3D Maker Parts MGN9H-1R-300/350/400Linear Rails with Carriages (FINAL SALE)

I bought these for a custom Trident build and after a little lubrication with Super Lube PTFE lubricant they run very smooth. Would highly recommend especially for the price.

Got these on a huge sale which is awesome. They are built pretty well however the grease is super chunky and nasty. So will take multiple cleanings to really get them in good shape.

I picked these up to use for the Z rails on a Voron v2.4 build. After giving them a thorough cleaning, they seem fine for this use case. I actually ordered a second set for another v2.4 build. The bluing, or whatever finish that's on them, isn't great; but they don't seem to be rusting, either.
