Customer Reviews for VEVOR Linear Guide Rail Set, SBR20 1200mm, 2 PCS 47.2 in/1200 mm SBR20 Guide Rails and 4 PCS SBR20UU Slide Blocks, Linear Rails and Bearings Kit for Automated Machines DIY Project CNC Router Machines

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.

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.

prodotto rifinito ok!

Not the best linear rails, but with some adjustment, they turned out to be very good. A little noisy, but perfect for my applications.

The blocks could be better cast with better cut threading but overall seem to be pretty straight and strong. Using as guide rails for 10mm thick 410x410 aluminum plate for custom 3d printer. So far with about 20 hours of use on them they have tracked fairly well.

Sturdy assembly, no bend or sway... Performed as advertised.
