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

These things are rock solid and extremely heavy duty. would definitely buy again, and in fact, I did.

good

made a table saw slide table

Rods have a nice smooth finish, heavy weight for lasting use. The slide blocks are also well made and slide easily along the rods. The tap holes are threaded for M6 bolts and about 3/8" deep.Great for quickly putting together a router sled if you buy two sets. Easy enough to mount permanently or use "as needed." You can find the video for doing that on youtube. .

These rails are great. Very solid and straight. Bearings move easily.

Everything you'd expect. Straight, clean rails that are working perfectly to support my router sled. No problems or complaints.

The blocks could be better cast with better cut threading but overall seem to be pretty straight and strong. Using as guide rails for 10mm thick 410x410 aluminum plate for custom 3d printer. So far with about 20 hours of use on them they have tracked fairly well.

Hubby is happy. They're doing the job nd he'll be purchasing more.

Used in the fabrication of surface planer!!!
