4PCS SK8 Aluminum Linear Rod Rail Shaft Support Guide Motion for 8mm/0.31" Diameter Shaft

I used these as part of an upgrade to a 3D printer I have. they were smooth to the touch and dead nuts striaght. function has been perfect.

I use these for my big 3d model prints and they are always reliable and fit perfectly without an issue.

size measures nearly perfect to size bought through entire rod, straight and solid, use it on sanding jig for fishing rod cork handles i build and it works great.

Great

I bought these to repair a Bergeon watch waterproof tester that originally had an aluminum rod that had corroded. I figured to upgrade with stainless. I had to cut it to a shorter length no problem I thought took it to my bandsaw. All the blade did was make a small scuffed spot. Had to cut it with an abrasive wheel. Then I had to drill a small hole in the side for a tiny roll pin. I destroyed several cobalt drill bits before giving up and tig welding a bit of rod on the side. The rods I got were perfectly straight.

These rods were precise and accurate. No issues at all.

Fit perfect exactly what I needed to finish this project

Used these to modify my cnc machine to extend the length of use for my needs.

Beautifully made to good tolerances. My project was more successful because of finding these good quality shafts.

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.

très bon produit

need to make the hole youself in the end of the bar
