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

Great for the router sled project I'm working on.

I needed a rail system that is completely straight, and these fit the bill. The only critique I have is the bearings on the slides could be a little smoother.

This was a reorder of an earlier purchase of linear rails and bearing blocks. The first set of rails/blocks were used for making a router sled. This set of rails/blocks were also well made. The only difference was this set of bearing blocks were threaded for M-5 bolts, about 12 mm deep. The first set of bearing blocks were sized for M-6 bolts (assuming same depth).There is no problem with that, just be aware there may be a difference. All the bearing blocks use an Allen wrench bolt for locking the blocks to the rail.

Tight tolerance, smooth function. Great finish! Impressed by the price for the value-

Works great. Not disappointed in quality. Great deal for the price.

Quick shipping, quality item. Purchased two sets, & will be a return customer. Thanks for the outstanding service!

Product was as billed. Would order again from this vendor.

This is a awesome product! I was able to finish my laser machine . Some people say that the blocks are too loose, some are but they have adjustable screws to make them the right tension.

havnt use them yet but semes like thay are good

This was very helpful in my project. Used it to build a guide rail system for a cnc machine. Worked wonderfully!
