The listing is for one rail plus one or two carriage blocks . For light duty applications(such as laser engraver or 3D printer) , it's acceptable to use one rail per one axis. It's most common to use two rail and two carriage blocks per rail for one axis.

    Well packaged/Shipped, but 3/4 MGN12 Carriages were good

    Posted by Ben Powell on May 28th 2020

    I ordered 2 mgn12 linear rails with two carriages each. They came nicely package all separate and in good shape. I thoroughly cleaned and installed the carriages onto the rails; 3 of them ran very nice and smooth. I noticed one of the 4 carriages was much tighter than the others, and would not roll smoothly without significantly more force (gravity and a nudge wouldn't even get the carriage to fall downward). I removed the balls completely, cleaned, oiled, and replaced and still had the same issue. It seems the carriage or the balls were simply not made to spec and the raceway is slightly too tight or the balls too big. Either way, may be a good idea to order extra to find ones that fit well.

    Quality/Fast

    Posted by Keith Davis on Apr 22nd 2020

    I ordered these rails in the midst of the COVID-19 pandemic and I still received them in less than a week. Everybody scream Hiwin rails. These rails were incredible quality right out of the package. Very smooth and could easily travel the rail under slight gravity. I though I was going to have to rebuild them all to achieve this. Out of the four I ordered, two of them I rebuilt likely from dust or packing grease which is recommended for any rail you buy. Great product and I will definitely buy them again for future 3D printer projects.

    Just what I needed

    Posted by brian anderson on Apr 3rd 2020

    I'm building a custom printer and needed some nice long rails. These came in fast even with a global pandemic, and worked perfectly. I've ordered this sort of thing from other sources before and it was awesome getting ones that slid smoothly right out of the box!
