Customer Reviews for VEVOR Linear Rail Slide 2PCs 16mm x 1000mm Linear Bearing Slide Set with 4Pcs Block Bearings SC20UU+4Pcs Shaft Support Linear Shaft CNC Parts Kits for Electronic Equipment Guide Bar

In combination with a solid carrier rail, this provides the best low profile and strength for a leveling router sled.

Awesome product at a fantastic price. These would have cost ten times as much from Misumi. The quality is rock solid.

The product is very nice but shipping was very slow.

Great product, works well. They should really have the thread size listed either on the product page, or at least with an insert that comes with the product. The thread size on the blocks are M6-1.0, and the mounting holes on the ends are also drilled for M6. Yes, I docked a star for the trouble of having to figure out the thread size via trial and error, as well as thread depth. Which, with internal threads (especially in aluminum) can easily strip/damage the thread start. Also, the threading is about 1/2\" deep on the blocks. 25mm length M6-1.0 cap screws were about 3/16\" too long when mounting a 1/4\" plate. So, 20mm thread length on cap screws.

These rails came in today and are absolutely perfect. The quality exceeded my expectations!

10 years ago this would have been $500. It’s extremely nice and extremely precise.

I have received unbeatable service from VEVOR TOOLS with high quality products and at a price that I could afford.

See review I gave for the 2200mm rails which were in the same order. The guide blocks included with these rails are well designed and much easier to attach to my acrylic router plate because the mounting holes are drilled all the way through. I just laid the block on the acrylic and used the holes as a template for drilling. You should be using the same design blocks for the side rails!!!

The SBR cross rails were delivered on time, work perfectly and were easy to install and align on my flattening table.

I recently bought a stereo microscope head and needed a stand for it. The best stands are double arm boom stands, which use two linear rails. I have a 3D printer, so I figured, why not just build one? Looking at McMaster-Carr, linear rails and pillow blocks are EXPENSIVE. I looked elsewhere online, and they still weren't anywhere near what I wanted to pay. So then, of course, I checked Amazon and found these. I probably could have gotten away with the 16mm rails for my application, but I decided on the 20mm x 1m. First of all, they're super heavy. I guess that should be expected. They have a nice coating of oil on them, which seems to get on everything like anti-seize does - nothing a little brake cleaner can't take care of. The rails are straight and have a nice polish, and they measure 20mm +0.1/-0.2. The ends aren't chamfered, which would have been preferable, but that's an easy fix. The pillow blocks seem well made, with recirculating ball type bearings in them. Putting the two together, the blocks slide nicely on the rails, though they're a bit loud. The dust seals on the blocks seem to be well-fitted and there's no discernible play in the bearings. I need to cut these rails down, and I did so using an angle grinder with a cutoff wheel. I then polished and chamfered the ends with a 120 grit flap disc. Cutting took a couple of minutes per cut. You could probably do it with a hacksaw but it'll take you all afternoon. Out of curiosity, I tried drilling into a piece of the rail and I was able to drill without too much problem, so the rails aren't too terribly hard. Overall, these are a great choice if you need a set of linear rails, pillow blocks, and mounting blocks. I'll be posting my build to Hackaday and thingivese, and I'll be recommending these rails to anyone looking to build their own microscope stand.
