Customer Reviews for VEVOR Linear Guide Rail Set, SBR20 1000mm, 2 PCS 39.4 in/1000 mm SBR20 Guide Rails and 4 PCS SBR20UU Slide Blocks, Linear Rails and Bearings Kit for Automated Machines DIY Project CNC Router Machines

Exactly what I expected. Ball bearings are low quality, but was to be expected.

Worked exactly as I expected

Nice piece of linear rail kit. I did tried it as it is, it works somehow, but the sliding blocks need to be cleaned. I'll soak them in metylated spirit for 1 day and a proper silicone grease after that, hopefully it will work well.Unfortunately there was a delay in the delivery, due to Christmas and Brexit, but that's not the fault of the supplier.Overall happy with it, I got 2 sets.

Perfect for my project :)

Didn't require cutting. it just fit in the Snapmaker 2 350 enclosure. The cnc setup needed support for CNC operations. The rails are over kill but only needed some spacers to support the platform and prevent it from sagging under vertical loading. The 4 stars are because the holes are damaged perhaps from a botched drilling operation. For this application it doesn't matter.

Ottimo prodotto prezzo economico

Works well to level live edge slabs

Got what I paid for and what I expected. They were not straight right out of the box, but loosening and then re-tightening the mounting bolts helped straighten them enough for my small hobby diy CNC.

Bearings are a bit rough. Rail is straight and true until the end screws securing it to the rail. The rail bends up a little on both ends. Side to side is good.

Worked great for my router sled.
