Customer Reviews for VEVOR Linear Guide Rail Set, SBR20 1200mm, 2 PCS 47.2 in/1200 mm SBR20 Guide Rails and 4 PCS SBR20UU Slide Blocks, Linear Rails and Bearings Kit for Automated Machines DIY Project CNC Router Machines

I used two sets of these to build a flattening sled for a router. These are very precise and strong, end result works beautifully.

These rails are good quality and worked out prefect to make my own slab flattening router fixture they are straight and the bearing saddles glide smoothly

Time between ordering and delivery to front door was excellent. Had product within a week. Product is of excellent quality, price was unbeatable. Will make flattening much much easier and quicker. Thank you.

These linear rails were perfect for the big project we just completed. It was easy installation. Thanks Vevor!

I purchased the guide rails to custom build a router sled in order to match my needs. I'm still setting the tabletop but for now, everything looks great at a great price

One of the rails arrived slightly bent - its base has a minor amount of wobble when placed on a flat surface - and the sliding blocks' travel mechanism is quite flimsy overall - made out of a fairly fragile plastic encasing the ball bearings. However, for the price, not a bad purchase. We'll see how it holds up over time.

Perfect hardware for what I needed for constructing my own Router Sled... Good quality, Reasonably Priced, and easy to use.

I was surprised at the weight of these flattening jigs. Rods are solid chrome plated steel. Perfectly straight and really easy to roll. Clamps appear to be aluminum with steel ball bearings inside. Shippment arrived with hardly a scratch to the shipping cartons. I will use Vevor again.
