Customer Reviews for VEVOR Linear Guide Rail Set, SBR20 1800mm, 2 PCS 70.9 in/1800 mm SBR20 Guide Rails and 4 PCS SBR20UU Slide Blocks, Linear Rails and Bearings Kit for Automated Machines DIY Project CNC Router Machines

I see a lot of reviews on these sub level 4. Folks your getting \"good accuracy\" for a VERY CHEAP price. If you want betting quality, guess what, it costs major bucks! To Daniel with the router sled, you installed them upside down. The axial load is at its least support the way you have it. I suggest buying the 20mm full bearing SBR20 Linear Slide Rails instead. These are VERY good quality for the price.

Good bearings, made a router sled rolls easily and smoothly on the rails. Bearing blocks use four 6mm screws. I lasered a mounting plate from 1/4" acrylic to mount the Vevo rails.

Very good quality, packaging was excelent and super fast shipping.. I am using them for a lift bed system and it works great!

I have purchased several items from Vevor and have never been disappointed This is my second order and all items work great Thanks Vevor for the fast shipping and excellent products

These have worked great for my router sled I built to flatten slabs. I am soon going to be purchasing more for another project!

For two rods four bearings and four clams you really can't complain I spent less than $100 on 2 sets of 20mm x 1200mm but 4 bearings are a bit sloppy 2 are perfect and 2 are way to tight

Item was delivered on time. These rails are heavy and the box they were delivered in was thin, cheap, and very damaged. The rails arrived with missing parts. Guessing the parts fell out of the holes in the box somewhere down the line. I initiated a replacement and it came as expected. Rails work as expected.

Box in shipping was fine. No issues. No missing parts. They don't glide as smooth as had hoped, I adjusted the tension and some are smooth and others not so much. Overall, I'm using it to make a vertical drawer slide and it should do the job.

I love these Linear Rails! Perfect for my Router flattening jig. I think I am going to longer units for another table that I am making!

The rails and all.of the manufacturing seems.very nice for the price point. Had a couple issues withe the bearing blocks but customer service took care of.
