Customer Reviews for SBR16-800mm 2x Linear Rail Set 4x Bearing Block Mechanical CNC Set Machinery

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.

Haven't yet

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

Package was delivered on time with no damage. I am pleased with the product.RP

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.

I am very pleased with the quality of the linear rails and smooth operation. The customer service was outstanding. I has some issues with installing the ball nut and the bearings fell out. The company didn't have the nuts locally and had them sent from china at no additional cost. They provided updates to let me know about delay because of the extended holiday.
