Customer Reviews for VEVOR Linear Rail Slide 2PCs 20mm x 300mm Linear Bearing Slide Set with 4Pcs Block Bearings SC20UU+4Pcs Shaft Support Linear Shaft CNC Parts Kits for Electronic Equipment Guide Bar

These rails work just fine for low precision applications and slide fairly nice.

The rails are wonderful and work as described. Quality piece. Would have been nice if screws were available as I had to go to hardware store and purchase screws. Also, I would have liked is if the Router Plate was made available, a plate with drilled out holes that match up with the rail slides. If I missed something, please respond back with a part number for the plate....if none available then I will have to make one.......would prefer one that is already made with perfectly aligned screw holes already made. Other than that, good quality and quick shipping...

Build a circular saw crosscut sled with these. They glide smooth, don’t rack, and somehow the sawdust doesn’t affect them (yet? But if so in the future it’s likely my fault and I’ll need to clean and grease). The picture is from the work in progress building, but my review is based on my experience after building a couple cabinets and using them for a bit.

The rods are solid and quite heavy. The blocks move very smoothly with no discernible play. I made a router sled with 2 pairs of these. My only concern is that there was a little bit of sideways twisting when the router was near the end of the rods. It did not really affect the router's perfotmace.

Smooth and well put together.

The flex on theseMake making no good to build a router sled with them I know it's not what they were meant for but they at least should not have had as much bow in it as it did for the kind of steel it is. Definitely will be purchasing the one that has the underlay in it to help keep it more stern and sturdy.

Made a router sled with one pair of these , another pair of the ones with a base, and three pieces of acrylic. Works great. Strong rigid rail rods. Surpringly good value.

This unit came As advertised. Cant wait to use it check it’s tolerance and smooth working .the standard measurement of the slide bearing set needs to better advertised due to the other units are not capable of being used on longer units from the same company.

Works perfectly! Saved a lot of money! I couldn't have built a better router sled. I would definitely recommend.

Used these to create my own flattening table for my wood working. Even with the saw dust the guides slide effortlessly.
