Customer Reviews for Linear Rail 2 X Sbr20-900mm Rails 4 X Blocks Automatic 2 Rails Slide Guide

These rails are not perfect but they are really good. Vevor had the cheapest price and free shipping so I was worried these might look like they were built by monkeys. Instead the smooth steel rods were clean, smooth strong and defect free. Lightly oiled and wrapped in plastic and foam to prevent rust or damage. The rollers are exactly what you would expect. An Aluminum cast piece that has been tapped for threads with a bearing added into the middle. They roll a little rough until you put a load on them then they quiet down and ride smooth. Don't want to oil them as it will mix with saw dust in my shop. The aluminum feet to the rods are probably the worst part of them. They are straight and flat but the mounting holes were drilled by hand. So they are not precisely located, spaced or even sized. Not a problem for me. So I will give it a 5 star as the price fits.

Made a router sled with these to flatten large planks, works great. Strong and straight.

Just wish they made longer ones.

Exactly what I wanted but I couldn't find where to order more of the blocks

Great quality love them they worked perfect

Excellent above standards

The rails were perfect for my router sled application. I will buy from Vevor again when the need arises.

I used this rail to make a sliding platform for an entryway into a house from a garage. I located the crawlspace access under the platform so you can slide the platform out of the way to enter the crawlspace. This product worked perfectly for what I needed to accomplish.

I have the rails installed and operational for a couple of weeks with not issues. everything was as advertised, The guide rails were straight and true. The truck bearings move smoothly when a load is applied. Fit and finish are good.

The blocks could be better cast with better cut threading but overall seem to be pretty straight and strong. Using as guide rails for 10mm thick 410x410 aluminum plate for custom 3d printer. So far with about 20 hours of use on them they have tracked fairly well.
