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 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.

Overall this is a good product, If I were to buy in the future, I would choose the thicker set to avoid slight deflection in the Aluminum support to the steel rods. Performs as expected for the price.

I actually cannot believe that I was asked to write a review for these, since they never arrived. Instead of these rails I received a photo canopy for small item photography and a large food warmer. Then in response to me contacting them to rectify the situation all i got was offers of partial refunds for the problem, and never once was there any indication or offer to send the correct items. I eventually just cancelled the order, got a full refund, and purchased these rails from a different source. Now, it is evident that there is no human presence at Vevor as I was asked to write a review. These are not business oriented people, this is a warehouse pushing out stuff without any means to correct errors. If the same happened to you, do not settle, demand full refund.

Very well made and easy to use. Gliding surfaces are very smooth and operate with little effort. Since the slides are bearing mounted it help reduce router noise from vibration.

Rails were very sturdy and straight. Bearings slide very smoothly. Easy to adapt to whatever you may need it for.
