4PCS SK10 Aluminum Linear Rod Rail Shaft Support Guide Motion for 10mm/0.394" 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.

No issues receiving straight rods. They worked perfectly for my application.

Great

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.

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

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.

Fit perfect exactly what I needed to finish this project

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

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

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

Product quality look great, just as advertised

it would require quite amount of torque before it starts biting the linear rod. now, when you want to loosen it, the hex key head just deforms and say goodbye to the 6mm rod you bought for it. now i wasted one of the 2 rods i bought. you can try some grinding compound but the screws would just start to chip away till its round. i had some stainless m4 screws lying around and replaced the rest and it works perfectly. all and all, wasted time. wasted resources. im just so frustrated right now.
