Customer Reviews for VEVOR Linear Rail SBR20-1000mm 2 Linear Slide Guide with 4 SBR20UU Bearing Block

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.

Well made and fit for purpose

Works great for what I used it for, made a slab plainer

Rails worked perfectly for my application, which was a bit non traditional. I used them to create a three point stress testing rig to measure the Young_ modulus gif various materials. The rollers were smooth with little play and should work for all but the most stringent applications.

I am absolutely amazed at the quality of these! I have had absolutely no issues in my use of these at all. These are just as good as the name brands but at a much better price! I would definitely recommend purchasing these!

These rails are excellent. I_e set up a flattening router jig and it works a treat, much better than the previous wooden one I previously had.Also a word about the seller. Outstanding.

Usato per creare una slitta per la fresatrice,Scorrono molto bene, si sente un pochino il saltello tra una guida e l_ltra, ma con un po di pazienza, si riescono a regolare bene.L_deale sarebbe avere un fine corsa da montare e smontare.

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!!!!

Guida robusta, priva di giochi, utilizzata su una CNC fa il suo dovere

havnt use them yet but semes like thay are good
