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

I took a gamble and bought the cheapest rails amazon had to offer (these) and they turned out better than expected. Very straight, and only one wobbly carriage, which I expected and had already bought quality bearings and spare carriages in case there was a lemon or 4. No perceptible play in the other 3 carriages, for this price point The value is insane. Dont let those gatekeepers on cnc forums tell you you have to drop 500 on name brand rails! Just be ready to send back for replacements if they don't test out well.

This product worked well and it is as advertised. Rugged.

Easy to set up and use. Customer service was totally awesome when I had a question about the product… quick response and very helpful.

I didn’t need it at the end of my projectI returned it and had no issues with it !Great customer service and super Great product!

Parts were damaged and 1 block missing when received. Please send me 1 slider block to replace the damaged one. Need this overnight. The product It looks good meets my requirements other than the damaged slider. Wi be ordinary g again for next project if I get the replacement part.

The rails came quickly and the precision of the rails made it easy for me to build the flattener for my live edge boards and the end grain cutting boards. Great product, and price for my use!

Product is of good quality, rollers are free moving. Perfect for my router sled.

Great product: Smooth and precise operation, sturdy. Used the product to create a sliding sofa/bed on an RV. Be Aware: If you are planing on extending the length of the slider by joining two butt ends together, the tolerances on the ball bearings slider are so tight that it is difficult to line them up and pass the bearings through. Otherwise, that is a testament to their precision.

I needed a way to flatten a very large end grain cutting board. They worked great as the support rails for a router sled. Easy to take down too.

Fast shipment. Well satisfied
