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

Nice smooth functionality.Solid rails bend pretty easily but not an issue if supported correctly.Dust in the bearings may become a problem but am working on a fibrous washer to help with thisUsed on a router planer table for odd wood shapes.

Work fine for their intended use.

I just had these delivered for a fold down table project I'm working on. I need something that is quiet but also had good weight capacity. There isn't a great amount of information in the product description so I went to the manufacture site. FYI - Each slide block can handle a static load of 308 lbs and a dynamic load of 198 lbs. I believe the bar itself can handle much more so using two blocks per bar should easily handle 400 lbs.

Decided to make my own router sled and saw some ideas using linear rails. Got 2 sets and had to cut one set to length. Heavy, sturdy and did the job nicely.

Works well! Using for rail system with my router for a planing table

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.

Good quality steel, solid and no corners cut despite it being cheap, slides well. with simple adjustment can remove any wobble. Really just does it's job.

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!!!!
