Customer Reviews for VEVOR Linear Guide Rail Set, SBR20 800mm, 2 PCS 31.5 in/800 mm SBR20 Guide Rails and 4 PCS SBR20UU Slide Blocks, Linear Rails and Bearings Kit for Automated Machines DIY Project CNC Router Machines

Will use these on a sliding table for my tablesaw. Feel sturdy, not quite as smooth as I would like hence the 4 stars. Should work well for what I have in mind though.

Description dead on

Solid unit, nice price. Should make an excellent rail system for my DIY router lift.

these are very strong and accurate, they slide with ease!!!! I had read some reviews and watched videos on some other foreign rails that said they weren't machined accurately and that it was hard to mount things to the holes in the slides, not my case, these are perfect and all are exactly the same!!!! wonderful product from vevor!!!!

Quality material heavy duty. No flex. Perfect for the job. Would recommend.

Buen servicio quede conplasido ha tiempo y aviation con el rogue del tinbre.

works perfect

Will be buying the longer version of this to build my sliding table on my saw, I bought the 11.5 inch but now that I see what these aluminum rails can do and the weight it will carry I will be buying the longer rails

I added this to a sliding table top that was sliding on dovetail slides, not smooth and wobbly. Now with this the table slides on two solid steel rods and ball bearings. Not totally smooth but exactly what I expected for the price. I'm happy. The shipping was super fast too.
