Customer Reviews for VEVOR Linear Guide Rail Set, SBR16 2000mm, 2 PCS 78.7 in/2000 mm SBR16 Guide Rails and 4 PCS SBR16UU Slide Blocks, Linear Rails and Bearings Kit for Automated Machines DIY Project CNC Router Machines

I used this product for a slab flattening jig with my router. Even with a very dusty environment, the bearing slides easily, maybe even too easily as I went off the end of the rails once, but that is really my bad. I wish that there were female threads at the end of the rails inline with the rail axis to facilitate adding a stop to prevent going off the end. When it went off the end, a single ball bearing did dislodged and was lost, but that still didn't prevent it from moving smoothly on the rails even after that.

Smooth sliders, using for router sled

excellent manufacturing, mounting blocks glide effortlessly.

They are very straight. Under load very smooth I will update when they are running

Great rails wish they would include a way to lock the bearing block or ship collars with it.

Although it was made of a lesser grade of stainless steel than much more expensive versions, it filled the need perfectly for lathe table work.

Exactly what I expected. Ball bearings are low quality, but was to be expected.

Perfect bearings slide smoothly, does as it should

These are perfect. They were just what I was looking for and they fit like they were custom made for me.

The only thing that I can complain about was the ups driver who threw the package on the floor sounded like something fell off the roof into my building .I just got to first floor as he was walking out with his cell phone at he ear !
