all "stainless steel" but im happy to say that these are withstanding that crossive atmosphere granted that I have it coated in a light venere of grease, the bearings run along with no binding and the travel is predictable and reliable

Used foir 3d printer

Headline says it all.Packaged ok, good condition, no issues there, but it's worthless to me as is. 35% price difference between what I ordered vs what I received, to fix their mistake it cost me an additional $33 and 4 days time.Edit: The 2nd set came in, and it's equally as wrong.Save yourself the headache and buy from one of the many other sellers selling these.

Well made, very straight and smooth

Totally met my needs. My only comment is it seemed I had to order a pair of rods even though I only needed one. I would be better if there was also an option to purchase just one instead of a pair.

I bought them to do some custom 3D printers and these work perfectly for my usage.No bends, no dirt or marks or flat spots, just what I wanted. You wont be dissapointed.

put on machine

I used these rods to refurbish Y axis assembly of my Prusa MINI and so far they perform fine. They arrived in a sturdy cardboard box, which I appreciated, except both rods were in one plastic sleeve, thus touching each other. It would be better to have the rods separated to prevent any potential damage to precision ground surfaces. Luckily, I didn't notice any damage, trimmed the rods to proper length and they work fine so far.

I am using these to build a router sled, not working as planned but it was my problem.

Bought this to mount a laser sight for my metal saw. Drilled it out to size, works perfect.

Pas d’hesItation pour en racheter si il y a besoins.

Worth every penny.
