Customer Reviews for VEVOR Linear Guide Rail Set, SBR20 800mm, 2 PCS 31.5 in/800 mm SBR20 Guide Rails and 4 PCS SBR20UU Slide Blocks, Linear Rails and Bearings Kit for Automated Machines DIY Project CNC Router Machines

I have studied, researched and looked far and wide at multiple options and then I discovered this system.On a line of one to ten, I rate this a full ten. It was the perfect choice for my application where I required precision movement for sake of accuracy for making large timber cuts with my electric chain saw. It solved my problem with the utmost satisfaction. As for load bearing capacity with four carriage blocks the weight distribution is excellent for guiding the chainsaw and bar for making plunge cuts. With a secondary horizontal linear rail system it guides the horizontal cut making for a superb cut. Highly recommend the quality that was put into this system. I purchased the metric bolts from ACE HARDWARE and was amazed at the ease and precision the bolts inserted so well. The quality of the carriage blocks are what you would expect. The stainless steel rails allow the carriage to glide with ease.Highly recommend. Hope this helps.

The rails were nice and straight, no bowing, and the SS tracks are well polished. The linear bearings need some adjustment to get them to run relatively smooth. Even after adjustment, the bearings seem rough until you put a load on them after which they run nice and smooth.These work well for my purpose (linear guide rails), but I would hesitate to use them for high precision or low load applications (CNC, printing) simply due to the way the bearings behave without a load.

Excelente producto recomendado 100 %

I was not sure what to expect at this price point. I am accustomed to paying many more times the price for similar product from our favorite "McM... " store. Anyway I am extremely pleased by the quality at this price point.I rarely leave reviews but had to for this product!

Good for my expectations and work perfect

Excellent machining tolerances. The quality was better than I had expected.

Quick shipping. Perfect for my router sled.

Good item, however there is not template for the sliders that is not easy to align.

I'm sure these will be great when I am ready to use them. The idea I have for them is to be used as a flattening sled for large wood projects. I read reviews that stated that they used this for the same idea and it worked great. I will revisit this review once I have built my sled

the product was just what i needed to make a slab flattening jig
