I bought these rails to fabricate a custom TV mount for a VERY large flatscreen we bought. I wanted to be able to slide the tv to the side to be able to access a hidden area behind the tv where the receiver, etc would be stored. The tv weighs in at 97 lbs, and I am able to slide it back and forth on these with a light touch of only 1 finger. They seem to be well constructed and are well worth the price.

worth getting more at the price I paid.

Very pleased with these rails, recieved them fast. These rails are good built with high quality parts. Rails roll nicely and seem to support a good amount of weight. I had some questions for the seller and they were prompt and very helpfull.

A great buy for the money. Rails are nice with just a few surface scratches. Bearings are not perfect and each one has a different feel to it. I cleaned an oiled them and a lot of metal shavings were in there. Definately clean these.Packaging was great and fast shipping.

Bearings are a bit rough. Rail is straight and true until the end screws securing it to the rail. The rail bends up a little on both ends. Side to side is good.

Super I wanted this items long ago for a projectSomething like a sliding table and they are perfectfor my table I’ll will recommend this items to any home hobbyist. they are perfect for projects with a retractable or sliding mechanism.

I would not use these on a CNC machine, but for making tight tolerance slides for other applications, they are just fine.The linear motion bearings can be a bit rough when they roll, catching at points and rolling fine at others, like the balls have flat spots, but can’t visually see anything wrong with them.

Good product. I need a 16-2000mm ball screw and parts for them.

This is going to be great for the machine I’m building. I’ve seen people ask about using these spanning over distances all on its own. . The answer is no, the item needs to be bolted to a flat framework to have any type of accuracy. Out of the package it’s not flat. But easily manipulated as you bolt it to you flat surface. Great guide system for the budget user. Excited to put it to use
