Works great for what I needed, though heavier then I thought it would be. Very strong and slides very well

I ordered by mistake. They refunded w/o quibble. Super HQ build and smooth running but NOT completely silent. 100% guaranteed for BIG DOORS!!

Product purchased as part of a Router Sled to resurface River Table. This was purchased in conjunction with Aluminum bars also purchased from Amazon. I am very pleased with the end result. The Guide Rail Set performed very well. The rails are well constructed and straight and the bearing work very well. I was able to plain the surface to a precision smoothness that required very little sanding. Recommend this product.

Used these on a flattening sled in my woodshop. They were straight and true to size. Would buy again.

Bought the SRB20-1000 and SRB20-1800. Was having problems getting bolts into the SRB20UU bearing holes. Document said M6-1.0. Had to run a bottom tap into each hole. Had a lot of material clogging up the holes as you can see on pics. Got all 32 holes retapped and unit went together well. Slides work well with little to no drag. Not saying don't purchase, just saying have a M6 tap on hand and be prepared to spend a half hour retapping each hole.

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.
