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.

Awesome product! I was able to finish my laser machine and worked perfectly.Some of the blocks are loose but all you need to do is use the screws on the side to adjust them.

They seem like good quality out of the box! Time will tell if the mechanisms hold up!

The bearing blocks moved smooth and were rigid.I pushed the bearing blocks onto the rails easily.Very good quality for very low price.

Exactly what I needed for a great price
