Customer Reviews for VEVOR Linear Guide Rail Set, SBR20 2200mm, 2 PCS 86.6 in/2200 mm SBR20 Guide Rails and 4 PCS SBR20UU Slide Blocks, Linear Rails and Bearings Kit for Automated Machines DIY Project CNC Router Machines

Bought these to upgrade an ancient cable drive ShopBot for my guitar-making hobby. For this application they look like they will work great, far better than the screen door rollers and unistrut used on the bot originally, and better than my previous upgrade to v-groove bearings and steel angles. For sure good enough for my occasional woodworking needs. Like a previous reviewer, I received four bearings not listed in the description, so now I have spares! I don’t think I’d put these rails on something that I rely on for a living unless I bought spares, and they seem a little noisy but hey, when the router is running I won’t hear it anyway.

Received in good shape exactly as described.

Nice finish, looks good, bearings roll well.

the product quality is as I expected. The linear bearing are much better than the standard ones in term of quality. The seller speeded up my purchase and I got it on time. I recommend this item.

I ordered this for a CNC machine, was shipped Fedex the same day. There is no play of any sort with these rails and fully supported from one end to the next. I don't think the bearing were in the description, but they sent 4 open block bearings. I just ordered another set this week and have been shipped the same day. If you need good supported rails, I would order from them again.

Built a horizontal boring machine with these rails. Works great.

I wasn't expecting what I received. These rails are professional quality that can more than likely accommodate a ton of load, honestly, 2,000 pounds. I don't know for sure, but man, these babies are perfectly chromed and glide so smooth. I have a Snap-On 9 drawer from the 1950s loaded with 200 lbs or more weight, and the rails and slides let you move the chest with a single finger.

Very good quality at a fair price.

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

good
