VEVOR 2x600mm Rails Linear Rail Shaft Rod Rail +4PCS SCS16UU Slide Bearing Block

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.

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.
