Review: Great linear rails for a great price - 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 desertcart 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.
Review: Perfect for my needs! - I'm new to retirement and woodworking, so this may be the wrong way to do this but I am THRILLED with the results! I was looking to build a very wide, shallow, relatively deep drawer under my workbench to store my long straight edges and things I use every day. I mounted the glide rails to the bottom of the drawer and the slide blocks to the frame I already had underneath. I dropped a few bolts into the back end of the glide rails to prevent the drawer from coming out too far. End result is awesome! It's the little things in life! Rails are strong, solid, and straight. Slide blocks also seem solid (the ones I got accepted M5 machine bolts) and I am optimistic the ball bearings will last. Thank you!

### ⭐⭐⭐⭐⭐ Where's the 6th star!
*by M***L on December 6, 2025*

I cannot say enough good things about the product quality and the value. For $28, I cannot understand how the company isn't losing money. The product weighs a ton and shipped UPS. The machining on the rails is sick. I was thinking I was going to cut them down but I have no idea how I'd get through these things now. They are incredibly dense and strong. Great company and product. Thank you for making this affordable!
