Customer Reviews for VEVOR Linear Guide Rail Set, SBR20 1500mm, 2 PCS 59 in/1500 mm SBR20 Guide Rails and 4 PCS SBR20UU Slide Blocks, Linear Rails and Bearings Kit for Automated Machines DIY Project CNC Router Machines

I noticed the blocks are not quite as smooth as I had hoped, but they do the job quite nicely. I used only one of the rails so far. I had to cut it to fit my cheap 3d printer. I replaced the flimsy 8mm tray rails with something a bit more substantial and much more robust. The carriage is much more sturdy now and auto-leveling the machine is much easier since the bed doesnt wiggle any more. It may have been a bit overkill, but thats my style.

Very satisfied with the quality and price....would definitely buy with them again.....especially like the fact that after receiving items, the seller emailed me asking if items were delivered and was I happy with them.....GREAT job!!!!

Not the best linear rails, but with some adjustment, they turned out to be very good. A little noisy, but perfect for my applications.

They are a nice set of rails but they do not come with pre-drilled holes for mounting.

These linear rails came well packed and shipping was fast. They appear well made and heavy duty. These are the second set I have gotten and would buy them again. The surface hardening is really tough. If they must be cut forget the hacksaw they need to be cut with an abrasive wheel. A dremmel will do the job. It took 2 discs to get through it.

i bought them to use as part of a break down router sled, they work great!

Rails are very sturdy and well built.

Sturdy assembly, no bend or sway... Performed as advertised.

highly exceeded my expectations for price point. Excellent quality!
