Customer Reviews for VEVOR Linear Guide Rail Set, SBR12 1000mm, 2 PCS 39.4 in/1000 mm SBR12 Guide Rails and 4 PCS SBR12UU Slide Blocks, Linear Rails and Bearings Kit for Automated Machines DIY Project CNC Router Machines

Everything you'd expect. Straight, clean rails that are working perfectly to support my router sled. No problems or complaints.

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.

Hubby is happy. They're doing the job nd he'll be purchasing more.

Used in the fabrication of surface planer!!!

Looks like a quality product that will do the job for a long time. Fairly tight tolerances.

I got this to make a flush cutting jig for my hand router. I was able to cover a cutting board 18"x20" and level both sides in less then 20 minuets. This made the best jig I could ask for it slids very smooth in both directions. I was able to level both sides that I used to take hours tring to level by hand sanding. The Sbr-16 bearing blocks work perfect but they are a little tricky getting them to slide on the rail the first time. I hand 2 that just did not want to go on and I hit them on and some bearings poped out. I was able to snap them back in place and aline the block again on the rails. Its a learing experience for me making this jig with these rails but no regrets. I even ordered me 4 spare bearing blocks. to make more jigs to run on these rails.

I bought 2 different sets of these. For making a router sled and they don't come with screws. So I had fun trying to find the correct size and there aluminum so easily stripped out. It it were not for them not coming with the bolts for the slide blocks I would recommend .

Used to upgrade a DIY wood CNC router. So far they seem like they will work well.

So my intial order was wrong and was missing pieces. Had to return it and got a new one. After receiving it I was able to build my linear rail router sled. It was smooth and easy to assembly. Great overall product

I have bought these with the idea of making a sliding shelf on our bed so that on remote days and sick days my wife can do her work from her laptop in the bed and when not in use the shelf can slide to the foot of the bed out of the wayI have installed the rails and they work great I will be build the shelf and attaching it next weekend
